Description

Technical Field

[0001] The present invention relates to a hair styling method.

Background Art

[0002] In order to achieve a desired hair styling, it is generally practiced to wash the hair or wet it by applying water thereto, and then dry the hair while applying heat from a dryer. However, since the hair has various shapes such as flyaways, fuzz, undulations, and twists, it may be difficult to straighten the hair or suppress the spread of the hair.

[0003] Conventionally, for example, a fiber bundle for hair obtained by blending 10 to 90% by weight of regenerated collagen fiber and 90 to 10% by weight of human hair is passed through a comb while being immersed in water for 5 minutes or more, taken out of the water to remove the moisture on the fiber surface, then stretched and arranged with a comb, and naturally dried, thereby improving the accumulation of frizz, which is a drawback of a hair accessory product using human hair as a fiber for the hair accessory product, and imparting a permanent wave performance, which is a drawback of a hair accessory product using regenerated collagen fiber as a fiber for the hair accessory product. It has been reported (Patent Document 1).

Summary of the Invention

Problems to be Solved by the Invention

[0005] However, Patent Document 1 merely discloses a technology that can simultaneously overcome the problem of frizz accumulation, which is characteristic of human hair products, and the problem of the lack of permanent wave performance, which is characteristic of headwear products derived from regenerated collagen fibers, by blending human hair and regenerated collagen fibers in a certain ratio. It does not intend to straighten existing natural hair or suppress hair spreading. The present invention relates to a hair styling method that can straighten hair or suppress hair from becoming frizzy. [Means for solving the problem]

[0006] In view of the above-mentioned problems, the inventors of the present invention have found that by attaching a head accessory product containing fibers for head accessories to the hair, wetting the hair, and then drying the hair and the fibers for the head accessory product while simultaneously applying tension in the length direction, the hair can be straightened or its spreading can be suppressed.

(I) The process of attaching a head accessory product containing fibers for head accessories to the hair. (II) Process of wetting the hair (III) A process of drying hair and fibers for headwear products while simultaneously applying tension in the length direction. [2] The hair styling method according to [1], wherein the elastic modulus of the fibers for headwear products is 0.1 GPa or more and 10 GPa or less in water. [3] The hair styling method according to [1] or [2] above, wherein the fibers for the head ornament product include regenerated protein fibers. [4] A hair styling method according to any one of [1] to [3] above, wherein step (II) is washing the hair. [5] The hair styling method according to any one of [1] to [4] above, wherein in step (III), hot air at 45°C or higher and 90°C or lower is applied to dry the hair. [6] The hair styling method according to any one of [1] to [5] above, wherein tension is applied using fingers or a hair styling tool in step (III). [7] The hair styling method described in [6] above, wherein the hair styling tool is a comb or a brush. [8] Headwear products including fibers for headwear products, and hair styling headwear kits including hair styling tools. [Effects of the Invention]

[0008] According to the present invention, it is possible to provide a hair styling method that can straighten hair or suppress hair from spreading out. [Modes for carrying out the invention]

[0009] First, let's explain the terminology used in this specification. (headdress products) In this specification, "head ornaments" means decorative items used to adorn a person's head, and may include, for example, hair wigs, hairpieces, weaving, hair extensions, braided hair, hair accessories, and doll hair. Methods of attaching hair extensions include, for example, adhesives, clips, weaving, braiding, glue, and clip-ins. Hair wigs may also be partial wigs. (Fiber for headdress products) In this specification, "fibers for headwear products" means fibers used in headwear products. (hair) In this specification, "hair" refers to the hair that is the subject of the hair styling according to the present invention, and mostly refers to naturally growing hair, and is distinguished from "human hair" used for headwear products. "Human hair" as used herein refers to hair fibers used in headwear products.

[0010] [Hair styling method] The hair styling method of the present invention comprises the following steps (I), (II), and (III), characterized in that step (III) is performed after steps (I) and (II). (I) The process of attaching a head accessory product containing fibers for head accessories to the hair. (II) Process of wetting the hair (III) A process of drying hair and fibers for headwear products while simultaneously applying tension in the length direction.

[0011] In the hair styling method of the present invention, the order of steps (I) and (II) is not particularly limited, as long as step (III) is performed last among steps (I) to (III). Step (I) may be performed before or after step (II). That is, the hair styling method of the present invention can be performed in either of the following (a) or (b). Of these, (a) is preferred in that it is easier to enjoy the desired effect. (a) The process is carried out in the order of (I), (II), and (III). (b) Process (II), process (I), process (III) in that order.

[0012] The following describes each step. <Process (I)> Step (I) is the step of attaching a head accessory product, which includes fibers for head accessories, to the hair. For headwear products, either naturally derived fibers or synthetic fibers may be used, but naturally derived fibers are preferred. Naturally derived fibers refer to fibers collected from natural animals and plants, or fibers artificially manufactured using polymers or oligomers such as proteins and polysaccharides derived from keratin, collagen, casein, soybeans, peanuts, corn, silk waste, silk protein (e.g., silk fibroin), etc. Of these, animal hair, human hair, or fibers artificially manufactured using polymers or oligomers such as proteins and polysaccharides derived from keratin, collagen, casein, soybeans, peanuts, corn, silk waste, silk protein (e.g., silk fibroin), etc. are preferred, regenerated protein fibers made from proteins derived from keratin, collagen, casein, soy protein, peanut protein, corn protein, silk protein (e.g., silk fibroin), etc. are more preferred, regenerated protein fibers such as regenerated collagen fibers made from collagen, and regenerated silk fibers made from silk fibroin are even more preferred, and regenerated collagen fibers are even more preferred.

[0013] The regenerated collagen fibers can be manufactured by known techniques. The composition of the regenerated collagen fibers does not necessarily have to be 100% collagen, and may contain natural polymers, synthetic polymers, additives, etc. for quality improvement. Furthermore, the regenerated collagen fibers may be post-processed or post-treated. As the form of the regenerated collagen fibers, filaments are preferred. The filaments are generally taken out from those in a bobbin-wound state or a box-packed state. Also, the filaments coming out of the drying process in the manufacturing process of the regenerated collagen fibers can be directly used.

[0014] Examples of the synthetic fibers include fibers containing a synthetic resin as a main component. From the viewpoint of the ease of manufacturing synthetic fibers and the viewpoint of obtaining a texture similar to human hair, the synthetic resin is preferably a thermoplastic resin, more preferably one or more selected from the group consisting of polyester resins, polyamide resins, polyimide resins, polyamideimide resins, vinyl chloride resins, polycarbonate resins, polyphenylene sulfide resins, and modacrylic resins (copolymers of acrylonitrile and vinyl chloride). Here, the "main component" means a component having a content in the synthetic fiber of preferably 50% by mass or more, more preferably 60% by mass or more, still more preferably 70% by mass or more, even more preferably 80% by mass or more, even more preferably 90% by mass or more, and may be 100% by mass. In addition to the above synthetic resin, the synthetic fibers can contain various components such as flame retardants, flame retardant aids, light or heat stabilizers, fluorescent agents, antioxidants, antistatic agents, and ultraviolet absorbers within a range that does not inhibit the effects of the present invention.

[0015] The fiber for the headgear product preferably has a modulus of elasticity in water of 0.1 GPa or more, more preferably 0.2 GPa or more, still more preferably 0.3 GPa or more, and preferably 10 GPa or less, more preferably 6 GPa or less, still more preferably 3 GPa or less, and even more preferably 1 GPa or less, from the viewpoint of straightening the hair or suppressing the spread of the hair. That is, such a modulus of elasticity in water is preferably 0.1 GPa or more and 10 GPa or less, more preferably 0.2 GPa or more and 6 GPa or less, still more preferably 0.3 GPa or more and 3 GPa or less, and even more preferably 0.3 GPa or more and 1 GPa or less.

[0016] In this step, the headgear product is worn on the hair. Here, in this specification, "wearing" means laying the fiber for the headgear product on the hair portion to be arranged and fixing the headgear product to the hair, and it may be the whole hair or a part thereof.

[0017] The wearing method is not particularly limited as long as the headgear product can be fixed to the hair. For example, methods such as tying the fiber for the headgear product to the hair, knitting the fiber for the headgear product into the hair, and using a fixing member can be mentioned. Also, as long as a certain fixing force can be ensured, the headgear product may be adhered to the hair with (double-sided) tape, seal, adhesive, etc. Note that the fixing method may be a removable fixing method.

[0018] The wearing method using a solid member is not particularly limited as long as it is a method generally adopted in the technical field. For example, a method of locking a sheet-shaped solid member having a plurality of openings at the end to the base of the fiber for the headgear product and inserting and binding the hair through the openings (for example, Japanese Patent Laid-Open No. 11-131315), a method of locking a thread to the base of the fiber for the headgear product and tying and binding the hair to the thread, and a method of locking a jig to the base of the fiber for the headgear product and sandwiching and binding the hair with this jig can be mentioned. The jig is not particularly limited as long as the headgear product can be removably fixed, and examples include a clip that can be opened and closed, a ring, a surface fastener, etc.

[0019] The ratio of hair to hair accessories is preferably 1% by mass or 100% by mass or less, as a mass ratio of hair accessories to the total amount of hair accessories [(hair accessories / (hair accessories + hair)], from the viewpoint of straightening the hair or suppressing hair spreading. This mass ratio [hair accessories / (hair accessories + hair)] is preferably 1% by mass or more and 100% by mass or less.

[0020] In this process, the ratio of hair to hair fibers can be appropriately set according to the type of hair accessory product, from the perspective of straightening the hair or more effectively suppressing hair frizz. An example is described below. (i) Partial wig When a partial wig is 5 cm or wider, for example, from the viewpoint of suppressing the spread of the hair on the entire head, the following configuration can be used. That is, the mass ratio of the hair product fibers in the partial wig to the total amount of hair on the entire head [hair product fibers / (hair product fibers + hair)] is preferably 5.0% by mass or more, more preferably 10% by mass or more, even more preferably 20% by mass or more, and preferably 70% by mass or less, more preferably 50% by mass or less, and even more preferably 30% by mass or less. Such a mass ratio [hair product fibers / (hair product fibers + hair)] is preferably 5.0% by mass or more and 70% by mass or less, more preferably 10% by mass or more and 50% by mass or less, and even more preferably 20% by mass or more and 30% by mass or less. (ii) Hair extensions When the width of the hair extension is less than 5 cm, for example, from the viewpoint of straightening the hair at the attachment site or suppressing the spreading of the hair at the attachment site, the following configuration can be used. That is, the mass ratio of the fibers for head accessories to the total amount of hair in the hair extension and the fibers for head accessories in the hair extension, from both ends in the width direction of the hair extension to a region of 50% width of the hair extension, is preferably 1% by mass or more, more preferably 5.0% by mass or more, even more preferably 10% by mass or more, and preferably 100% by mass or less, more preferably 70% by mass or less, and even more preferably 50% by mass or less. Such a mass ratio [fibers for head accessories / (fibers for head accessories + hair)] is preferably 1% by mass or more and 100% by mass or less, more preferably 5.0% by mass or more and 70% by mass or less, and even more preferably 10% by mass or more and 50% by mass or less. Furthermore, "hair within a region 50% of the hair extension width from both ends in the width direction of the hair extension" refers to hair located in a region that extends 50% of the hair extension width horizontally from the ends in the width direction of the hair extension, using the horizontal width of the hair to which the hair extension should be attached as an indicator. (iii) Method of attaching fibers for headwear products to hair When tying the fibers for the head accessory product to the root of each individual hair, the mass ratio of the fibers for the head accessory product to the total amount of hair in the area including the attached hair and the fibers for the head accessory product [fibers for the head accessory product / (fibers for the head accessory product + hair)] is preferably 1% by mass or more, more preferably 5.0% by mass or more, even more preferably 10% by mass or more, and preferably 100% by mass or less, more preferably 70% by mass or less, and even more preferably 50% by mass or less. Such a mass ratio [fibers for the head accessory product / (fibers for the head accessory product + hair)] is preferably 1% by mass or more and 100% by mass or less, more preferably 5.0% by mass or more and 70% by mass or less, and even more preferably 10% by mass or more and 50% by mass or less. In this context, when the fibers for the head accessory product are tied to the root of each individual hair, the "area including the attached hair" refers to the area inside the polygon with the largest area among the polygons whose vertices are the roots of the hair to which the fibers for the head accessory product are tied.

[0021] <Process (II)> Step (II) is a step in which the hair is made moist. This causes the hair to contain a certain amount of moisture, which lowers the elastic modulus of the hair and makes it easier to mix the hair with the fibers for the head accessory product. When the head accessory product is to be attached to the entire head of hair, the entire head of hair should be made moist, and when the head accessory product is to be attached to only a part of the head of hair, only that part should be made moist. Here, in this specification, "moist" means a state in which moisture is contained in the hair.

[0022] There are no particular limitations on the method of moistening the hair, as long as the hair is in a state where it contains moisture. For example, this could involve washing the hair or wetting it with water using a spray or the like. Among these, washing the hair is preferred because it easily moistens it. You may use shampoo to wash your hair, and you may do so once or more times. There are no particular restrictions on the type of shampoo you can use; commercially available products are acceptable.

[0023] As for the wet state, the water content in the hair is not particularly limited, but from the viewpoint of facilitating mixing of hair with fibers for headwear products, straightening the hair, or suppressing hair spreading, when the mass of hair after 24 hours of conditioning at 20°C and 65% relative humidity is set to 1.0, the mass ratio of water to hair (water / hair) is preferably 0.005 or more, more preferably 0.10 or more, even more preferably 0.2 or more, and preferably 1.0 or less, with a further preference of 0.5 or less. That is, such a mass ratio (water / hair) is preferably 0.005 or more and 1.0 or less, more preferably 0.10 or more and 0.5 or less, and even more preferably 0.2 or more and 0.5 or less. Furthermore, from the viewpoint of facilitating mixing of hair and headwear fibers, it is preferable that the headwear fibers are also in a moist state. In this case, the method for moistening the headwear fibers can be the same as that used for hair, and the preferred range for the mass ratio of water to headwear fibers in the moist state (water / headwear fibers) is the same as the mass ratio of water to hair, but it does not necessarily have to be the same mass ratio as that of the hair being worn.

[0024] When styling hair in the order described in (b) above, for example, in step (II), at least one of the hair and the fibers for the head accessory product may be made wet first, and then the head accessory product may be attached to the hair and mixed together to achieve the mass ratio of water to hair (water / hair) described above. For example, to moisten hair, one can either wash their hair or wet it with water using a spray. On the other hand, to moisten fibers for headwear products, one can either bring the fibers into contact with running water, immerse them in water, or wet them with water using a spray.

[0025] After wetting the fibers for hair and headwear products, towel-drying may be performed to remove excess moisture from the fibers. However, if the fibers contain excessive moisture from washing or other processes, towel-drying is preferably performed afterward.

[0026] <Process (III)> This process involves drying hair and hair accessory fibers simultaneously while applying tension in the length direction. By drying the hair and hair accessory fibers together while simultaneously applying tension in the length direction and stretching them, the hair is straightened along the hair accessory fibers, resulting in a straighter hair flow after drying, or preventing the hair from spreading out. In terms of length, it is preferable that the direction is from the roots to the tips of the hair, as this makes it easier to style the hair straight.

[0027] The tension applied to the fibers for hair and headwear products is preferably 0.5N or more, more preferably 1.0N or more, even more preferably 2.0N or more, and even more preferably 3.0N or more, from the viewpoint of straightening the hair or suppressing hair spreading, and from the viewpoint of preventing excessive damage to the fibers for hair and headwear products, it is preferably 10N or less, more preferably 9.5N or less, even more preferably 9.0N or less, and even more preferably 8.5N or less. That is, such tension is preferably 0.5N or more and 10N or less, more preferably 1.0N or more and 9.5N or less, even more preferably 2.0N or more and 9.0N or less, and even more preferably 3.0N or more and 8.5N or less. Furthermore, the tension can be measured according to the dynamic combing force method (Suzuki et al.; J. Soc. Cosmet. Chem. Japan. Vol. 27, No.1, P11-13, 1993). The maximum combing force when combing with a brush will be taken as the measurement value, and the average of 30 measurements will be calculated.

[0028] To apply even and widespread tension to the fibers of hair and hair accessories simultaneously, a comb or hair styling tool can be used. The hair styling tools are not particularly limited as long as they are tools for combing the hair and can stretch the hair and fibers of the hair accessories evenly and over a wide area in the longitudinal direction. Examples include combs and brushes. Among these, brushes are preferred as hair styling tools. Commercially available brushes may be used, but round brushes and paddle brushes are preferred because they can easily apply the desired tension evenly and over a wide area simultaneously to the hair and fibers of the hair accessories. Examples include the Tangle Tamer from Denman International and the Goody from Beauty By Imagination.

[0029] In this process, warm air may be applied to dry the hair. A hair dryer can be used to apply warm air, for example. The hair dryer may be one that has a detachable brush attached to the air outlet.

[0030] The temperature of the hot air is preferably 45°C or higher, more preferably 60°C or higher, from the viewpoint of obtaining sufficient styling effect by applying sufficient heat to the hair for drying. Furthermore, from the viewpoint of preventing excessive damage to the hair and hair accessories, it is preferably 90°C or lower, and more preferably 80°C or lower. Here, the temperature of the hot air shall be measured directly at the nozzle of the hair dryer.

[0031] A preferred embodiment of this process is, for example, taking an appropriate amount of hair bundle from hair and hair accessory fibers, applying warm air from a hair dryer to it, and simultaneously stretching the hair bundle from the root to the tip using a hair styling tool. The width of the aforementioned appropriate amount of hair bundle is preferably 1 cm or more, more preferably 2 cm or more, preferably 10 cm or less, more preferably 8 cm or less, and even more preferably 5 cm or less, in terms of easily applying a predetermined tension to the hair and fibers for headwear products. That is, the width of such hair bundle is preferably 1 cm or more and 10 cm or less, more preferably 2 cm or more and 8 cm or less, and even more preferably 2 cm or more and 5 cm or less. The time spent stretching the hair with styling tools while applying warm air from a hair dryer is preferably 2 seconds or more, more preferably 3 seconds or more, and even more preferably 5 seconds or more, from the viewpoint of applying sufficient heat to the hair and drying it to obtain a sufficient styling effect. From the viewpoint of preventing excessive damage, it is preferably 20 seconds or less, more preferably 18 seconds or less, and even more preferably 15 seconds or less. In other words, the stretching time is preferably 2 seconds or more and 20 seconds or less, more preferably 3 seconds or more and 18 seconds or less, and even more preferably 5 seconds or more and 15 seconds or less, per stretch. It is preferable to repeat this stretching operation until the hair bundle is dry.

[0032] [Hair styling headpiece kit] The present invention includes a hair styling headpiece kit comprising a headpiece product containing fibers for headpiece products and hair styling tools. Using such a hair styling headpiece kit makes it easier to straighten the hair or control frizz, thus making it easy to style the hair into a desired hairstyle. The hair styling headpiece kit of the present invention may contain the headpiece product and the hair styling tools individually in separate areas partitioned by dividers within a single container, or they may be individually contained in separate containers. The specific forms of headwear products and hair styling tools, including fibers for headwear products, are as described above. [Examples]

[0033] 1. Modulus of elasticity in water (GPa) The elastic modulus of the fiber under tensile stress in water was measured using the following procedure. The values ​​used were the average values ​​obtained when evaluating multiple fibers (5 fibers). A higher value indicates greater stiffness, resistance to stretching due to external forces, and superior durability. (Step 1) Five fibers were cut from the fiber bundle, and a 3 cm fiber piece was taken from each, resulting in a total of five 3 cm fiber pieces. (Step 2) Fiber samples were placed in an automatic fiber tensile testing machine (MTT690, manufactured by DIA-STRON limited). After leaving the fibers immersed in water for 30 minutes, automatic tensile testing was started to determine the elastic modulus of the fibers under water. The cross-sectional area of ​​the fibers under water, which is necessary for determining the elastic modulus, was measured separately by direct observation using an optical microscope.

[0034] 2. Tension (combing force) The combing force when combing with a brush at a constant speed (once per second) was measured using the dynamic combing force method (Suzuki et al.; J. Soc. Cosmet. Chem. Japan. Vol. 27, No.1, P11-13, 1993), and the maximum value was taken as the measurement value. The average of 30 measurements was then calculated.

[0035] 3.Materials used The materials used in this embodiment are as follows: (hair bundles) Using Caucasian curly hair (purchased from Kerling International Haarrfabrik), a hair bundle was created with a length of 30.0 cm, a base hair bundle width of 2.5 cm, and a weight of 5.0 g. (Headdress product hair bundle) Using the hair accessories fibers listed below, a hair bundle with a length of 26.0 cm, a base hair bundle width of 2.5 cm, and a weight of 1.0 g was prepared. (1) Regenerated collagen fiber: Manufactured by Kaneka Corporation (*1), with a water modulus of elasticity of 0.4 GPa *1: Kaneka Corporation's regenerated collagen fibers were purchased in the form of commercially available hair extension products, and the fibers were cut and divided into small bundles for evaluation. For this evaluation, the extension products used were those labeled as using 100% Ultima fiber, with a color count of 3 (brown), and a straight shape. (2) Human hair: Bellami Hair Co., Ltd., underwater elastic modulus 1.5 GPa (3) Synthetic fiber: Polyester (*2), water modulus of elasticity 5.4 GPa *2: LineaStoria hair extensions (number: 1150004ST) were purchased in their original form, and the fibers were cut and divided into small bundles for evaluation. For this evaluation, we used extension products that were labeled as containing polyester fiber and had a straight shape.

[0036] Examples 1-3 <Process (I)> The hair strands and the fibers for headwear products shown in Table 2 were secured at the roots using tape. <Process (II)> The hair bundles prepared in step (I) were treated with the plain shampoo shown in Table 1 (0.6g applied per 6g total hair bundle; bath ratio 1:0.1), lathered and washed for 15 seconds, and then rinsed with running water for 30 seconds. After rinsing, excess water was removed by towel drying for 45 seconds. <Process (III)> A damp section of hair was combed with a 10cm wide round brush (Goody, manufactured by Beauty By Imagination) and blow-dried with hot air at a temperature of 80°C. The brushing time (the time during which hot air was applied while straightening the hair) was 5 seconds per pass, and this was repeated 24 times (totaling 2 minutes). The tension in Example 1 was 8.1N.

[0037] Comparative Example 1 Without performing step (I), the procedure was carried out in the same manner as in Example 1, in the order of steps (II) and (III).

[0038] [Table 1]

[0039] <Evaluation of coherence> Immediately after step (III), the width [L (cm)] of the hair bundle was measured at a point 15 cm from the root to the tip. Then, using the width (L0 (cm)) at a point 15 cm from the root to the tip of the hair bundle dried with only hot air without brushing as a reference, the hair bundle width reduction rate (%) was calculated using the following formula.

[0040] Hair bundle width reduction rate (%)=(L0-L) / L0×100

[0041] Then, the hair bundle width reduction rate (%) was evaluated according to the following criteria. (Evaluation Criteria) 5: The hair bundle width reduction rate is 50% or more. 4: The hair bundle width reduction rate is 40% or more but less than 50%. 3: The hair bundle width reduction rate is 25% or more but less than 40%. 2: The hair bundle width reduction rate is 20% or more but less than 25%. 1: The hair bundle width reduction rate is less than 20%.
