[0021] The foregoing aspects and many associated advantages of the present invention will be more readily appreciated as they are better understood with reference to the detailed description that follows, when taken in conjunction with the accompanying drawings. Detailed description

[0022] The detailed description set forth above in relation to the accompanying drawings, where similar numbers refer to similar elements, is understood as a description of various embodiments of the disclosed subject matter and is not intended to represent the only embodiments. The embodiments described in the The disclosures presented herein are provided simply as examples or illustrations and should not necessarily be construed as being preferred or advantageous over other embodiments. The illustrative examples provided herein are not intended to be exhaustive or to limit the claimed subject matter to the specific forms disclosed.

[0023] This disclosure relates generally to hair coloring adapters and processes for dyeing alternating strands of hair using them. Hair coloring has been an important aspect of the cosmetic arts for thousands of years, with historical evidence of coloring hair using natural dyes dating back to ancient Egypt and Rome. Despite this history, the hair coloring process is well known to be messy and will frequently result in stains and damage to clothing, towels, furniture, and the like.

[0024] Existing systems for applying hair and scalp treatment formulas are widely used. For example, hair coloring kits are commonly used to change the appearance of hair color or to blend gray hair, among other uses. Many existing at-home hair coloring systems have several drawbacks, including difficulty of use, time-consuming application, uneven coverage, unpredictable results, and excessive mess.

[0025] Although there have been advances in at-home hair coloring for the entire head of hair, many challenges remain in creating textured and layered application patterns, such as those required for highlights or other non-uniform applications of hair dye. Traditionally, in such cases, consumers visit a hair salon to have a professional hair colorist apply alternating layers of hair dye. This often involves manually separating strands of hair, brushing them onto film sheets, and waiting a long time.

[0026] Consequently, there is a need for improved devices and processes that allow a subject to obtain a textured hair coloring style, either at home, in a hair salon, or in another suitable location, while minimizing application time and the mess created. The present disclosure addresses these needs and other long-unmet needs in art.

[0027] In one aspect, the present disclosure proposes a hair coloring adapter for a hair coloring device 100 (described in more detail herein with reference to [Fig. 1A] and [Fig. 1B]). In some embodiments, the hair coloring device 100 is an example of the formulation delivery system described in detail in US Patent Application Publication No. 18 / 060 258 A1, published on May 30, 2024. However, it should be understood that the hair coloring adapter of this disclosure can be used on any hair coloring device.

[0028] The hair coloring device 100 is configured to receive a formulation cartridge type 103 (including a cleaning cartridge of the same type). The hair coloring device 100 includes a reusable handle 106 made of ABS plastic or a similar rigid polymer or other material, and in some embodiments, it is an assembly formed of a plurality of shells configured to be joined together with fasteners such as snap fasteners, screws, or the like. The reusable handle 106 has a hollow, elongated gripping portion having a cartridge cavity 124 inside that is shaped and sized to receive the formulation cartridge type 103. In some embodiments, the cavity includes keying features that facilitate the correct insertion of the formulation cartridge type 103.For example, some embodiments include a cartridge interface 130 disposed in the opening and having a flat receiving surface which serves as an interface with a corresponding receiving surface of the formulation cartridge 103 when the latter is correctly inserted into the opening.

[0029] The reusable handle 106 houses a formulation dispensing assembly, in addition to a controller. The formulation dispensing assembly dispenses a formulation or cleaning liquid from the formulation cartridge 103 and includes a pump, fluid lines, a mixing chamber, and a reciprocating nozzle assembly with nozzles 116 extending from the front end of the reusable handle 106 between a plurality of optional spacing protrusions 120. The reciprocating nozzle assembly includes a plurality of ring nozzles that perform a back-and-forth reciprocating motion along a track of the reusable handle 106 while dispensing the formulation onto a user's skin or hair. In some embodiments, the subject is also the user of the hair coloring device.In some embodiments, the subject is different from the user of the hair coloring device. In some embodiments, the reciprocating nozzle assembly performs a reciprocating motion at a reciprocating motion amplitude of 7.0-12.0 mm (e.g., 8.0 mm-11.0 mm or 9.0-10.0 mm) and / or at a reciprocating motion frequency of 5.0 Hz-10.0 Hz (e.g., 6.0 Hz-9.0 Hz, 6.0 Hz-8.0 Hz), which are adjustable by the formulation routine module, the cleaning routine module, the user routine module, the manual adjustment module, or another module.

[0030] A control button 104 located on the reusable handle 106 and electrically connected to the controller activates features of the formulation-dispensing hair coloring device 100 described above. For example, in some embodiments, pressing the control button 104 activates features such as a standby / activation module stored in the controller, thereby switching the formulation-dispensing hair coloring device 100 from a standby state to an activation state. In some embodiments, pressing the control button 104 while a formulation cartridge is inserted into the reusable handle 106 activates a formulation routine module stored in the controller, thereby initiating a formulation routine.In some examples, the control button 104 can be used to initialize the device 100 or place the hair coloring device 100 into a state to perform certain functions, such as one or more of the following: calculating a mixing ratio of the components of the coloring formulation; entering a cleaning or purging mode; heating the formulation; collecting data from the formulation containers, such as the remaining volume, mixing ratios, color information, etc.; sending and receiving signals; analyzing data concerning user preferences; collecting data from sensors; providing a status indication to the user, such as the output power level, battery life, remaining formulation volume, sensor data, data connection information, etc.; and communicating with auxiliary equipment.In some embodiments, the control button 104 is capable of pressure-sensitive operation, such that applying higher pressure to the control button 104 causes a variable response, such as, for example, causing the formulation to flow more rapidly, the nozzles to move more rapidly, or the like. In some embodiments, various operating parameters can be controlled by the use of a smart device, such as a phone (as described in detail in US patent application No. 14 / 586,138).

[0031] In some embodiments, pressing the control button 104 while a cleaning cartridge is inserted into the reusable handle 106 activates a cleaning routine module stored in the controller, thereby initiating a cleaning routine. Visual indicators 126 (e.g., LEDs) arranged along the reusable handle 106 indicate one or more items from a remaining quantity of formulation or remaining battery life, for example, based on a dispensing time determined by the formulation routine module in the controller. Some embodiments include additional buttons and / or a different number of visual indicators 126 with different functionalities, and the The illustrated embodiment is not limiting. In some embodiments, the visual indicators 126 are a multi-segment LED, each segment corresponding to an equal proportion of the formulation remaining in the formulation cartridge.

[0032] The controller includes logic (stored in a data store thereof) which, when executed by a processor of the controller, causes a cartridge authentication interface 130 disposed in the reusable handle 106 (for example, an RFID reader) to read an encryption chip 128 on the formulation cartridge 103 in order to authenticate the formulation cartridge 103. The encryption chip 128 stores at least one of the following: a formulation cartridge 103, a formulation identification, an initial formulation quantity, a formulation expiration date, or a formulation production date.

[0033] The controller also includes logic which, when executed, causes the formulation delivery device to execute, on the basis of the authentication of the formulation cartridge 103, a formulation routine which dispenses a mixed formulation (of the first formulation and the second formulation) from the formulation cartridge 103 through the formulation distribution set.For example, the formulation delivery device authenticates the first and second formulations after (or upon) the insertion of a formulation cartridge into the reusable handle, then, in response to the pressing of a button on the reusable handle, executes a formulation routine which causes the formulation dispensing assembly to continuously or continuously mix the first and second formulations, and dispense them from the reciprocating nozzle assembly at one or more of the following predetermined device operating parameters as long as the button is pressed: a formulation flow rate, a reciprocating frequency, or a reciprocating amplitude.

[0034] In some embodiments, the controller also includes logic which, when executed, causes the formulation delivery device to execute, based on the authentication of a cleaning cartridge inserted into the reusable handles, a cleaning routine which dispenses a cleaning liquid through the formulation dispensing assembly.For example, the formulation dispensing device authenticates a cleaning cartridge inserted into the reusable handle, and then, in response to a button being pressed on the reusable handle, executes a cleaning routine that causes the formulation dispensing assembly to continuously dispense a cleaning liquid (e.g., water) from the reciprocating nozzle assembly at one or more of the following predetermined device operating parameters as long as the button is pressed: a cleaning liquid flow rate, a reciprocating motion frequency, or a reciprocating motion amplitude. In some modes. In realization, the cleaning fluid flow rate is higher than any formulation flow rate of one or more of the formulation routines stored in the controller, which has the advantage of efficiently rinsing the residual formulation from the formulation dispensing assembly.

[0035] In some embodiments, the formula delivery system includes a first formulation source storing a first liquid formulation. In some embodiments, the first liquid formulation has a dye charge of 0.05% to 5.5%. In some embodiments, the first liquid formulation is ammonia-free. In some embodiments, the first liquid formulation includes ammonia and monoethanolamine. In some embodiments, the first liquid formulation includes resorcinol. In some embodiments, the first liquid formulation is free of resorcinol and resorcinol derivatives.

[0036] In some embodiments, the formula delivery system includes a second formulation source storing a second liquid formulation. In some embodiments, the second liquid formulation is a developer. In some embodiments, the second liquid formulation comprises at least hydrogen peroxide. In some embodiments, the second liquid formulation is a cream or a liquid.

[0037] In some embodiments, when the first liquid formulation and the second liquid formulation are mixed, the second liquid formulation is activated. In some embodiments, the mixed formulation has a viscosity of at least 2.0 Pa-s. In some embodiments, the viscosity of the mixed formulation ranges from 2.0 Pa-s to 4.0 Pa-s.

[0038] The outlet area of ​​the reusable handle 106 includes a plurality of elongated nozzles 116 extending from a collector housing 108 coupled to or formed on the reusable handle 106. The elongated nozzles 116 are configured to discharge the coloring formulation through a plurality of outlet openings 118 in the tip of the nozzle 116 when using the hair coloring device 100. In some embodiments, the nozzles 116 are arranged in one or more rows along the length of the head of the reusable handle 106, generally in a direction along the length of the hair coloring device 100, as shown in the Figures. In other embodiments, the nozzles 116 are appropriately positioned at an angle to the length of the hair coloring device 100.

[0039] In some embodiments, the nozzles 116 have a length of between approximately 0.5 cm and approximately 4.0 cm from the manifold housing 108 to the tip of the nozzles 116 at the outlet openings 118. In other embodiments In this embodiment, the nozzles 116 have a length of approximately 1.4 cm and approximately 1.8 cm from the collector housing 108 to the end of the nozzles 116 at the outlet openings 118. In other embodiments, the nozzles 116 have a length of approximately 1.6 cm from the collector housing 108 to the end of the nozzles 116 at the outlet openings 118. In other embodiments, any nozzle length is used appropriately.

[0040] In the illustrated embodiment, a plurality of spacing projections 120 extend outward substantially in the direction of the nozzles 116 from the manifold housing 108 in one or more rows. In this respect, substantially in the direction of the nozzles 116 is understood to refer to an angle of approximately 25 degrees maximum from the direction along the length of the nozzles 116. In the depicted embodiment, the first and second rows of spacing projections 120 are positioned along each side of a single row of elongated nozzles 116. In some embodiments, the spacing projections 120 may be arranged at an angle to the plurality of nozzles 116. (For example, see US Patent Application Publication No. 15 / 339,551.)

[0041] In some embodiments, a spacing projection of the spacing projections 120 has a length (measured between the manifold housing 108 and one end of the spacing projections 120) such that the ends of the spacing projections 120 and the outlet openings 118 of the nozzles 116 are substantially coplanar. In other embodiments, the spacing projections 120 have a length (from the manifold housing 108 to the end of the spacing projection 120) such that the spacing projections 120 are longer than a length of the nozzles 116 (measured between the manifold housing 108 and one end of the nozzles 116).In this regard, during use, the spacer protrusions 120 would come into contact with an application surface, such as a localized area of ​​the scalp, and would space the outlet opening 118 of the nozzles 116 from the application surface to provide a discharge space for the coloring formulation through the outlet opening 118. In embodiments in which the spacer protrusions 120 are longer than the plurality of nozzles 116, the spacer protrusions 120 are approximately 0.1 mm to 5.0 mm longer than the length of each of the plurality of nozzles 116. In other embodiments, the spacer protrusions 120 are approximately 0.5 mm to 1.5 mm longer than the length of each of the plurality of nozzles 116. In other embodiments, the spacer protrusions 120 are approximately 1.0 mm is the length of each of the plurality of 116 nozzles.

[0042] As can be seen more clearly in [Fig. IB], a hair coloring adapter 200 is shown attaching to the reusable handle of the consumable assembly 106 substantially on the nozzles 116 and the spacing projections 120. As this As described below, the hair coloring adapter 200 includes a bristle adapter 202 and an adapter cap 204. When the hair coloring adapter 200 is coupled to the reusable handle 106, the plurality of nozzles 116 interface with the formulation orifices 224 (shown in [Fig. 2B]) within an adapter base 206 on the hair coloring adapter 200. In some embodiments, the hair coloring adapter 200 is coupled directly to the reusable handle 106. In other embodiments, the hair coloring adapter 200 is coupled to the plurality of spacer protrusions 120. In other embodiments, the hair coloring adapter 200 is coupled to the plurality of spacer protrusions 120 and to the reusable handle 106.In some embodiments, the hair coloring adapter 200 is one of several hair coloring adapters 200 that are configured to offer customization to the hair coloring device 100, as described in more detail below with respect to [Fig.2A] - [Fig.5].

[0043] Turning to [Fig. 2A] and [Fig. 2B], an embodiment of a hair coloring adapter 200 is shown. [Fig. 2A] is a side perspective view of a hair coloring adapter 200 for applying hair dye to alternating strands of a subject's hair. [Fig. 2B] is a top view of the hair coloring adapter of [Fig. 2A].

[0044] In one embodiment, the hair coloring adapter 200 is configured to clip onto a segment of the subject's hair, separating the hair segment into target and non-target strands. In this way, hair coloring can be performed in an alternating pattern to achieve a highlighting effect. An advantage of such an arrangement is that a user can customize the areas of the subject's hair that are intended to receive the hair coloring treatment.

[0045] In the illustrated embodiment, the hair coloring adapter 200 is shown as including a bristle adapter 202 and an adapter cap 204. The bristle adapter 202 is shown as including an adapter base 206, a plurality of support structures, such as support uprights 212, a plurality of formulation application zones 214, and a plurality of non-application zones 226. In some embodiments, the support structures may be a continuous support segment or wall, or similar. The adapter base 206 has a first side of the adapter base 208 and a second side of the adapter base 210. In some embodiments, the first side of the adapter base 208 is configured to couple to a hair coloring device, such as the hair coloring device 100 shown in [Fig. 1A].In some embodiments, the reusable handle 106 of the hair coloring device 100 includes magnetic attachment points that can be coupled to . Matching magnets are located in the adapter base 206. In some embodiments, the reusable handle 106 and the adapter base 206 include a conjugate pair of snap-on fasteners, such as snap-on fasteners with a quick-release tab. In some embodiments, the formulation orifices 224 include an inner diameter configured to couple tightly with the plurality of nozzles 116 on the hair coloring device 100, thus detachably coupling the adapter base 206 to the hair coloring device 100. In some embodiments, the adapter base 206 is configured to slide onto the hair coloring device. However, it should be understood that any suitable coupling mechanism can be used and falls within the scope of this disclosure.

[0046] When the hair coloring adapter 200 is coupled to the hair coloring device, such as the hair coloring device 100, the nozzles 116 are fluidly connected to the formulation orifices 224, thus allowing the formulation to flow from the hair coloring device 100 and through the hair coloring adapter 200 onto the hair of a subject. In some embodiments, the formulation orifices 224 couple directly to the nozzles 116. In other embodiments, the formulation orifices 224 couple to the nozzles 116 via a length of flexible tubing.

[0047] In the illustrated embodiment, the support uprights 212 of the bristle adapter 202 protrude from the second side of the adapter base 210. The support uprights 212 include an upper portion configured to couple with the adapter cap 204. In this way, the bristle adapter 202 and the adapter cap 204 are configured to detachably couple to each other when the bristle adapter 202 is placed on a section of the subject's hair, thereby clipping the hair segment into the hair coloring adapter. When the hair coloring adapter is clipped onto the section of the subject's hair, the hair is further divided between the plurality of formulation application zones and the plurality of non-application zones, thus allowing the formulation to be applied to alternating sections of the subject's hair.In some embodiments, the hair adapter 202 and the adapter cap 204 clip together, such as by a magnetic interface system. However, any suitable coupling method may be used and falls within the scope of this disclosure, such as flexible snap-on tabs, sliding locking tabs, clamping elements, and the like. The adapter cap 204 is configured to detachably couple to the hair adapter 202 when the hair adapter 202 is placed on a portion of the subject's hair, thereby clipping the hair segment into the hair coloring adapter 200.

[0048] In some embodiments, the support uprights 212 include a defined height extending from the base of the support upright 212 on the second side of the adapter base 210 to the opposite end of the support upright 212. The height of the support uprights 212 can be customized, thus allowing the hair coloring adapter 200 to accept a larger or smaller selection of hair strands from the subject. The advantage of accepting a larger selection of hair strands is that it allows the hair coloring adapter 200 to apply a hair coloring treatment to an entire head of hair more quickly. The advantage of accepting a smaller selection of hair strands is increased layering and customization of the strand application process.In some embodiments, the height of the support uprights 212 can be 0.5 cm, 1.0 cm, 1.5 cm, 2.0 cm, 2.5 cm, 3.0 cm, 3.5 cm, 4.0 cm, 4.5 cm or 5.0 cm.

[0049] In embodiments, the adapter cap 204 couples to the support uprights 212, thereby substantially enclosing a region between the formulation orifices 224 and the adapter cap 204. In the illustrated embodiment, the adapter cap 204 is shown as including two end portions which rest on the top portion of the support uprights 212 and are attached to the support uprights 212, for example by clipping them into place, by a magnetic fastening system, or similar.

[0050] In the illustrated embodiment, a plurality of crossbars connect the two end portions of the adapter cap 204, thus creating a cage-like structure. Such a structure has the advantage of improving visibility beneath the adapter cap 204 so that the user of the hair coloring adapter 200 can visually identify whether the hair strands are segmented into the different formulation application zones 214 and non-application zones 226. However, it should be understood that the adapter cap 204 can take the form of any structure, such as that described in more detail with reference to [Fig. 5] below.

[0051] In some embodiments, the adapter cap 204 is permanently coupled to a first set of support structures, such as support uprights 212, on a first side of the hair coloring adapter 200 and detachably coupled to a second set of support structures, such as support uprights 212, on a second side of the hair coloring adapter 200. An advantage of such a configuration is that the adapter cap 204 and the hair adapter 202 remain connected between uses, thus preventing the user from losing either component.

[0052] With reference to [Fig. 2B] - [Fig. 4B], the application area of ​​formulation 214 will now be discussed. The bristle adapter 202 is configured to include a plurality of formulation application zones 214. In the illustrated embodiment of [Fig.2B], there are five formulation application zones 214. However, it should be understood that the bristle adapter 202 may include two formulation application zones 214, three formulation application zones 214, four formulation application zones 214, five formulation application zones 214, six formulation application zones 214, seven formulation application zones 214 or eight or more formulation application zones 214.

[0053] An individual formulation application zone 214 may include one or more comb segments 216, one or more bristle brush heads 220, and one or more formulation orifices 224. For example, the formulation application zone 214 may include a first comb segment 216 and a second comb segment 216 arranged on either side of the bristle brush heads 220 and the formulation orifice 224, thus substantially enclosing the bristle brush heads 220 and the formulation orifice 224. An individual comb segment 216 has one or more comb teeth 218. As can be seen more clearly in [Fig. 3], the formulation orifice 224 defines a bore through the adapter base 206, placing the first side of the adapter base 208 in fluidic communication with the second side of the adapter base 210.The formulation orifice 224 can be coupled to a formulation source such as the nozzle 116 of the hair coloring device 100.

[0054] Referring back to [Fig. 2B] - [Fig. 4B], in some embodiments, a formulation application area 214 includes two comb segments 216. In the illustrated embodiment, the comb segment 216 is an arrangement of four comb teeth 218 substantially in a row from one front side to one rear side of the second side of the adapter base 210. Spacing between adjacent comb teeth 218 can offer several advantages, including improved ease of cleaning of the hair coloring adapter 200 between uses, minimizing material costs for manufacturing, and improving airflow during the application of the formulation to a subject's hair. However, it should be understood that the comb segment 216 can also comprise a single continuous piece of material.

[0055] The comb teeth 218 protrude from the adapter base 206. In some embodiments, the comb teeth 218 protrude from the adapter base 206 and are substantially perpendicular to the adapter base 206. In some embodiments, the comb tooth 218 protrudes from the adapter base 206 and forms an angle with respect to the adapter base 206, such as an angle of 85°, an angle of 80°, an angle of 75°, an angle of 70°, an angle of 65°, or an angle of 60°. A perpendicular orientation of the comb teeth 218 with respect to the adapter base 206 offers several advantages, including consistency in the fraction of hair captured and maintained within any of the formulation application zones 214. However, other angles can advantageously hold and retain hair segments within the formulation application zone 214 more securely during application. Thus, the angle of the comb teeth 218 can offer options for customizing the hair color adapter 200.

[0056] In embodiments, a comb tooth 218 comprises a defined height from the base of the comb tooth 218 on the second side of the adapter base 210 to the opposite end of the comb tooth 218. The height of the comb tooth 218 can be customized to hold a larger or smaller hair sample from the subject. The advantage of accepting a larger selection of hair strands is that it allows the hair coloring adapter 200 to apply a hair coloring treatment to an entire head of hair more quickly. The advantage of accepting a smaller selection of hair strands is increased layering and customization of the strand application treatment. In some embodiments, the height of the comb tooth 218 can be 0.5 cm, 1.0 cm, 1.5 cm, 2.0 cm, 2.5 cm, 3.0 cm, 3.5 cm, 4.0 cm, 4.5 cm or 5.0 cm.In some embodiments, the height of the comb tooth 218 is substantially the same as the height of the support post 212, so that a tip of the comb tooth 218 comes into contact with the adapter cap 204 when the adapter cap 204 is clipped onto the support post 212. In some embodiments, the comb teeth 218 include additional coupling means, such as magnets, to provide additional coupling between the adapter cap 204 and the bristle adapter 202. In some embodiments, the height of the comb tooth 218 is less than that of the support post 212.

[0057] In some embodiments, a comb tooth 218 comprises a length with a first side and a second side. The first side is coupled to the adapter base 206 and has a width that is greater than the width of the second side of the comb tooth 218. In some embodiments, the width of the comb tooth 218 on the first side is substantially the same as the width of the comb tooth 218 on the second side. In some embodiments, the comb teeth 218 have an average width of 5 mm, 4 mm, 3 mm, 2 mm, or 1 mm. In some embodiments, the comb teeth 218 have a material composition that is substantially the same as the material composition of the adapter base 206.In some embodiments, the comb teeth 218 comprise a polymeric material, such as acrylonitrile butadiene styrene (ABS) plastic, high-density polyethylene (HDPE) plastic, a rubberized material, and the like.

[0058] The non-application zone 226 is defined as the space between adjacent formulation application zones 214. For example, a non-application zone 226 can be defined as the space between the second comb segment 216 of a first application zone of formulation 214 and the first comb segment 216 of a second application zone of formulation 214. In some embodiments, an application zone of formulation 214 defines an application zone width, and a non-application zone 226 defines a non-application zone width. In some embodiments, the application zone width is greater than the non-application zone width. In some embodiments, the application zone width is substantially the same as the non-application zone width. In some embodiments, the application zone width is smaller than the non-application zone width.

[0059] The relative sizes of the application zone width and the non-application zone width can advantageously be selected to expose a larger or smaller portion of a subject's hair to a coloring formulation. In some embodiments, the size of the width of a plurality of non-application zones 226 can vary, such that some non-application zones 226 have a greater width than other non-application zones 226. In some embodiments, the size of the width of a plurality of formulation application zones 214 can vary, such that some formulation application zones 214 have a greater width than other formulation application zones 214. Such an arrangement can allow the use of the hair coloring adapter 200 to obtain a textured or layered coloring pattern in the subject's hair.

[0060] Returning to the formulation application areas 214, and as better shown in [Fig.3] - [Fig.4B], an individual bristle brush head 220 includes a plurality of bristles 222. In embodiments, the formulation application area 214 includes two or more bristle brush heads 220. A bristle brush head 220 protrudes from the adapter base 206. When a formulation application area 214 includes two comb segments 216, the bristle brush head 220 protrudes from the adapter base 206 and is positioned between a pair of the comb segments 216. The bristle brush head 220 is configured to surround the formulation orifice 224. For example, when there are two bristle brush heads 220, one bristle brush head 220 is positioned along an outer edge of the adapter base 206 with the formulation orifice 224 positioned substantially in the middle.In some embodiments, a simple bristle brush head 220 is an annular bristle brush head 220 and is positioned to substantially surround the formulation orifice 224. In some embodiments, a simple bristle brush head 220 forms a rectangular toroidal section.

[0061] In some embodiments, a hair 222 of the plurality of hairs 222 defines a height and a width. The hair 222 protrudes from the adapter base 206. In some embodiments, the height of the hair 222 and the height of the comb tooth 218 are substantially identical. In some embodiments, the height of the hair 222 is greater than the height of the comb tooth 218. In some embodiments, the height of the hair 222 is less than the height of the comb tooth 218. In some embodiments, the width of the hair 222 is less than the width of the comb tooth 218. In some embodiments, the hair 222 has an average width of 500 pm, 450 pm, 400 pm, 350 pm, 300 pm, 250 pm, 200 pm, 150 pm, 100 pm, 90 pm, 80 pm, 70 pm, 60 pm or 50 pm.

[0062] In some embodiments, the bristle 222 comprises a polymeric material, such as ABS plastic, HDPE plastic, a rubberized material, and the like. In other embodiments, the bristle 222 is an animal hair, such as horsehair, boar bristle, and the like. The relatively small average width of the bristles 222 compared to the comb teeth 218 offers advantages in the application of the hair formulation. A thinner bristle 222 is more flexible and allows a greater number of bristles 222 within a given area of ​​the adapter base 206. This increases the total contact area between the bristles 222 and the hair strands of a subject, thus improving the quality of the formulation transfer. Conversely, a relatively thick average width of the comb teeth 218 provides a rigid barrier, thus maintaining the desired segmentation of the subject's hair into various hair strand segments.

[0063] In some embodiments, the bristle brush head 220 is configured to wipe the formulation onto a subject's hair. For example, when the formulation is dispensed from the formulation orifice 224, it adheres loosely to the bristle brush head 220. When the user pulls the hair coloring adapter 200 along the strand of hair to which it is clipped, the bristles 222 of the bristle brush head 220 intertwine with the individual hairs of the subject, thus transferring the formulation onto the subject's hair. Only a portion of the total formulation exuded toward the bristle brush head 220 is transferred at any given time, thus allowing for a uniform transfer of the formulation onto the subject's hair.

[0064] In some embodiments, the bristle brush head 220 is configured to remove the formulation from a subject's hair. For example, after a first bristle brush head 220 has wiped the formulation from the subject's hair, a second bristle brush head 220 intertwines with individual hairs of the subject. The second bristle brush head 220 contains less formulation, and thus extracts the excess formulation from the subject's hair when the user pulls the adapter. The hair coloring applicator is 200g long and attached to the hair strand. This allows for consistent formula application while minimizing product waste and mess during post-application cleanup. This arrangement also improves the consistency of results, for example, when the amount of hair coloring solution in a particular area affects the coloring effect.

[0065] In some embodiments, an individual formulation 214 application zone is substantially identical to the other formulation 214 application zones. In some embodiments, one or more individual formulation 214 application zones include a structure different from the other formulation 214 application zones as discussed in more detail above with respect to the various embodiments of the formulation 214 application zone. In various embodiments, the various features described herein are mixed and matched to obtain a desired coloring effect.For example, a formulation application area 214 substantially in the middle of the hair coloring adapter 200 can be configured to apply a greater quantity of formulation than a formulation application area 214 near either end of the hair coloring adapter 200, thereby improving the blending of coloring effect between a first use of the hair coloring adapter 200 and a second use of the hair coloring adapter 200 on a different segment of the subject's hair.

[0066] As can be seen more clearly in [Fig.2B], in some embodiments, the formulation application zones 214 and the non-application zones 226 are arranged in an alternating pattern whereby no formulation application zone 214 is directly adjacent to a second formulation application zone 214. However, it should be understood that other arrangements are possible, such as when two formulation application zones 214 are separated by several comb segments 216, thus adding further separation between adjacent formulation application zones 214.In embodiments, multiple application zones of formulation 214 may be directly adjacent to each other, for example, where a first application zone of formulation 214 shares a common comb segment 216 with a second application zone of formulation 214, resulting in two or more application zones of formulation 214 without intermediate non-application zones 226.

[0067] A second embodiment of the hair coloring adapter 500 will now be described with reference to [Fig. 5]. The hair coloring adapter 500 is substantially identical to the hair coloring adapter 200, except that the adapter cap 505 of the hair coloring adapter 500 differs from the 204 adapter cap of the 200 hair coloring adapter. Thus, parts of the 500 hair coloring adapter will be labeled with the same part numbers as the 200 hair coloring adapter, except in the 500 series. Furthermore, only the 505 adapter cap and how it affects the function of the 500 hair coloring adapter will be described in detail.

[0068] The hair coloring adapter 500 is shown to include the adapter cap 505. The adapter cap 505 comprises a single continuous upper portion. In some embodiments, the adapter cap 505 couples to the support uprights 212, thereby substantially enclosing a region between the formulation orifices (not shown) and the adapter cap 505. The adapter cap 505 is configured to make contact with a plurality of support structures (not shown), such as the support upright 212, described in more detail above with respect to [Fig. 2A]–[Fig. 4B], for example, by clipping them into place, by a magnetic fastening system, or similar. Advantageously, by comprising a single detachable piece, the adapter cap 505 can offer improved cleaning between uses of the hair coloring adapter 500, and improved retention of the hair strands and formulation..

[0069] In some embodiments, the adapter cap 505 is permanently coupled to support structures on one side of the hair coloring adapter 500 and detachably coupled to support structures on a second side of the hair coloring adapter 500. An advantage of such a configuration is that the adapter cap 505 and the hair adapter 502 remain connected between uses, thus preventing the user from losing either component.

[0070] In one aspect, the present disclosure proposes a method for coloring alternating strands of a subject's hair. With reference to [Fig. 6], routine 600 illustrates a hair dyeing method according to one embodiment of the present disclosure. In block 602, a hair coloring adapter, such as hair coloring adapter 200, described in more detail here with reference to [Fig. 2A]–[Fig. 4B], is clipped onto a first segment of the subject's hair.

[0071] At block 604, the hair coloring adapter is coupled to a hair coloring device, such as the hair coloring device 100, described in more detail here with reference to [Fig. 1A] - [Fig. 1B]. At block 606, the hair coloring device is activated, for example by pressing the control button 104 to initiate a flow of formulation, such as through the nozzles 116. At block 608, the user pulls the hair coloring adapter along the segment clipped from the subject's hair, thus depositing the hair formulation onto the clipped segment of the subject's hair by brushing.

[0072] In some embodiments, the hair coloring adapter includes a bristle adapter and an adapter cap detachably coupled to the bristle adapter. In some embodiments, the bristle adapter includes an adapter base, a plurality of support structures projecting from the adapter base and configured to couple with the adapter cap, a plurality of formulation application zones disposed on the second side of the adapter base, a plurality of non-application zones disposed on the second side of the adapter base, and a plurality of formulation orifices defining a fluid path from the first side of the adapter base to the second side of the adapter base.

[0073] In optional block 610, the user unclips the hair coloring adapter from the first hair segment and then clips the hair coloring adapter onto a second hair segment. After completion of optional block 610, routine 600 can be repeated, starting with block 604.
