Description

DEVICE, COMPONENTS, AND KITS FOR APPLYINGHAIR COMPOSITIONS AND THE MANUFACTURE AND USE THEREOFFIELD

[0001] The present disclosure relates to devices, methods, and kits for applying compositions to hair, including hair colouring, hair highlighting, and hair lowlighting compositions.BACKGROUND

[0002] Hair enhancements, particularly hair colouring and highlighting / lowlighting, are extremely time consuming and complicated, and require the services of trained colourists. A considerable amount of lost time and inefficiency at salons arises from the need to regularly prepare foils for the later use in salon client’s hair. In addition, the foil wrapping process is very involved with stylist / colourist having to hold their fingers and foils in precise orientations to section and secure the hair for colouring to achieve the desired colouring result. Delays caused during colouring and highlighting / lowlighting cause downstream delays in haircuts, straightening, and styling. All of this, in turn, reduces the throughput / volume of customers that salons can manage, and substantially increases costs for both salons and customers alike.

[0003] Additionally, hair foils and their application lead to inconsistent results. The top edges of foils are straight and unable to flex. This linearity and inflexibility produce irregular and inferior treatment. Because the top edge of the foil is rigid and straight, it cannot follow the contour of the scalp. Only the centre point of the top edge actually contacts the scalp when the foil is put into place. To either side of this centre point, the top edge extends away from the scalp. This means that a composition cannot be applied in even amounts to the section of hair in the foil. The hairs positioned precisely at the centre point of the foil can be treated all the way up to the scalp, given that the centre point contacts the scalp. The hairs positioned at any other position on the foil (to the left or right of the centre point) cannot be treated all the way up to the scalp. In addition, the progressive application of foils and application of the colour composition means that earlier applied foils have an extended exposure to the composition as compared to later applied foils. In the short term, this produces variations incolouring / highlighting / lowlighting (e.g., blotching) over the head of hair. In the long term, this causes damage in certain regions of the hair, i.e., regions that are regularly over exposed.

[0004] This increased exposure increases the potential for skin sensitivities such as dermatitis, and for serious allergic conditions such as anaphylaxis. It is noted that most hair colour and highlighting / lowlighting compositions contain known sensitisers such as 1,4-phenylenediamine (PPD) and 1,4 -toluenediamine (PTD). There is also increased risk of toxicity and illness from chemical exposure. Many hair colourants and highlighting / lowlighting treatments use chemicals, such as peroxide, alkalizers, ammonia, metal oxides including titanium dioxide and iron oxide, and a variety of other agents. Many of these chemical agents are toxic and some are classified as carcinogens. Because foil based application methods are inherently imprecise (lack of contouring, lack of uniformity, etc, as noted), this means that the noted chemical agents can contact the scalp, forehead, neck, ears, and other parts of the head each time that treatment is carried out.

[0005] From the customer’s standpoint, foils are inconvenient, awkward, and dated. The appearance of foils in one’s hair is highly unattractive. Foils often result in “blotches” of colour due to their imprecision (lack of contouring, lack of uniformity, etc, as noted). For the same reasons, foils can result in skin irritation. These effects are concerning to the customer. Moreover, there is a considerable and negative impact on the environment, given the single use nature of the foils, how the foils are made, and the source of materials used for foils. Foils are produced in an energy intensive process from non-sustainable materials. The single use nature of foils means that there is substantial waste. At the end of each hair treatment, the large pile of foils is discarded. This is problematic given the increasing focus of salons and colour manufacturers to join sustainability programmes, and the increasing awareness of customers as to environmental and sustainability issues.

[0006] Therefore, there is an ongoing need in the field for alternative means for applying colouring, highlighting, lowlighting, and other compositions to the hair.Particularly noted are means that provide improvements in one or more of: efficiency, accuracy, customer satisfaction, customer well being, and environmental considerations.SUMMARY

[0245] The following description sets forth numerous exemplary configurations, parameters, and the like. It should be recognised, however, that such description is not intended as a limitation on the scope of what is disclosed, but is instead provided as a description of exemplary embodiments.Definitions

[0246] In each instance herein, in descriptions, embodiments, and examples of the present disclosure, the terms “comprising”, “including”, etc., are to be read expansively,without limitation. Thus, unless the context clearly requires otherwise, throughout the description and the claims, the words “comprise”, “comprising”, and the like are to be construed in an inclusive sense as to opposed to an exclusive sense, that is to say in the sense of “including but not limited to”.

[0247] As used herein, “approximately” or “about” means up to 10% greater or up to 10% lesser than a particular value. This includes up to 2% greater or up to 2% less than the value, or up to 5% greater or up to 5% less than the value, or up to 6% greater or up to 6% less than the value, or up to 7% greater or up to 7% less than the value, or up to 8% greater or up to 8% less than the value, or up to 9% greater or up to 9% less than the value.

[0248] The directional terms “top”, “bottom”, “upper”, and “lower”, as used herein are defined relative to application device, given the viewpoint of a user engaging with the device, for example, in attaching to or removing from the hair on the back of the head.

[0249] The dimension of “length” (or “height”) for the device is determined by measuring the device from top to bottom, with the user looking at a vertically oriented device. The dimension of “width” for the device is determined by measuring the device from left to right, with the user looking at a vertically oriented device.

[0250] The dimension of “depth” for the device is determined by measuring the device from front to back, with the user looking at a vertically oriented device. The width and depth may be measured at the top or bottom of the device.

[0251] “Essentially vertical” encompasses an orientation that is up to 10° out from true vertical. “Essentially identical” encompasses a dimension (e.g., length, width, height or depth, for example, length ‘A’) that is up to 10% greater or lesser than the dimension being compared (e.g., length, width, height or depth, for example, length ‘B’).

[0252] Various shapes and configurations, as referred to herein, e.g., “quadrilateral”, “rectangular”, etc, can be, but will not necessarily be, precise by mathematical, geometric, or engineering standards. Approximations of such shapes and configurations (e.g., essentially quadrilateral, essentially rectangular) are thereby included in this disclosure.

[0253] As used herein, a “composition” refers to a substance applied to hair. This can be, for example, a liquid, gel, cream, or paste, or other formulation for the hair. Colouring and highlighting / lowlighting compositions are specifically noted, including bleaching, dyeing, tinting, toning, ombre, glossing, and glazing compositions, as well as permanent, semi-permanent, demi -permanent, and temporary colouring compositions. Compositions having natural components, e.g., henna, cassia, or indigo compositions, are also included.

[0254] As used herein, a “clip” refers to an engagement component which can be, for example, arcuate or essentially arcuate in configuration. Clip components can be provided as pairs (e.g., top clip component assembled with bottom clip component), or can be provided individually (e.g., top clip component and bottom clip component provided without assembly).

[0255] As used herein, a “flap” refers to a supporting or covering component which can be, for example, quadrilateral or essentially quadrilateral in configuration. Flap components can be provided as pairs, or can be provided individually.

[0256] “Connecting”, as used herein, refers to provision of an association or linking between two or more components. Connecting can be direct or indirect, and can be reversible.

[0257] “ Other means”, as used herein, includes additional means, as well as any combination of the means being recited.Device and components for applying hair compositions

[0258] The present disclosure encompasses a device for applying compositions to the hair, including hair colouring and highlighting / lowlighting compositions. The device is designed to provide ease, consistency, and efficiency for application, substantially improved safety and accuracy for applying for compositions, and sustainable and reusable componentry. The device is designed to prevent or significantly reduce incidences of undesirable colour variations, hair damage, and scalp irritation. The device is designed to allow for substantially faster application, and to have an appealing and modem appearance for customers. The device is designed to produce superior results.As examples, the device allows placement of a hair composition onto each section of hair at the closest proximity to the scalp (ideally, without over shooting onto the scalp and adjacent hair), such that each section of hair is treated uniformly and that the composition is applied along the same distance from the scalp. In addition, testing has revealed that the device: lifts colour faster; delivers a superior quality result (smoother, more even, cleaner colour); and assists in delivering defusing techniques (e.g., “root melt”). Further to these aims, it is the aim of this disclosure to at least to provide the public with a useful alternative.Clip component

[0259] The device disclosed herein may comprise a clip component. The clip component is designed so as to secure the device in position. The device may be secured, for example, proximate to the scalp, adjacent to the scalp, or onto a section of hair (e.g., not adjacent to the scalp). The clip component thereby provides a point of engagement with the hair. The clip component also helps to protect the scalp from contact with the composition. In particular aspects, the clip component can be positioned adjacent to the scalp, and provide an effective barrier for the scalp. In this way, the scalp is essentially sealed off from the composition.

[0260] In various aspects, the clip component may include one or more projections for engaging with a section of hair. For example, the clip component may include on its length one or more teeth or other projections to allow fastening to a section of hair. The one or more projections may be of a similar size or may be different sizes. The size of the projections may be graded, e.g., gradually increasing in size towards the centre of the clip component. A plurality of projections may be utilised, for example, a plurality of teeth, bulges, humps, jags, juts, ridges, or other means. The angle of the projections (e.g., teeth, etc) can be modified as described herein.

[0261] In particular aspects, the clip component may be designed as arcuate or essentially arcuate in its configuration. For example, the clip component may be contoured in such a way as to generally follow the curvature of the scalp. In certain exemplifications, the clip component may be a concave or essentially concave in shape. The clip or a portion of the clip may be deformable so as to enhance a concave oressentially concave shape at the leading edge. The clip component may have different widths, lengths, spans and curvatures. In this way, the clip component can be adapted to different areas of the scalp and / or different scalp sizes and shapes. Thus, a kit as disclosed herein may include clip components of varying dimensions and curvatures.

[0262] As one embodiment, the portion of the clip component that contacts the hair is tapered and / or elongated. This allows the closest possible connection to the scalp, while at the same time forming a safety boundary to prevent the composition from contacting the scalp. The tapered design also assists in making a positive connection with the section on hair, thereby securing the clip component in place.

[0263] The clip component may be designed to prevent the colourist from overshooting the composition onto the scalp. Similarly, the clip can be designed to catch any product that swells or migrates during treatment. In specific aspects, the clip component may include one or more impedance means so as to prevent or reduce contact between the composition and the scalp. This impedance means can be provided by one or more projections or other shapes for the clip component (e.g., one or more lips, ribs, rims, ridges, shoulders, teeth, guard rails, or other means) and / or one or more ingresses for the clip component (e.g., one or more channels, dimples, slots, ruts, or other means). Various exemplifications for projections are provided herein. Combinations of projections, shapes, and / or ingresses may also be used.

[0264] The clip component may be provided individually or as a paired set. For example, single components (e.g., separate top clip components and bottom clip components) may be connected together by the user to form a paired componentry for clamping onto a section of hair. As an alternative, pre-connected and paired clip components can be provided (e.g., top clip component assembled with bottom clip component) to allow clamping onto a section of hair. In certain circumstances, the paired clip components are connected via one or more hinging means. Such means allow for the paired componentry to be readily open and clamped closed over a section of hair.

[0265] For a paired set of clip components, the one or more projections (e.g., one or more teeth, bulges, humps, jags, juts, ridges, or other means) of the individual components may provide securement when the paired set is clamped closed. In this way,the paired components can hold a section of hair more tightly. For example, a plurality of teeth of the top clip component may fit into a corresponding plurality of cavities of the bottom clip component. Alternatively, a plurality of teeth of the bottom clip component may fit into a corresponding plurality of cavities of the top clip component. As a further alternative, a plurality of teeth of the top clip component may interlock with a corresponding plurality of teeth of the bottom clip component.

[0266] Therefore, in certain aspects, it may be suitable to include one or more securing means to keep the paired clip components in a closed position, e.g., clamped onto a section of hair. Exemplifications include projections (e.g., teeth, bulges, humps, jags, juts, ridges, or other means) as noted above, as well as magnetic closures, hooks, loops, hook and loop materials (e.g., Velcro®), clips, pins, snaps, and other means. As further examples, the top clip component and the bottom clip component may clamp together via a tongue and groove configuration. Alternatively, the top clip component and the bottom clip component may clamp together through complimentary opposing tongues that abut together.

[0267] It is also possible for the paired set of clip components to include one or more releasing means. In this way, the paired componentry can be transitioned from a closed position (e.g., clamped onto a section of hair) to an open position (e.g., released from the section of hair). Exemplifications include pins, buttons, levers, and other means. As an example, a releasing means may be positioned proximate to a hinging means for the paired clip componentry. In certain aspects, the releasing means (e.g., lever) may be offset from the assembled top clip component and bottom clip component so that it does not get in the way of another paired set being attached onto to a section of hair that is in proximity to the original paired set.

[0268] As an alternative to hinging and releasing means (e.g., as in Figure 15A), it is possible to use guiding means and releasing means (e.g., as in Figure 15B). In this way, it is possible to use an “alligator clamp” embodiment for the paired clip componentry, or a “parallel clamp” embodiment for the paired clip componentry. Other embodiments are also encompassed. Notably, the opening of the paired clip componentsallows the insertion of a section of hair at the beginning of treatment, and also allows the releasing of the section of hair at the end of treatment.

[0269] In one specific aspect, the clip component can include one or more engaging means for interaction with a comb, brush, pick, applicator or other tool. The engaging means may include recesses, projections, or various combinations of these. For example, the clip component may include a bore or slot (e.g., hexagonally shaped bore) that can be engaged by an appropriately configured tool (e.g., having an Allen key-shaped handle). Other arrangements are also possible, for example, two or more projections (e.g., loops, hooks, clips, pins, snaps, or other means) can allow engagement between the comb, brush, etc. and the clip component. These arrangements can be used to engage with and adjust the clip component, and reposition the clip component when needed. It will be understood that bores, slots, hooks, etc, are some of the available options, and that the engagement means and the corresponding tool can be any appropriate shape to allow interaction.

[0270] The materials used for the clip component may be natural, non-natural, or combinations thereof. Nonlimiting examples include metals, plastics, resins, and any combination of these. Specifically noted are components constructed from one or more durable plastics, such as polyethylene (e.g., HDPE or LDPE), polypropylene, or polycarbonate. Also noted are components constructed from plastic coated metals, e.g., nylon covered aluminium, or nylon covered aluminium alloys. Other metal and non- metal materials may also be suitable.

[0271] In specific examples, clip components may be approximately 20 mm to approximately 200 mm, approximately 30 mm to approximately 150 mm, or approximately 40 mm to approximately 120 mm in length. Exemplary lengths for the clip components include: at least 20 mm, at least 30 mm, at least 40 mm, at least 50 mm, at least 60 mm, at least 70 mm, at least 80 mm, at least 90 mm, at least 100 mm, at least 110 mm, at least 120 mm, at least 130 mm, at least 140 mm, at least 150 mm, and at least 160 mm.

[0272] In further examples, clip components may be approximately 4 mm to approximately 160 mm, approximately 5 mm to approximately 150 mm, approximately6 mm to approximately 120 mm, or approximately 10 mm to approximately 100 mm in width. Exemplary widths for the clip components include: at least 4 mm, at least 5 mm, at least 6 mm, at least 7 mm, at least 8 mm, at least 9 mm, at least 10 mm, at least 15 mm, at least 20 mm, at least 50 mm, at least 100 mm, at least 120 mm, at least 150 mm, at least 200 mm, and at least 250 mm.

[0273] In further examples, clip components may be approximately 3 mm to approximately 170 mm, approximately 4 mm to approximately 160 mm, approximately 5 mm to approximately 150 mm, approximately 6 mm to approximately 120 mm, or approximately 10 mm to approximately 100 mm in height. Exemplary heights for the clip components include: at least 3 mm, at least 4 mm, at least 5 mm, at least 6 mm, at least 7 mm, at least 8 mm, at least 9 mm, at least 10 mm, at least 15 mm, at least 20 mm, at least 50 mm, at least 100 mm, at least 120 mm, at least 150 mm, at least 160 mm, and at least 170 mm. Other sizes may also be suitable. It will be understood that device is not limited to any particular size or type of clip component to be used.

[0274] In certain embodiments, the clip component may be provided in one or more colours, e.g., with colour coding, to assist in the colouring or highlighting / lowlighting process. For example, different sized clip components may be provided in different colours or shades. This could assist the colourist in identifying the correct clip component for a particular colouring / highlighting / lowlighting project. Optionally, the clip component (or a portion of the clip component) may be provided as a transparent or essentially transparent material. This could assist the colourist in seeing the scalp and identifying any ingress of the composition onto the scalp. In particular aspects, the clip component may include a bench portion, e.g., a flat portion where the flap component can be mounted. The bench portion may be included on the top clip component or the bottom clip component, or on both top and bottom clip components. The flap component is described in further detail below.Flap component

[0275] The device disclosed herein comprises a flap component. The flap component is designed so as to support / cover a section of hair and / or to support / cover a portion of the composition. The flap component thereby provides a means for facilitatingcontact between the hair and the composition. This facilitation can assist with heating the hair and / or the composition, and thereby accelerating the treatment process. The flap component also helps to protect the scalp and surrounding hair from contact with the composition.

[0276] In certain aspects, the flap component may be designed to be folded over a section of hair, or to be rolled around a section of hair to provide treatment. For example, the flap component may be placed under the section of hair, the hair composition may be introduced to the section of hair, and then the flap component can be folded on itself or rolled up on itself to ensure contact between the section of hair and the hair composition. Alternatively, at least two flap components may be utilised in combination to cover a section of hair, e.g., “sandwiching”. For example, a first flap component may be placed under the section of hair, the hair composition may be introduced to the section of hair, and then a second flap component can be placed over the section of hair to ensure contact between the section of hair and the hair composition.

[0277] As described herein, the flap component can be designed to include one or more one thermoplastic elastomer such as SEBS. These one or more materials can advantageously provide the qualities of sufficient tack or stickiness such that interassociation or intra-association of the material(s) is possible. For example, a flap component including such material(s) can be rolled or folded on itself and retained in such configurations without the addition of other attachment means. Where two flap components include such material(s), one flap component can be held on top of another flap component (e.g., sandwiching) without the addition of other attachment means. This significantly streamlines the utilisation of the device as described herein.

[0278] It is possible to use the flap component(s) alone and without including other features, e.g., without one or more clip components, or tensioning means, or locking means, etc. It is also possible for the flap component to be provided such that it is adapted to be connected to a clip component. Alternatively, the flap component may include one or more means for connecting to the clip component, and the user can affect the connection. It is also possible for the clip component to include one or more means for connection to the flap component. It is further possible for both flap component and clipcomponent to include connecting means. Exemplary connecting means include rings (e.g., spiral rings, axial rings), loops, hooks, clips, pins, snaps, and other means.

[0279] In certain aspects, one or more connections between the flap component and the device may be reversible, such that the flap component can be removed. For example, the flap component may be temporarily detached from the device (e.g., for washing) and then reattached. As a further example, the flap component may be detached from the device and substituted with another flap component. This allows different flap components to be utilised with different hair treatments. This also allows any damaged flap components to be removed and replaced, as needed. In the same way, one or more connections between the positioning means (e.g., plurality of teeth) may be reversible, such that the positioning means can be removed from the device. This can be, for example, for washing the positioning means, or replacing the positioning means. As an example, it may be desirable to substitute different positioning means to obtain different angles or different projections for the particular treatment being utilised. Any damaged positioning means may be removed and replaced, as needed.

[0280] As one exemplification, the top edge of a first flap component can be connected to the bottom edge of a first clip component. In the same way, the top edge of a second flap component can be connected to the bottom edge of a second clip component. With this arrangement, the pair of clip components can be clamped on a section of hair proximate to or adjacent to the scalp, while the connected flap components extend down from the clip components and cover the section of hair. This arrangement allows the efficient application of the composition onto the hair positioned on the lower flap component. Further, the hair composition stays in place on the section of hair that is positioned between the pair of flap components.

[0281] In another exemplification, one flap component can be attached: (1) on its back side to the front side of a first clip component; and (2) on its bottom edge to the top edge of a second clip component. With this arrangement, the first clip component can be engaged with a section of hair, and the second clip component can be clamped to first clip component, thereby folding the flap component back on itself. This arrangement allows the efficient application of the composition onto the hair positionedon the flap component. Further, the hair composition stays in place on the section of hair that is positioned under the folded flap component.

[0282] As a further exemplification, one flap component can be attached: (1) on its top edge to the bottom edge of a first clip component; and (2) on its bottom edge to the top edge of a second clip component. With this arrangement, the first clip component can be engaged with a section of hair, and the second clip component can be clamped to first clip component, thereby folding the flap component back on itself. These and other variations are feasible. For example, it is possible to attach only a bottom flap component to a bottom clip component, i.e., to omit the top flap component. It is also possible to attach only a top flap component to a top clip component, i.e., to omit the bottom flap component. It is further possible to attach only a bottom flap component or only a top flap component, and to fold the selected flap component back on itself. It is therefore possible for the single or paired flap components effectively act as a “rolled wrap” or a “sandwich” or a “folded pocket”, keeping the hair section in place, keeping the composition in contact with the hair section, and keeping the composition separate from the untreated hair and the scalp. Moreover, where the flap component is positioned close to the scalp, the composition will not bleed and produce coloured / lightened blotches.

[0283] In particular aspects, the flap component may include means for positioning the flap component onto the hair, such that a separate clip component or paired clip componentry may not be necessary. For example, the flap component may be positioned proximate to the scalp, or adjacent to the scalp, or onto a section of hair (e.g., not adjacent to the scalp). As exemplifications, one or more projections (e.g., teeth, bulges, humps, jags, juts, ridges, or other means), and / or one or more sticky material or substance may be included at or proximate to the leading edge of a flap component to assist with positioning. The one or more projections may be of a similar size or may be different sizes. The size of the projections may be graded, e.g., gradually increasing in size towards the centre of the flap component. As an exemplification, a plurality of projections (e.g., teeth, bulges, humps, jags, juts, ridges, or other means) along the leading edge of the flap component may be used to position the leading edge of the flap component proximate to the scalp, or adjacent to the scalp, or onto a section of hair which is not proximate to / adjacent to the scalp.

[0284] Where the positioning means includes a plurality of teeth (e.g., a comb arrangement), this design can be particularly advantageous. For example, the plurality of teeth can assist in separating strands of hair and in preventing contact between the scalp and the hair composition. This positioning and separation from the scalp can in turn can be employed in balayage colour techniques, diffusion colour techniques (e.g., “root melt”), and other methodologies. In certain aspects, the teeth can be presented on a forward facing angle relative to the flap component, e.g., approximately 130 to approximately 150 degrees, such that when the flap component is positioned, the teeth are perpendicular or essentially perpendicular to the scalp. Alternatively, the teeth can be presented at a lesser angle relative to the flap component, e.g., approximately 80 to approximately 100 degrees. By using longer and stiffer teeth, these can be combed through the hair and assist with the treatment application.

[0285] In specific aspects, the flap component may be designed as arcuate or essentially arcuate in its configuration, particularly where the positioning means (such as a plurality of projections) is provided. For example, the flap component may be contoured at its leading edge in such a way as to generally follow the curvature of the scalp. The leading edge may be arcuate or essentially arcuate in the horizontal and / or the vertical plane of the device. This can assist the device in hugging / cupping the contours of the head, and can also assist in stacking multiple devices together during the treatment process, and in stacking multiple the devices together in storage. In certain exemplifications, the flap component may be a concave or essentially concave in shape at its leading edge. The flap may be flexible so that when the leading edge deforms, the flap will follow, i.e., stretch and retract. In particular, the flap may be deformable so as to enhance a concave or essentially concave shape at the leading edge. The leading edge may be deformable in the horizontal and / or the vertical plane of the device. Again, this can assist with hugging / cupping the contours of the head and stacking multiple devices together. The flap component may have different widths, lengths, spans and curvatures. In this way, the flap component can be adapted to different areas of the scalp and / or different scalp sizes and shapes. Thus, a kit as disclosed herein may include flap components of varying dimensions and curvatures.

[0286] In other aspects, the flap component may be designed to prevent the colourist from overshooting the composition onto the scalp. For example, the flap component can be designed to catch product that goes beyond the flap surface. In specific aspects, the flap component may include one or more impedance means so as to prevent or reduce contact between the composition and the scalp. This impedance means can be provided by one or more projections or other shapes for the flap component (e.g., one or more lips, ribs, rims, ridges, shoulders, teeth, guard rails, or other means) and / or one or more ingresses for the flap component (e.g., one or more channels, dimples, slots, ruts, or other means). Various exemplifications for projections are provided herein. Combinations of projections, shapes, and / or ingresses may also be used.

[0287] The flap component (e.g., top flap component, bottom flap component, both top and bottom flap components, or a single flap component) may include one or more reservoirs. For example, one or more reservoirs may be used for holding the hair composition until contact between the hair composition and the section of hair is desired. The reservoirs may include one or more chambers. For example, separate chambers may be used for holding compositions that require mixing before use, or for holding compositions that are used sequentially. In addition, one or more reservoirs may be used to provide accommodation for the section of hair on the flap component. For example, one or more concave or essentially concave formations on the flap component (e.g., bubble formations, teardrop formations, or other means) may assist in accommodating the hair on the flap component. Again, these reservoirs may include one or more chambers. For example, separate chambers may be used to apply / maintain different compositions on different parts of the hair. Alternatively, separate chambers may be used to apply a composition to different parts of the hair at different times (e.g., sequential application). In certain aspects, a reservoir can include one or more transparent sections or essentially transparent sections (e.g., window(s)) to assist with inspection and monitoring of the treatment. For manufacture, the one or more reservoirs on the flap component may be moulded directly into the flap component, or may be produced separately and then attached to the flap component.

[0288] In such aspects where a flap component is utilised without a separate clip component or paired clip componentry, it may be helpful to include additionalfunctionality as part of the flap component. For example, the leading edge of the flap component may be provided so as to be deformable, particularly in the horizontal plane and / or vertical plane. This allows shaping and moulding of the leading edge to the customer’s scalp. To provide additional functionality, the flap component (side facing the scalp) may include a support body and one or more support arms. In particular aspects, the support body and one or more support arms may be presented in essentially a Y shape or wishbone shape, whereby the left and right arms reach towards the left and right of the leading edge of the flap component.

[0289] The support body and arms (e.g., wishbone shape, etc) may be designed to be arcuate or essentially arcuate in the vertical and / or the horizontal plane of the device. This can assist the device in hugging / cupping the contours of the head, and can also assist in stacking multiple devices together during the treatment process, and in stacking multiple the devices together in storage. Notably, the support body and arms, as well as the bracing elements (see below), assist in providing a solid platform against which an application brush can be pushed / pressed. This acts in a similar way as a balayage board. The support body may also include a locking mechanism, as described further below.

[0290] In certain aspects, the flap component may include one or more bracing elements. For example, the one or more bracing elements may include a plurality of elongated members (e.g., juts, palings, fingers, or other means) that span between the left and right of the leading edge of the flap component. The bracing elements (e.g., fingers, etc) assist in supporting the flap component where it is proximal to the leading edge. As an exemplification, the bracing elements may be positioned along the leading edge, and may span between the left and right support arms. In certain aspects, the bracing elements may be attached to the projections (e.g., teeth, bulges, humps, jags, juts, ridges, or other means), which assist in positioning the flap component. The bracing elements may also provide a platform which assists in application of the hair composition. In addition, the bracing elements may provide assistance in keeping the correct configuration for the leading edge of the flap component. In this way, the flap component may be enhanced by additional supporting / shaping features.

[0291] In particular aspects, the flap component may be designed as quadrilateral or essentially quadrilateral in its configuration. For example, the flap component may be shaped approximately as a rectangle or a square. One or more corners of the quadrilateral configuration may be rounded. Alternatively, the flap component may have even more of a curved shape, e.g., as oval, half-oval, elliptical, half-elliptical, stadium, half-stadium, pyriform, parabolic, or hyperparabolic configurations, or variations thereof. Other configurations and shapes may also be suitable. The top edge, or at least a portion thereof, of a flap component may optionally include edging to enhance engagement with a clip component. For example, the top flap component, the bottom flap component, or both top and bottom flap components may include edging to enhance engagement with the clip componentry.

[0292] As indicated above, the clip component may be arcuate or essentially arcuate in shape, and may have different spans and different curvatures. In the same way, the flap component may be sized and shaped to allow the appropriate connection with the clip component. In this way, a flap component can be matched with its corresponding clip component. Thus, a kit as disclosed herein may include flap components of varying sizes and shapes. In addition, in lieu of a flap component being utilised, it is possible for the clip component (e.g., the top clip component and / or bottom clip component) to have a shape or configuration to help prevent the hair treatment from contacting the scalp or other hair of the subject. That is, the top clip component and / or the bottom clip component can be adapted to have a built-in element that is comparable to a flap as described herein.

[0293] In specific aspects, the flap component may include or may be associated with a barrier means so as to prevent or delay contact between the composition and the section of hair until such contact is desired. This barrier means can be provided by one or more sheets (e.g., pull tab or other means) or one or more projections (e.g., pouch or other means) associated with or included with the flap component. For example, the composition can be positioned below the top most flap component and above the barrier means. The barrier means, in turn, sits above the section of hair. When the barrier is removed (e.g. tab pulled out) or otherwise traversed, the composition can come in contactwith the hair and processing can begin. Combinations of various sheets and projections may also be used.

[0294] As further aspects, the flap component may include one or more means to assist in securing and tensioning the section of hair. This may be helpful for when wanting to treat the full length of hair for a customer that has long hair. Exemplifications include one or more tensioning means, including one or more protuberances, such as one or more knobs, buttons, prongs, pegs, nibs, hooks, fingers, flanges, clasps, clips, hub and spokes, or other means. For example, the section of hair may be wrapped around or otherwise trapped or secured by one protuberance or more than one protuberance. The section of hair may be held in place between a plurality of protuberances, e.g., in a channel formed by the protuberances.

[0295] In specific aspects, a tensioning means may comprise a bar. For example, in the locked position, the bar may be pressed inward / downward onto the section of hair (towards the scalp), keeping the section of hair in place. In the unlocked position, the bar may be shifted outward / upward and away from the section of hair (away from the scalp), thereby releasing the section of hair. In accordance with this exemplification, the user can achieve locking by pressing inward / downward on the bar (e.g., particularly at the head of the bar) against the outward facing side of the device. This pushes the head of the bar inward / downward through the support body of the device, to protrude from the underside of the device (scalp facing side), where the head clicks into place. Conversely, the user can achieve unlocking by pressing upward the head that protrudes on the underside of the device (scalp facing side). This releases the head allowing the head to push upward / outward through the support body of the device, thereby shifting the bar upward / outward from the outward facing side of the device. Therefore, when the tensioning means is locked, the head of the bar can protrude from the underside of the support body. When the tensioning means is unlocked, the head of the bar can be flush with the underside of the support body.

[0296] In this particular aspect, the bar (e.g., the head of the bar), may be designed to penetrate the support body via a washer (e.g., a retaining washer). The washer may be engaged with the support body so as to keep the flap component in placeon the support body of the device. The washer may be countersunk into the upper side of the support body. By being countersunk, the washer can allow the hair composition to pool under the bar and can ensure contact between the hair composition and the hair that is tensioned under the bar. This is described in more detail below.

[0297] In other aspects, the bar can be swivelled in a clockwise or counterclockwise direction, and this in turn can allow the bar to be presented in an open or close position. For example, to open the tensioning means, the bar can be rotated in a clockwise direction and swivelled into an open position (e.g., vertical or essentially vertical relative to the flap component). To close the tensioning means, the bar can be rotated in a counterclockwise direction and swivelled into a closed position (e.g., horizontal or essentially horizontal relative to the flap component). As an exemplification, the section of hair can be placed on the flap component while the bar is in the open position. The bar can then be swivelled to the closed position. This holds the section of hair in place on the flap component.

[0298] In specific examples, the bar may be approximately 40 mm to approximately 160 mm, approximately 50 mm to approximately 150 mm, or approximately 60 mm to approximately 120 mm in length. Exemplary lengths for the bar include: at least 40 mm, at least 50 mm, at least 60 mm, at least 70 mm, at least 80 mm, at least 90 mm, at least 100 mm, at least 110 mm, at least 120 mm, at least 130 mm, at least 140 mm, at least 150 mm, and at least 160 mm.

[0299] In further examples, the bar may be approximately 4 mm to approximately 160 mm, approximately 5 mm to approximately 150 mm, approximately 6 mm to approximately 120 mm, or approximately 10 mm to approximately 100 mm in width. Exemplary widths for the bar include: at least 4 mm, at least 5 mm, at least 6 mm, at least 7 mm, at least 8 mm, at least 9 mm, at least 10 mm, at least 15 mm, at least 20 mm, at least 50 mm, at least 100 mm, at least 120 mm, at least 150 mm, at least 200 mm, and at least 250 mm.

[0300] In further examples, the bar may be approximately 3 mm to approximately 170 mm, approximately 4 mm to approximately 160 mm, approximately 5 mm to approximately 150 mm, approximately 6 mm to approximately 120 mm, orapproximately 10 mm to approximately 100 mm in height. Exemplary heights for the bar include: at least 3 mm, at least 4 mm, at least 5 mm, at least 6 mm, at least 7 mm, at least 8 mm, at least 9 mm, at least 10 mm, at least 15 mm, at least 20 mm, at least 50 mm, at least 100 mm, at least 120 mm, at least 150 mm, at least 160 mm, and at least 170 mm. Other sizes may also be suitable. It will be understood that device is not limited to any particular size or type of bar to be used.

[0301] In its closed orientation, the bar may sit secured against the section of hair, and press inwards towards the flap component and the support body underneath (e.g., wishbone configuration) the flap component. To assist with distribution of the hair treatment underneath the bar (e.g., where the section of hair contacts the bar), different features may be utilised. As an exemplification, the head of the bar may penetrate a washer (e.g., retention washer) and / or a clip (e.g., annular clip). In addition, it is possible for the washer and / or the clip to be countersunk into the upper side / outward facing side of the supporting means. Because the washer and / or clip sits in a countersunk position, this allows the hair composition to pool into the countersunk washer and / or clip and under the bar. This in turn allows the hair composition to saturate the hair positioned beneath the bar, which would otherwise have reduced contact with the hair composition.

[0302] As another example, the underside of the bar can include one or more projections and / or grooves, e.g., one or more corrugations, blades, prongs, rims, tines, or other means, to contact the hair while at the same time maximising contact between the hair and the hair composition. As a further example, the underside of the bar may be provided in a prism configuration or in essentially a prism configuration, such that points of the prism sit in contact with the hair and the contact between the hair and the hair composition is maximised.

[0303] In certain aspects, where the tensioning means includes a bar, the bar may comprise a stiffer textured material on its upper side (e.g., solid ridging). The bar may also comprise a softer textured material (e.g., pliable thermoplastic elastomer material) on its underside. The texture may include, for example, one or more projections and / or one or more grooves. Specifically noted are one or more corrugations. The strands of hair may be captured by these texture(s) and / or material(s). The texture(s) may assistwith keeping tension on the section of hair whilst allowing the composition to saturate the strands of hair that are held in place under the bar. For example, a lightener and a developer can react during a colouring process causing the mixture to swell and fill the spaces created by the texture(s) under the bar.

[0304] As an additional example, the bar may be designed to include a distal portion that is localised away from the washer and / or clip, such distal portion being angled or curved upwards (e.g., an upwards flick). This can assist the user in tucking the section of hair underneath the bar. The tensioning means (e.g., comprising a bar) may be positioned at or proximal to a bottom portion of the flap component / support body. The tensioning means may be positioned off centre relative to the flap component / support body, e.g., at a right hand side or left hand side of the flap component / support body.

[0305] In certain aspects, it may be desirable to lock the one or more tensioning means in place, to further secure the hair to the flap component. For example, tensioning means may be pressed to achieve a locked position, and may be pulled on to achieve an unlocked position. As an alternative to this, a tensioning means may engage with one or more locking mechanisms, and thereby be locked and unlocked through use of the one or more locking mechanisms. The one or more locking mechanism may include, for example, pins, buttons, knobs, latches (e.g., thumb turns), levers, and any combination thereof. It will be understood that one or more secondary tensioning means (e.g., protuberance(s)) can be utilised for longer sections of hair. For example, a longer section of hair can be wrapped around the secondary tensioning means before being wrapped around the primary tensioning means (which can be locked and unlocked). In this way, a longer section of hair may be arranged neatly on the flap component.

[0306] The tensioning means for the flap component can be highly beneficial for the user. It allows the user to hold the section in hair in place while freeing up the users fingers. With foils, the user typically uses a thumb or other finger to hold the hair onto the foil, i.e., gather into a “v” shape. The tensioning means keeps this “v” shape, but without the user needing to keep one or more fingers in place. Moreover, the tensioning means can be used to keep the hair positioned in initial stages and throughout the entire treatment process. The tensioning means may be optimised for ease of use, ease ofcleaning, and / or ease of manufacture. Different shapes and options may be utilised for the tensioning means, e.g., open and closed positions, one or more transparent portions, and / or hub and spoke configurations to allow hair to be treated while being trapped at a tension point.

[0307] As one option, when pushed into its locked position, at least a portion of the tensioning means can be utilised to compress against the flap component and hair and hold the hair in position. As one option, the underside of at least a portion of the tensioning means may include a sticky and / or pliable polymer or similar substance to aid in the holding of the hair. As one option, a hub and each of the spokes may be utilised as connection points. The hair composition may be applied whilst the tensioning means is in a locked position in between the spokes. As one option, when the tensioning means is in an unlocked position, this can be utilised to assist in releasing the hair and also provide ease of cleaning under the tensioning means. As one option, when the user wishes to disengage the device of this disclosure, the device can be lifted from its tail end. In this way, the tightness of the tensioning means may be lessened. As one option, the user may disengage the tensioning means by disengaging a locking mechanism on the underside (i.e., scalp facing side) of the flap component, and in this way and the hair may be released.

[0308] In specific aspects, the tensioning means may take advantage of the hair’s cuticle, which is comprised of small scales pointing downward. In this way, the tensioning means can facilitate attachment of the hair (going in the direction of the cuticle), but can work against release of the hair (going against the direction of the cuticle). When the user wishes to remove the hair from the tension means, it is possible to pull the device on an angle and this releases the tension points. For example, sharks teeth tread may be utilised on the flap component to get under the cuticle and help to hold the hair in place. When sharks teeth tread is applied on an angle (e.g., about 30° to about 45° angle), then it is possible to facilitate removal of the flap component by tilting the flap component to approximately the tread angle (e.g., about 30° to about 45° angle), and pulling on the flap component to assist with release. This tilting and pulling action can be performed along with releasing / unlocking the one or more tensioning means, if such is / are being used.

[0309] As indicated above, the clip component may be provided individually, or as a paired set (e.g., top and bottom clip components assembled together). In the same way, the flap components may be provided individually, or as a paired set (e.g., top and bottom flap components assembled together). For example, a device comprising preconnected and paired clip components and pre-connected and paired flap components can be provided to allow clamping onto a section of hair. As an alternative, the user can connect the pairs of clip components, and can also connect the pairs of pairs of flap components to allow clamping and holding a section of hair. It is also possible to provide a clip component and a flap component as one integrated piece, i.e., a flap component having a built in clip. It is further possible to provide pairs of integrated componentry, i.e., a pair of flap components with each having a built in clip.

[0310] In addition, it is possible to forgo the clip component / paired clip componentry and rely on the flap component having certain features, for example, one or more of: engagement or positioning means (e.g., one or more teeth or other projections), tensioning means (e.g., one or more protuberances), operational features (e.g., one or more supporting arms, supporting body, and / or bracing elements), and / or contouring (e.g., curvature to generally follow the scalp), as described herein. Thus, the one or more aspects, features, and advantages of the clip component noted herein may be incorporated into the flap component.

[0311] Once the section of hair is held in place by the tensioning means, the hair composition may be applied. For processing, the flap component can be folded or rolled onto itself, or a second flap component can be placed on top of the first flap component (e.g., sandwiching). In certain aspects, one or more surfaces of the flap component are adapted to allow easy and neat application of the composition. For example, the surface of the flap component that holds the section of hair can be essentially flat, smooth, and firm. This assists the colourist in painting or brushing the composition onto the hair, and ensures easy and even coverage. Ideally, the surface is not slippery as to make the composition drip or run during application. At the same time, the flap component may include a portion having one or more textures, e.g., elevated features such as treads, scales, corrugations, or other means. The flap component may include a portion having one or more sticky substances or materials, e.g., tacky components, such as one or moreviscoelastics, and / or friction forming components, such as one or more frictional polymers. These one or more textures and / or sticky substances / materials may assist in holding the hair in place. In specific aspects, the one or more textures and / or sticky substances / materials may be on the underside of the one or more tensioning means on the flap component.

[0312] In some circumstances, it may be helpful to include one or more raised features on the surface of a flap component. This can include, for example, one or more protrusions to help prevent drips or runs. In particular, this can help to prevent the composition from leaking from the flap component, and / or help to prevent overshooting, i.e., to prevent the user from applying the composition to the scalp. As exemplifications, the flap component may include one or more lips, ribs, ridges, rims, shoulders, teeth, guard rails, or other means. For example, a moulded guard rail may extend along left and / or right portions of the flap component, and / or bottom portion of the flap component, to inhibit leaking of the composition onto the scalp or neighbouring regions of hair. In certain aspects, it may be possible to align the left and right guard rails on the bottom portion of the flap component with the left and right guard rails on the top portion of the flap component, to allow folding and securing of the flap component on itself. This is particularly useful where the flap component is used without the clip component / paired clip componentry. In this way, the guard rails may provide a means for securing the top and bottom portions of the flap component together, but other securement means may also be utilised.

[0313] It is also possible to include one or more ingresses in the flap component (e.g., one or more channels, dimples, slots, ruts, or other means) to assist with holding and colouring longer hair. In addition, as noted above, the flap component may include one or more reservoirs for holding a hair composition, which can be transitioned onto the hair, e.g., by pressing, sliding, squeezing action. The reservoir may be refillable and / or recyclable.

[0314] The flap component (and or the clip component) may also be designed to include a heat sensor, time sensor, or other means for sensing relevant parameters. The sensing means may in turn communicate with one or more electronic devices, e.g., smartwatches, mobile phones, tablets, personal computers, etc. Optionally, the data may be transmitted to one or more databases for storage. For example, databases may be employed to store client information and specific treatment details. It is also possible for a user to determine sufficient hair treatment by visual confirmation (e.g., for colour treatment) or tactile confirmation (e.g., for conditioning treatment). For example, where a flap component is at least partly transparent a user may view the treatment results through the flap component. Alternatively, the flap component can be opened up by the user (e.g., unrolled, unfolded, peeled away, etc) to view the treatment results.

[0315] In other aspects, the design of the flap component allows easier manipulation or folding. For example, where paired flap components are used, the top most flap can be a construction that is lighter weight and / or more flexible than the bottom most flap. At the same time, it is helpful for the construction to have some stiffness, to ensure that the top most flap can close over the bottom most flap. As a further example, where individual flap components are used (single flap folded or rolled back on itself), the construction will tend to be lighter weight and / or more flexible. In addition, these components may include a “fold line” or similar construction, so that the fold occurs in the same region with each use. Ideally, this region is sufficiently durable so as to stand up to repeated folding and unfolding.

[0316] Notably, where paired flap components are sandwiched together over a section of hair, this will assist in heating up the hair and accelerating any treatment on the hair. Similarly, where a flap component is folded onto itself or rolled onto itself so as to cover the section of hair, this will assist in heating up the hair and accelerating any treatment on the hair. It will be understood that hair cuticles will be able to open in a heated environment, and will be more receptive to treatment in this environment. In addition, hair compositions will tend to work faster and / or more completely where heat is increased. Therefore, the one or more flap components can be utilised to provide highly efficient and highly effective treatments.Materials

[0317] Various materials, including certain mixed materials and other combinations of materials (e.g., layered, coated, etc) may be utilised for the flapcomponent and its associated features. The material(s) utilised will be capable of withstanding harsh chemical environments, different pH ranges, and repeated washing cycles. Noted are materials with the characteristics of being light-weight, flexible, durable, sterilisable, and resistant to chemicals (e.g., resistance to staining and / or surface damage). Noted also are the characteristics of being receptive to hair compositions, easy to fold, and having excellent tack, good thermal conductivity and stability, and sufficient adhesion / cohesion under finger pressure. Particularly noted are surface chemistries providing excellent tack after each application, but also allowing repeated and rapid detachment. For example, materials that mimic the surface physiochemical properties of gecko feet are specifically encompassed. Ideally, the one or more materials will also be capable of retaining heat for the reasons noted herein.

[0318] As various exemplifications, the materials used may be natural, nonnatural, or combinations thereof. Nonlimiting examples include plastics, elastomers, resins, metals, and any combination of these. Noted are materials that form a malleable surface, and can be manipulated to cover the section of hair on the flap component. Noted are componentry constructed from one or more polymers, such as silicone, rubber, polyisoprene, polybutadiene, ethylene propylene, or polyurethane. Other polymer and non-polymer materials may also be suitable.

[0319] Particularly noted are silicone rubbers, for example, PDMS (polydimethylsiloxane) and LSR (liquid silicone rubber), and thermoplastic elastomers, including elastomeric alloys, polyamides, copolyesters, olefins, polyolefin blends, block copolymers, and thermoplastic styrenic elastomers, such as SEBS (styrene-ethylene- butylene-styrene). Commercially available silicone rubber materials include, for example, ELASTOSIL® films, and SILPURAN® films (Wacker Chemie AG). Commercial sources for SEBS include KRATON™ G products (Kraton™ Corporation), SEPTON™ series products (Kuraray Company Ltd), Calprene® products (Dynasol Group), and DYNARON™ products (JSR Micro NV), amongst others. Noted suppliers include, for example, Prochase Enterprise Co Ltd, Joss Elastomer & Chemicals, Aurora Plastics (e.g., AuroraFlex™ SBS and SEBS), and Symplast (e.g., symflex®S SEBS). Other commercial thermoplastic elastomers are available as HYTREL® products (DuPont Chemicals Company). Thermoplastic nanofibre products are also commerciallyavailable, for example, interlaminar reinforcement veils such as XantuLayr® (Nanolayr Ltd).

[0320] Also noted are rubber type elastomers, for example, NBR (nitrilebutadiene rubber), CSM (chloro sulfonated rubber), CSM-PE (Chlorosulfonated polyethylene rubber), EPDM (ethylene propylene diene rubber), ECO (epichlorohydrin rubber), EPM (ethylene propylene rubber), FVMQ (fluorosilicone rubber), HSBR (hydrogenated styrene -butadiene rubber), IR (isoprene rubber), IIR (isobutyleneisoprene rubber), SBR (styrene -butadiene rubber), neoprene, and natural rubber (NR). Of additional interest are ABS (acrylonitrile-butadiene-styrene), styrene- ethylene / propylene-styrene (SEPS), SBC (styrene block copolymer), SBS (styrene- butadiene-styrene), and SIS (styrene-isoprene-styrene). Of further interest are TPU (thermoplastic polyurethane), TPV (thermoplastic vulcanizate), thermoset silicone, EVA (ethylene- vinyl acetate), LDPE (low density polyethylene), HDPE (high density polyethylene), and PP (polypropylene).

[0321] Various mixtures and other combinations of materials (e.g., layering, coating, etc) may be utilised. For example, thermoplastic elastomers, including SEBS or others, may be mixed together with one or more of: other polymers, oils, fillers, and any combination thereof. Particular fillers include, but are not limited to: carbon black, multilayer graphene, multi-walled carbon nanotubes, mineral fillers including silica (e.g., nano silica), silicon nitride (SisN4), silicon carbide (SiCw), calcium carbonate, alumina trihydrate, hybrid alumina, aluminium nitride (AIN), aluminium oxide (AI2O3), mineral mica, boron nitride, metal oxides, hydroxides, etc.

[0322] The materials, mixtures, and combinations may be utilised for the flap component itself, and / or at least one feature associated with the flap component, for example, the one or more tensioning means, the one or more locking mechanism, the one or more supporting means, the one or more raised features, the one or more impedance means, the one or more reservoirs, the one or more barrier means, or any combination of these. For example, the one or more tensioning means may include at least one thermoplastic elastomer such as SEBS.

[0323] In certain aspects, the SEBS material that is utilised may have styrene content of at least 10%, at least 11%, at least 12%, at least 13%, at least 14%, at least 15%, at least 16%, at least 17%, at least 18%, at least 19%, at least 20%, at least 25%, at least 30%, at least 35%, at least 40%, at least 45%, at least 50%, at least 55%, at least 60%, at least 65%, at least 70%, or at least 75% (wt%). Exemplary ranges for styrene content include, e.g., about 10% to about 15%, or about 15% to about 20%, or about 20% to about 25%, or about 25% to about 30%, or about 30% to about 35%, or about 35% to about 40%, or about 40% to about 45%, or about 45% to about 50%, or about 50% to about 55%, or about 55% to about 60%, or about 60% to about 65%, or about 65% to about 70%, or about 70% to about 75% (wt%).

[0324] In specific examples, flap components may have a length of approximately 200 mm to approximately 500 mm, or approximately 250 mm to approximately 450 mm, or approximately 280 mm to approximately 380 mm, or approximately 270 mm to approximately 350 mm. Exemplary lengths for the flap components include: at least 200 mm, at least 220 mm, at least 240 mm, at least 250 mm, at least 260 mm, at least 270 mm, at least 280 mm, at least 290 mm, at least 300 mm, at least 320 mm, at least 340 mm, at least 350 mm, at least 360 mm, at least 370 mm, at least 380 mm, at least 390 mm, and at least 400 mm.

[0325] Where two flap components are used in conjunction (e.g., with a sandwiching arrangement), each flap component may have a length of approximately 100 mm to approximately 450 mm, approximately 120 mm to approximately 420 mm, or approximately 140 mm to approximately 400 mm, or approximately 160 mm to approximately 380 mm, or approximately 170 mm to approximately 370 mm, or approximately 180 mm to approximately 360 mm, or approximately 175 mm to approximately 350 mm. Exemplary lengths for each individual flap component include: at least 100 mm, at least 120 mm, at least 140 mm, at least 150 mm, at least 160 mm, at least 170 mm, at least 175 mm, at least 180 mm, at least 190 mm, at least 200 mm, at least 220 mm, at least 240 mm, at least 250 mm, at least 260 mm, at least 270 mm, at least 280 mm, at least 290 mm, at least 300 mm, at least 320 mm, at least 340 mm, at least 350 mm, at least 360 mm, at least 380 mm, at least 400 mm, at least 420 mm, at least 440 mm, or at least 450 mm.

[0326] In further examples, flap components may have a width of approximately 40 mm to approximately 180 mm, approximately 60 mm to approximately 160 mm, 70 mm to approximately 150 mm, approximately 80 mm to approximately 140 mm, or approximately 90 mm to approximately 130 mm. Exemplary widths for the flap components include: at least 40 mm, at least 50 mm, at least 60 mm, at least 70 mm, at least 80 mm, at least 90 mm, at least 100 mm, at least 110 mm, at least 120 mm, at least 130 mm, at least 140 mm, at least 150 mm, at least 160 mm, at least 170 mm, at least 180 mm, at least 190 mm, and at least 200 mm.

[0327] The flap components may be any thickness. In particular examples, flap components may be 4 mm or less, 3.5 mm or less, 3 mm or less, 2.5 mm or less, 2 mm or less, 1.5 mm or less, 1 mm or less, 0.8 mm or less, 0.4 mm or less, 0.2 mm or less, or 0.1 mm or less. Exemplary ranges for thickness include: about 0.1 mm to about 0.4 mm, or about 0.1 mm to about 0.8 mm, or about 0.1 mm to about 1 mm, or about 0.1 mm to about 2 mm, or about 0.1 mm to about 4 mm, or about 0.2 mm to about 4 mm, or about 0.5 mm to about 4 mm, or about 1 mm to about 4 mm, or about 1.5 mm to about 4 mm, or about 2 mm to about 4 mm. Other sizes may also be suitable.

[0328] It will be understood that increasing the height of the flap component(s) that are provided will increase the length of hair to be supported / covered. Similarly, increasing the width of the flap component(s) that are provided will increase the width of hair to be supported / covered. In certain circumstances, reduced widths for the flap component(s) may be advantageous. In other circumstances, increased widths for the flap component(s) may be advantageous. In some cases, a flap component may have length(s) / width(s) comparable to the sizing of a standard pre-cut foil that is used in hair treatments. In other cases, a flap component may have length and / or width that is larger than standard pre-cut foil. In some situations, the paired flap components will be similar or essentially identical in size. In other situations, it is possible for the paired flap components to be different sizes. For example, the bottom most flap component that sits closest to the scalp can be provided as slightly larger in length or width than the top most flap component. This would provide additional protection for the scalp. The device is not limited to any particular size or type of flap component to be used.

[0329] In certain embodiments, the flap component may be provided in one or more colours, e.g., with colour coding, to assist in the colouring or highlighting / lowlighting process. For example, different sized flap components may be provided in different colours or shades. This could assist the colourist in identifying the correct flap component for a particular colouring / highlighting / lowlighting project. In one aspect, the flap component that supports the section of hair may be a dark colouration, for example, black, dark grey, dark blue, or dark purple. This provides a visual contrast for the colourist and shows clearly where the composition has been applied or where it needs to be applied.

[0330] Optionally, the flap component (or a portion of the flap component) may be provided as a transparent or essentially transparent material. Ideally, the transparent or essentially transparent material (e.g., a clear or essentially clear window) will allow visualisation of the hair processing. Transparency towards the folded portion of the flap is specifically noted. Also of interest is the area close to the scalp. For example, where there is paired flap componentry, the top most flap may be transparent or translucent, or may include a transparent or translucent window, to allow the colourist to confirm where colour has been applied and to visualise the extent of processing without lifting the top most flap, or otherwise disturbing the hair that is being processed. This is particularly helpful when multiple treatments are being applied to the hair, e.g., two or more colours being applied for the same customer.

[0331] Similarly, where individual flap components are used (single flap folded or rolled back on itself), it is possible for the bottom half of the flap component to be transparent or translucent, or to include a transparent or translucent window in the bottom half of the flap component. Then, when the flap component is folded back on itself and secured (such that the bottom half is now positioned over the top of the hair section), the colourist will be able to visualise the extent of processing without unfolding the flap, or otherwise disturbing the hair that is being processed.Manufacture and use of the device

[0332] The disclosed device may be used to optimise hair treatments and to prevent or reduce damage to the hair and scalp. The device is designed to provide forfaster application and treatment times. The device is designed to be simple to remove, and can be rinsed out the customer’s hair upon treatment completion. The device and its components are designed to be washed and reused numerous times, thereby reducing waste. Where the clip component is contoured to the shape of the scalp, this keeps colour and highlighting / lowlighting even and protects the scalp. The look of the device is clean, professional, and modern.

[0333] The clip components may be manufactured by any suitable means. Production may be from a natural or non-natural material, or any combination thereof. Particularly noted are plastic materials, metal materials, resin materials, and various combinations of these. The clip components may be bent or moulded to the appropriate shape and size, and / or may be modified by one or more of cutting, drilling, or coating, or other means. The clip components may then be assembled, e.g., paired and connected together, or may be provided individually.

[0334] In the same way, the flap components may be manufactured by any suitable means. Production may be from a natural or non-natural material, or any combination thereof. Particularly noted are plastic materials, elastomer materials, resin materials, and various combinations of these. The flap components may be sliced or moulded to the appropriate shape and size, and / or may be modified by one or more of cutting, drilling, or coating, or other means. The flap components may then be assembled, e.g., paired and connected to the cognate clip components, or may be provided individually. As noted above, the flap components may be designed for use without the clip components / paired clip componentry.

[0335] In one aspect, a kit may be provided which includes one or more of the clip components and / or one or more of the flap components. In one other aspect, the kit may include one or more assembled devices and / or one or more assembled componentry pairs, e.g., one or more pre-connected and paired clip components. The devices and / or components may be provided in one or more containers or packages in the kit. Additional items may also be provided with the kit, for example, one or more compositions for hair or one or more tools (e.g., combs, brushes, picks, applicators, or other means) for hair. Optionally, instructions may be provided with the kit, as well as any other containers(e.g., jars, bottles, envelopes, bags, sachets, sacks, pouches, or other means), labels, fasteners, or implements.

[0336] As one embodiment, a method of this disclosure comprises positioning a first clip component under a section of hair, positioning a second clip component over this section of hair, and clamping the first clip component and the second clip component together so as to hold the section of hair in place. This method can further comprise connecting the first clip component to a first flap component, and connecting the second clip component to a second flap component.

[0337] As one other embodiment, a method of this disclosure comprises positioning a first clip component under a section of hair, positioning a second clip component over this section of hair, and clamping the first clip component and the second clip component together so as to hold the section of hair in place, wherein the first clip component is connected to a first flap component, and the second clip component attached to a second flap component.

[0338] As another embodiment, the method comprises clamping a pair of clip components onto a section of hair, and then connecting each clip component to a flap component. According to this embodiment, the clip components are pre-connected and already paired.

[0339] As a further embodiment, the method comprises clamping a pair of clip components onto a section of hair, wherein each clip component is connected to a flap component. According to this embodiment, the clip components are already paired together and connected to each other and to the corresponding flap components. In this way, it is possible to pre-assemble the device before use.

[0340] As still a further embodiment, the method comprises positioning a first clip component under a section of hair, positioning a second clip component over this section of hair, and clamping the first clip component and the second clip component together so as to hold the section of hair in place, wherein the first clip component is connected to the backside of a flap component, and the second clip component is connected to the bottom end of the flap component.

[0341] As even a further embodiment, the method comprises positioning the flap component (that does not include a clip component or paired clip componentry) proximate to the scalp, adjacent to the scalp, or onto a section of hair (i.e., not adjacent to the scalp). For example, a plurality of projections (e.g., teeth, bulges, humps, jags, juts, ridges, or other means) may be lined along the leading edge of the flap component, and such may assist with positioning of the flap component. In addition, the hair may be secured and tensioned onto the flap component by one or more tensioning means (e.g., protuberance(s)) on the flap component. In certain aspects, the plurality of projections (e.g., teeth, bulges, humps, jags, juts, ridges, or other means) can work in conjunction with the one or more tensioning means (e.g., protuberance(s)) so as to position the device and secure the hair that is to be treated. In addition, the leading edge of the flap component may be deformed when put into position, so as to provide better engagement with the scalp and / or the section or hair.

[0342] In some cases, it will be helpful to put all of the necessary devices in place on the head before applying the composition. This ensures a more even processing result over the whole head (unlike foils, which are much slower to apply and necessarily progressive). However, it is also possible to add composition to one or more devices at different times, if desired. Where the barrier means is used with the flap components of the device, it is possible to release the composition onto the sections of hair very quickly, and provide what is effectively a coordinated application of the composition. Again, this assists with providing an even result.

[0343] Therefore, it can be advantageous to utilise devices where the flap components are pre-loaded with composition. This removes the need to paint or brush the composition onto each section of hair. As already noted, it is possible to utilise the barrier means to keep the composition from the hair until the desired contact time. In certain circumstances, it is possible to pre-load the flap components with a precursor composition that is not activated until addition of a specific compound or substance, or until removal of a barrier means. It is also possible to transition a composition from a reservoir in a flap component to the hair, e.g., by pressing, sliding, or squeezing action. It is further possible to activate the heat sensor, time sensor, or other means on the clip component and / or the flap component for sensing relevant parameters. It is then possibleto use the sensing means to communicate with one or more electronic devices, (e.g., smart watches, mobile phones, tablets, personal computers, or other means), and optionally to transmit data to one or more databases. These various approaches can provide for an even and consistent colour result.

[0344] In one aspect, the device disclosed herein may be used with a specially modified comb, brush, pick, applicator, or similar tool. For example, the tool may be specifically adapted to interact with the device or one or more components of the device. As noted above, a hexagonally configured tool (e.g., having an Allen key-shaped handle) may be used to engage with a hexagonally configured bore in the clip component. Other tool configurations may be utilised, e.g., rectangular, rounded, etc. As exemplifications, the tool handle may be composed of metal, plastic, or resin, or any combination of these.

[0345] The tool handle may also be adapted to allow parting and sectioning hair. For example, the handle may have a point or other projection. In one aspect, the head of the comb or brush, or other tool, is sized to be similar to or slightly wider than the flap component. This helps the colourist to obtain sections of hair that are suitable to fit the flap components. While this specification refers to colouring and highlighting / lowlighting compositions, in particular, it will be understood that the disclosed device and disclosed methods are not limited to use with these hair compositions. Other compositions of note include conditioning, repairing, protecting (e.g., heat protection), detoxifying, densifying, relaxing, smoothing, straightening, styling, curling, wave applying, moisture applying, shine applying, and gloss applying compositions. A combination of compositions may be utilised.

[0346] It can be advantageous for the materials of the device to be recyclable. For example, component parts comprising thermoplastic elastomers (including styrenic elastomers such as SEBS, SBS, SIS, etc) may be melted down and remoulded into new replacement parts. The ability to melt down and reform the component parts for the device minimises waste and the costs associated with waste.Specific exemplifications of the device and components

[0347] Non-limiting exemplifications of the device and components are described as follows.

[0348] Referring to the drawing of Figure 1, this provides a front view of one embodiment of the device, which is depicted in an open position. In this illustration, the device 10 is shown as having a pair of clip components 20a and 20b (top and bottom, assembled together), and a pair of flap components 25a and 25b (top and bottom, assembled together). The top clip component 20a is reversibly connected with the top flap 25a component, while the bottom clip 20b component is reversibly connected with the bottom flap component 25b. The clip components 20a and 20b each have a plurality of projections (e.g., plurality of teeth, 22a and 22b) for engaging with the section of hair (H). The device 10 is also shown as having a releasing means (e.g., push button, 21) for transitioning the device from the closed position to the open position. In addition, the device 10 is shown as having a barrier means (e.g., pull tab, 26) which prevents the hair composition (C) from contacting the hair until the allotted time. That is, the composition (C) is above the barrier means and below the top flap component.

[0349] Referring to the drawing of Figure 2, this provides a perspective view (left side) of one embodiment of the device, which is depicted in an open position. In this illustration, the device 10 is again shown as having a pair of clip components 20a and 20b (top and bottom, assembled together), and a pair of flap components 25a and 25b (top and bottom, assembled together). The top clip component 20a is reversibly connected with the top flap 25a component, while the bottom clip 20b component is reversibly connected with the bottom flap component 25b. The section of hair (H) is shown as projecting between the connected pair of clip components, 20a and 20b, and engaging with the corresponding plurality of projections emanating from the pair of clip components. The barrier means (e.g., pull tab, 26) holds the composition (C) against the top flap component 25a, and away from the section of hair (H). That is, the composition (C) is above the barrier means and below the top flap component.

[0350] Referring to the drawing of Figure 3, this provides a perspective view (left side) of one embodiment of the device, which is depicted in a closed position. In this illustration, only the top clip component 20a and the top flap component 25a are shown. Although not depicted, the bottom clip component will be directly beneath the top clip component, while the bottom flap component will be directly beneath the top flap component. As shown here, the barrier means (e.g., pull tab, 26) is pulled out of thedevice, allowing the composition to contact the hair within the device (not shown). The composition and hair are then sandwiched between the top flap component 25a and the bottom flap component 25b (not shown), and this allows processing to take place. The portion of hair (H) projecting out from the device is not contacted with the composition, and is thereby protected from processing.

[0351] Referring to the drawings of Figures 4A-4C, these provide perspective views (right side) of particular embodiments of the paired clip componentry and a flap component. Figure 4A illustrates the paired clip componentry (190) in an open position, while Figure 4B illustrates the paired clip componentry (190) in a closed position. As shown here, the paired clip componentry (190) includes a top clip component (201a) and a bottom clip component (201b). The paired clip componentry (190) further includes a hinging means (240) and a releasing means (230) which together allow the paired clip componentry to be opened to receive a section of hair. The releasing means (230) is shown here as a lever. The paired clip componentry (190) also includes optional securing means (203), e.g., magnetic elements, to assist in keeping the componentry in a closed position. In Figure 4C, the flap component (180) includes an optional transparent section (252), and an optional edging (253) to enhance engagement with the bottom clip component (201b). In turn, the bottom clip component (201b) includes an optional bench portion (202) to enhance engagement with the flap component (180). In these exemplifications, only a single flap component is shown, e.g., a bottom flap component, but other exemplifications may include more than one flap component, e.g., a bottom flap component and a top flap component.

[0352] Referring to the drawings of Figures 5A-5C, these provide perspective views (right side) of particular embodiments of the device. Figure 5A illustrates the device (100) having the paired clip componentry an open position, while Figure 5B and 5C illustrate the device (100) having the paired clip componentry in a closed position. As in Figures 4A and 4B, the paired clip componentry (190) includes a top clip component (201a) and a bottom clip component (201b). The paired clip componentry (190) further includes a hinging means (not shown) and a releasing means (230) which allow the componentry to transition to an open position. In Figures 5 A and 5B, the bottom flap component (251b) is shown as connected to the bottom clip component. InFigure 5C, the bottom flap component is shown as being folded back on itself, this conformation providing enhanced holding power and treatment for a section of hair (H) that is positioned on the flap component. In these exemplifications, only a single flap component is shown, e.g., a bottom flap component, but other exemplifications may include more than one flap component, e.g., a bottom flap component and a top flap component.

[0353] Referring to the drawings of Figures 6A and 6B, these provide perspective views (right side) of particular embodiments of paired clip componentry and a flap component. Figure 6A illustrates the flap component (180) as having a barrier means (254) that can be removed to allow the section of hair to be contacted with a composition (C). A bottom flap component is illustrated here. Figure 6B illustrates the flap component (180) being removed from the paired clip componentry (190). This can be done, for example, upon completion of treatment. As in Figures 4A and 4B, the paired clip componentry (190) includes a top clip component (201a) and a bottom clip component (201b). The paired clip componentry (190) further includes a hinging means (240) and a releasing means (230) which allow the componentry to transition to an open position. In these exemplifications, only a single flap component is shown, e.g., a bottom flap component, but other exemplifications may include more than one flap component, e.g., a bottom flap component and a top flap component.

[0354] Referring to the drawings of Figures 7A and 7B, these provide perspective views (right side) of particular embodiments of a device positioned on a head of hair. Initially, the subject’s hair can be prepared for treatment and a section of hair can be pulled towards the user. Figure 7A illustrates an embodiment whereby the section of hair (H) is pulled under tension and the top clip component (201a) and the bottom clip component (201b) of the paired clip componentry are positioned in proximity to the subject’s scalp. The section of hair (H) is then positioned on the bottom flap component (251a), and the paired clip componentry can then be clamped onto the hair. The user may also connect a top flap component, if this is desired. Figure 7B illustrates an alternative embodiment, whereby the paired clip componentry is be clamped onto the section of hair (H), and the bottom flap component (251a) is connected to the bottomclamp component (not shown) after the clamping has taken place. The user may also connect a top flap component, if this is desired.

[0355] Referring to the drawings of Figures 8 A and 8B, these provide perspective views (right side) of particular embodiments of a device positioned on a head of hair. As with the previous embodiments, the subject’s hair can be prepared for treatment and a section of hair can be pulled towards the user. Figure 8A illustrates an embodiment whereby the section of hair (H) is pulled under tension and the paired clip componentry are positioned in proximity to the subject’s scalp. The section of hair (H) is then positioned on the bottom flap component (251a), and the paired clip componentry is then be clamped onto the hair. The clamped configuration is illustrated in Figure 8B. The user may also connect a top flap component, if this is desired.

[0356] Referring to the drawings of Figures 9A and 9B, these provide perspective views (right side) of particular embodiments of a device positioned on a head of hair. Figure 9A illustrates an embodiment where composition (C) is contacted to the section of hair (H) that is positioned on the bottom flap component (251b). Once the composition is added, the user may also connect a top flap component, if this is desired. Figure 9B illustrates an embodiment where the bottom flap component is folded back on itself, this conformation providing enhanced holding power and treatment for a section of hair (H) that is positioned on the bottom flap component (251b). The user may choose to use this conformation for the bottom flap component in lieu of adding top flap component.

[0357] Referring to the drawings of Figures 10A-10C, these provide perspective views of particular embodiments the paired clip componentry in place on a head of hair. Figure 10A illustrates paired clip componentry (190) arrayed for radial latitudinal treatment, e.g., spanning over the top of the head.

[0370] Figure 19A illustrates the underside of a support body (711) and the underside of the support arms (710), which face the scalp. As shown here, the supporting arms (710) and the support body (711) together make a Y formation. Shown also are the openings (732) in the support body and the openings (742) in the support arms. The openings (732) in the support body assist in reducing the overall weight of the device. The openings (742) in the support arms provide points for attaching a positioning means(e.g., comprising a plurality of teeth). The tensioning means includes a bar, which assists in holding a section of hair in place on the flap component. In this particular embodiment, the bar is positioned in its locked arrangement, whereby the head (782) of the bar protrudes from the underside of the support body (711). The bar is illustrated more fully in Figures 19B-19D, described below.

[0371] Figure 19B illustrates the outward facing side of a support body (711) and support arms (710), which face the away from the scalp. Shown again are the openings (732) in the support body and the openings (742) in the support arms. The retention washer (722) is shown here as being countersunk into the outward face of the support body (711). The tensioning means includes a bar (702). In this embodiment, the bar (702) assists in holding a section of hair in place on the flap component (hair not depicted). The bar (702) is illustrated here in its locked position, i.e., pressed against the section of hair (hair not depicted).

[0372] Figure 19C illustrates the outward facing side of a device, viewed from its left side. In this embodiment, it is easy to see the arcuate or essentially arcuate orientation of the device in both vertical and horizontal planes (see dashed arrows). Shown are the support body (711) and the left support arm (710). Shown also are the openings (732) in the support body. The retention washer (722) is countersunk into the outward facing side of the support body (711). The retention washer (722) as shown here assists in holding the flap component (750) in place. Its countersinking also facilitates contact between the hair composition and the hair that is held by the tensioning means (hair not depicted). As noted for this embodiment, the tensioning means includes a bar (702), which assists in holding a section of hair in place on the flap component (750; hair not depicted). Here, the tensioning means is shown in its locked position, with the bar (702) pressed against the section of hair (hair not depicted). The positioning means is also shown; this includes a plurality of projections (701; teeth). As illustrated, the projections are arranged along the leading edge and are graded between 130 degrees (on ends) and 150 degrees (in middle) relative to the flap component. Shown as well are the bracing elements (713; fingers), which sit under the flap component (750) and span between the left and right sides of the leading edge.

[0373] Figure 19D shows a portion of a tensioning means of the device. As depicted here, the tensioning means includes a bar (702). The underside of the bar (702) may optionally include one or more areas containing sticky or pliable material(s) (762) and / or one or more areas containing texture(s) (763; corrugations). The material(s) and / or texture(s) can be used to assist in holding the section of hair in place against the flap component. The head (782) of the bar is also shown. To lock the tensioning means, the bar is pressed against the section of hair; this pushes the head (782) of the bar through to the underside of the support body. To unlock the tensioning means, the head (782) of the bar is pressed upwards and away from the scalp; this releases the bar from the section of hair. This is described in more detail herein.

[0374] Figure 20 shows the results from the bench trials (see below). The results show that the disclosed device provided significantly faster colouring results (the lifting of hair pigment) than foils. The hair processing carried out in foils was 10-12 minutes slower than the hair processing carried out in the device described herein.

[0375] Figure 21 provides a photograph of the device as used in the bench trials. As shown here, the device is positioned into place on the head of hair and a section of hair is tensioned onto the device. Shown in particular is the tensioning means which includes a bar (702) having a head portion (782). In its locked position, the bar (702) is pressed against the section of hair (H) and holds the section of hair against the flap component (750). Once the hair composition is applied to the section of hair, the flap component (750) is folded onto itself and thereby enfolds the section of hair (H). Shown also are the support arms (710) and the support body (711) of the device, which sit underneath the flap component (750).Example 1: Initial product testing - part 1

[0376] Manufacture: For manufacture of the flap component, styrene-ethylene- butylene-styrene (SEBS) film was obtained as styrene block copolymer thermoplastic elastomer, extruded and slit. The SEBS film was translucent, elastic, and tacky, with a smooth finish. The film was provided in sheets 24 cm wide and 50 meters long, with 0.2mm thickness. These sheets were cut to an essentially rectangular shape, approximately 9 cm wide and 27 cm long.

[0377] Methodology: Nineteen stylists trialled the device (HYLO). Fourteen of these used the product regularly enough to understand the HYLO product and how it worked. To start, each stylist was given a short training session by an educator to overview functional and practical elements of the HYLO product.

[0378] Over the course of the trials, the HYLOs were used on a range of hair types (blonde, dark, thin, thick, small / large heads) and for achieving a range of treatments (colour, retouch, root to tip). Full head and half head colourings were performed. A qualitative researcher was engaged to prepare questions for the stylists and to observe the stylists while they worked. Eight stylists were observed over a three hour period while working on 4 clients, and were afterwards asked questions.

[0379] Results: The HYLO product appealed to the stylists questioned. Unprompted, three of the stylists said that they would switch to using the HYLO in its current form if it were commercially available. One of the stylists who loved the product and was particularly creative with it, asked to continue to use the product after the trial.

[0380] Conclusions: The following were perceived benefits (unprompted), as experienced by, and verbalised by, the trial participants:Example 2: Initial product testing - part 2

[0381] Aim: To assess the speed and consistency of lifting colour from hair using the HYLO product.

[0382] Background: During the first testing of the HYLO product (Example 1), more than half of the stylists commented that the HYLO product was lifting colour faster than foil. This was particularly noted when the station (where foil was being applied) was adjacent to the air conditioning unit. One stylist commented that foil can take up to 30 minutes longer to lift when the client is situated at that station. The educator said that the HYLO lifted colour faster than foil in a normal environment even when the client was under the air conditioning unit.

[0383] In addition to this, several stylists commented that they were getting a higher quality colour result with the HYLO product than they had with foil. Words used by stylists to describe this quality were “consistent” and “smooth”. One commented that he was getting a colour result like he would expect the scientists in Germany would be getting when they are testing products in a lab.

[0384] Methodology: On a clean table, plastic mats were laid out. Eight mats included pre-cut foil (EZ classics). One mat included a HYLO device. Each of the eight mats with foil included a card stating the number of minutes difference between opening the HYLO after processing and opening the foil after processing (the HYLO being opened before the foil). This included time differences of: 0 minutes, 2 minutes, 4 minutes, 6 minutes, 8 minutes, 10 minutes, 12 minutes, and 14 minutes. The precut foils and HYLO were approximately the same size and weight.

[0385] Prior to the experiment, the air conditioning was used to lower the temperature of the room to approximate the temperature of the average salon, i.e., between 22°C and 24°C. The room temperature achieved was 25 °C. The ducts for the air conditioning were located well away from the colouring station. To assess the results, a senior colouring educator / experienced colourist was employed. Oro Therapy Gold Activator 6% was utilised as the developer. De Lorenzo NOVALITE dust free powder lightener was utilised as the bleaching agent. These were standard salon products and the components were mixed as would normally be mixed in the salon, i.e., two parts developer to one part lightener. The lightener was allowed to remain active until it was washed off.

[0386] The hair samples were cut from a mannequin with straight human hair. The educator cut sections of hair that were all the same starting colour. Approximately the same number of stands of hair were cut. A bundle was sellotaped to each piece of the pre-cut foil and to the HYLO. The lightener and developer were mixed thoroughly and then applied to the hair on the HYLO and to the hair on each foil. The hair samples were folded into the HYLO or into the foils in a methodical swift sequence. The same amount of the developer / lighter mixture was applied to each of the cut sections of hair. The foil was folded in half in accordance with standard techniques for hair on the crownof the head. Each foil was patted down to ensure good contact between the hair and the mixture. After 31 minutes of processing the “same time” foil and HYLO were opened (0 minutes difference), and the mixture was washed off the hair using warm water. The next foil was opened at 33 minutes (2 minutes difference) and then washed. This procedure was repeated until the last foil was opened at 45 minutes (14 minutes difference). The hair samples were fully dried.

[0387] Results: The educator noticed the HYLO sample processing quicker than would be normally expected. Once washed and dried, the educator assessed the HYLO sample in comparison to the foil samples and noted significant evenness and consistency from the HYLO: “It has depth and consistency from start of application to the end / consistency of shade”. It was assessed to be a quality result. The educator further noted that the foil required 8 to 12 minutes longer (39 to 43 minutes of processing) to achieve the same colouring result as the HYLO (31 minutes of processing). See Figure 20. When the foil samples with shorter processing were assessed (31 to 37 minutes), these had not lifted to the same extent as the HYLO (31 minutes).

[0388] The aim is to repeat these experiments with test subjects. It is noted that the speed and consistency of processing is enhanced when performed on a human head. Without wishing to be bound by theory, it is believed that the heat of the client’s head warms up the hair composition and causes it to react faster. This can be particularly true closer to the roots. It is also noted that steam lamps can also be used to gently heat the hair / hair composition and accelerate the process.
