Description

The present invention relates to a hair thickening method .

Hair materials for hair augmentation and cosmetic purposes have traditionally been attached to one's own hair, but this attachment process requires manual attachment of the hair materials one by one to positions as close to the roots as possible, and because the hair materials themselves are very thin, the attachment process is difficult and requires a long time to attach many strands. Therefore, a method was developed in which hair for hair augmentation is tied to one's own hair (for example, Patent Document 1).

Patent No. 3210081

However, as the natural hair grows, the knot moves toward the tip, making the knot more noticeable. To avoid this, the hair extension needs to be redone. As a result, the method of Patent Document 1 is also not an easy method.

In view of the above circumstances, the present invention aims to provide a hair growth method that can be carried out more easily.

The hair augmentation method of the present invention comprises a bonding step of bonding one artificial hair to one natural hair using an adhesive, and a temporary fixing step, which is performed before the bonding step, of temporarily fixing the one artificial hair to the one natural hair using a temporary fixing agent, wherein the one artificial hair comprises a plurality of filaments, the base ends of which are integrated with each other, and the temporary fixing step comprises a temporary fixing agent application step of applying the temporary fixing agent to at least one of the root side of the natural hair and the base end portion of the artificial hair, and a contact step, which is performed after the temporary fixing agent application step, of bringing the root side of the natural hair in an upright state into contact with the base end portion of the artificial hair, wherein the natural hair is head hair.

In the bonding step, it is preferable that the adhesive is applied so as to cover the portions of the natural hair and the artificial hair to which the temporary fixing agent has been applied. It is preferable that the method includes a raising step, which is performed before the temporary fixing step, of raising the natural hair, and in the raising step, the natural hair is raised using a hair-growth work support tool placed on the head. It is preferable that the method includes a placing step, which is performed before the raising step, of placing the hair-growth work support tool on the head , and in the placing step, the surrounding natural hair growing around the target natural hair is laid down using the hair-growth work support tool . It is preferable that the adhesive has photocuring properties, and the bonding step includes an adhesive application step of applying the adhesive to the natural hair and the artificial hair, and an adhesive hardening step of irradiating light onto the adhesive applied in the adhesive application step to harden the adhesive . The adhesive is photocurable, and the adhesion step includes an adhesive application step of applying the adhesive to the natural hair and the artificial hair, and an adhesive hardening step of applying light to the adhesive applied in the adhesive application step to harden the adhesive, and further includes a placement step, which is performed before the standing step, of placing the hair growth work support tool on the head, and the hair growth work support tool includes a surrounding hair laying member that lays down the surrounding natural hair growing around the target natural hair, and an engagement member that protrudes upward from an upper portion of the surrounding hair laying member, and the surrounding hair laying member has light blocking properties, and in the standing step, the natural hair is raised using the engagement member, and in the placement step, the surrounding natural hair growing around the target natural hair is laid down using the surrounding hair laying member. The temporary fixing agent preferably contains a component represented by the following formula 1.
Formula 1 CH ₂ =C(CN)COOR
wherein R is selected from an alkyl group, an alkoxyalkyl group, a cycloalkyl group, a haloalkyl group, an alkenyl group, an alkynyl group, an arylalkyl group, and an aryl group.

The present invention provides a hair growth method and a tool to assist in hair growth that can be performed more easily.

FIG. 4 is an enlarged view showing an outline of a hook member. 1 is a flowchart of a hair augmentation method. This is an enlarged view of the main parts of the hair augmentation method. An oblique view showing an overview of the second hair growth work support tool.

For ease of explanation, any direction in a horizontal plane will be referred to as the X direction, any direction in the horizontal plane that is perpendicular to the X direction will be referred to as the Y direction, and any direction perpendicular to the horizontal plane will be referred to as the Z direction. In addition, the part of the natural hair GM that is set on the hair root side and to which adhesive is applied will be defined as the applied part GM1, and the tip part GM2 that is located further towards the tip side than the applied part GM1. The length of the natural hair GM is set appropriately, but is preferably 10 mm or more, for example, and more preferably 30 mm or more.

As shown in Figures 1 and 2, the hair growth work support tool 2 includes a holding member 10 for laying down the surrounding natural hair growing around the target natural hair GM, an engagement member 20 that engages with the tip portion GM2 of the natural hair GM, and a hook member 30 that engages with the natural hair GM.

The holding member 10 is for placing on the head and is formed in a plate shape. The holding member 10 is formed in a rectangular shape extending in the X and Y directions. An opening 10X is formed in the holding member 10 for inserting the natural hair GM. The position of the opening 10X need only be such that the tip portion GM2 of the target natural hair GM can engage with the engagement member 20. This ensures that the target natural hair GM can be separated from the other natural hairs, improving the efficiency of the hair extension work.

Furthermore, if the end face FM of the edge of the opening 10X facing the worker is vertical, the edge of the opening 10X will block the hair roots MK at the worker's line of sight ML. Therefore, it is preferable that the end face FM is slanted from the bottom to the top so that it is away from the worker's line of sight ML, which passes through the hair roots MK. This makes it easier for the worker to see the hair roots MK of the natural hair GM, improving the efficiency of the hair extension work.

The engaging member 20 is formed in a plate shape and extends so as to protrude from the X-direction end of the pressing member 10 toward the Z-direction. The engaging member 20 is formed in a rectangular shape extending in the Z-direction and the Y-direction. The height H20 of the engaging member 20 in the Z-direction may be such that the coated portion GM1 stands up when the tip portion GM2 engages. The coated portion GM1 may be set appropriately according to the purpose, but is preferably, for example, 5 mm or less from the hair root MK. In addition, it is preferable that the opening 10X extends longer in the Y-direction than in the X-direction. For example, the length of the opening 10X is preferably 1 mm to 2 mm in the X-direction and 3 cm to 6 cm in the Y-direction, and more preferably 4 cm to 4.5 cm. This makes it difficult for the natural hair GM that passes through the opening 10X to overlap each other at the upper end of the engaging member 20, improving the efficiency of the hair-augmenting work. For this reason, it is preferable that the opening 10X extends in an elongated manner in the Y-direction.

It is also preferable that the holding member 10 has an identifier for the coated part GM1. In this embodiment, the ridge 10XS on the side of the edge of the opening 10X opposite the worker serves as the identifier for the coated part GM1. Note that in FIG. 2, the upper ridge 10XS serves as the identifier for the coated part GM1, but the present invention is not limited to this. The lower ridge may serve as the identifier for the coated part GM1, or a scale or mark serving as an identifier may be provided appropriately on the edge of the opening 10X.

The hook member 30 is preferably provided on the upper part of the engagement member 20. The hook member 30 may be any member that can engage with the natural hair GM engaged with the engagement member 20. For example, it is preferable to use a hook-and-loop fastener having a hook portion F as the hook member 30 (Figure 3).

As shown in FIG. 1, it is preferable that horizontal slits SL are formed on both ends in the Y direction at the connection portion between the pressing member 10 and the engaging member 20. In addition, a hairpin HP can be inserted through the horizontal slits SL to pinch the pressing member 10 and the surrounding natural hair.

The material from which the hair growth support tool 2 is made may be either hard or soft. The material from which the holding member 10 is made is preferably soft enough to be deformed to fit the shape of the head. The material from which the engaging member 20 is made is preferably rigid enough to maintain a predetermined position. For example, the material from which the hair growth support tool 2 is made may be metal, wood, bamboo, or plastic (e.g., silicone resin), and any of these may be used.

Next, we will explain the hair growth method 100 using the hair growth work support tool 2.

(Hair extension method)
As shown in FIG. 4, the hair growth method 100 includes an alignment step S110 for aligning the hair growth work support jig 2, a passing step S120 for passing the natural hair GM through the opening 10X, a placement step S130 for placing the hair growth work support jig 2 on the head so as to suppress the surrounding natural hair growing around the natural hair GM, an erection step S140 for erecting the coated portion GM1 of the natural hair GM, a temporary fixing step S150 for temporarily fixing the artificial hair EX to the coated portion GM1 of the natural hair GM, and an adhesion step S160 for adhering the artificial hair EX to the coated portion GM1.

Here, the temporary fixing step S150 includes a temporary fixing agent application step S152 in which a temporary fixing agent is applied to the base end portion of the artificial hair EX, and a contact step S154 in which the natural hair GM and the artificial hair EX are brought into contact with each other via the temporary fixing agent.

The adhesion step S160 includes an adhesive application step S162 in which adhesive is applied, and an adhesive curing step S164 in which the adhesive applied to the adhesive application portion GM1 is cured.

(Temporary adhesive)
The temporary bonding agent may be a cyanoacrylate-based temporary bonding agent, which contains a component represented by the following formula:
_CH2 =C(CN)COOR
wherein R is selected from an alkyl group, an alkoxyalkyl group, a cycloalkyl group, a haloalkyl group, an alkenyl group, an alkynyl group, an arylalkyl group, and an aryl group.

Cyanoacrylate-based temporary adhesives come in a variety of types, including methyl-based (methyl cyanoacrylate), ethyl-based (ethyl cyanoacrylate), butyl-based (butyl cyanoacrylate), octyl-based (octyl cyanoacrylate), methoxy-based (methoxyethyl cyanoacrylate), and ethoxy-based (ethoxyethyl cyanoacrylate), and any of these can be used. Blends of these in a specified ratio can also be used.

Next, we will explain temporary adhesives other than cyanoacrylate-based temporary adhesives.

It is preferable that the adhesive component of the temporary fixing agent contains a polymer that satisfies the cosmetic standards. "Cosmetic standards" are specific regulations on the ingredients that are formulated in cosmetics based on the Pharmaceutical Affairs Law to ensure that cosmetics do not pose health and hygiene hazards. In the present invention, "polymers that meet the cosmetic standards" are polymers that do not violate the provisions of the above cosmetic standards, and refer to, for example, polymers whose formulation is not prohibited by the "cosmetic standards" established in Ministry of Health, Labor and Welfare Notification No. 331 of 2000.

As a polymer that satisfies the cosmetic standards, it is preferable to include a water-soluble polymer. Examples of such water-soluble polymers include polyvinylpyrrolidone, polyvinyl alcohol, hydroxypropyl cellulose, hydroxyethyl cellulose, highly polymerized polyethylene glycol, cellulose gum, sodium acrylate grafted starch, gum arabic, xanthan gum, guar gum, gellan gum, cellulose gum, rice starch, tapioca starch, agar, alginic acid, and carrageenan. As the water-soluble polymer, it is preferable to use polyvinylpyrrolidone and/or cellulose gum, and it is particularly preferable to use polyvinylpyrrolidone. These water-soluble polymers can be used alone or in combination of two or more.

The content of the polymer that meets the cosmetic standards is preferably 20 to 80% by mass, more preferably 30 to 70% by mass, and particularly preferably 40 to 60% by mass, relative to the temporary fixing agent. For example, when polyvinylpyrrolidone and cellulose gum are used as the polymer that meets the cosmetic standards, the content of polyvinylpyrrolidone is preferably 20 to 40% by mass relative to the temporary fixing agent.

(glue)
The adhesive contains a photocurable component and a photopolymerization initiator.

There are no particular limitations on the photocurable component, and various types can be used. Common photocurable components include (meth)acrylic acid derivatives such as (meth)acrylic acid esters, and their oligomers and polymers. Examples of (meth)acrylic acid derivatives include methyl (meth)acrylate, ethyl (meth)acrylate, 2-ethylhexyl (meth)acrylate, 2-hydroxyethyl (meth)acrylate, 2-hydroxypropyl (meth)acrylate, 2-hydroxyethyl (meth)acrylamide, ethylene glycol di(meth)acrylate, triethylene glycol di(meth)acrylate, tetraethylene glycol di(meth)acrylate, propylene glycol di(meth)acrylate, trimethylolpropane tri(meth)acrylate, tetra ... tetra( ) acrylate, tetramethylolpropane tetra(meth)acrylate, pentaerythritol tri(meth)acrylate, pentaerythritol tetra(meth)acrylate, dipentaerythritol penta(meth)acrylate, dipentaerythritol hexa(meth)acrylate, 1,6-hexanediol di(meth)acrylate, isobornyl acrylate, benzyl (meth)acrylate, cardo epoxy di(meth)acrylate, N,N'-methylenebisacrylamide, urethane acrylate, etc.

Examples of photopolymerization initiators include 1-hydroxycyclohexyl phenyl ketone; benzophenone, 4,4'-bis(dimethylamino)benzophenone, 3,3-dimethyl-4-methoxy-benzophenone and other benzophenone derivatives; anthraquinone, 2-methylanthraquinone, 2-ethylanthraquinone, tert-butylanthraquinone and other anthraquinone derivatives; benzoin, benzoin methyl ether, benzoin ethyl ether, benzoin propyl ether and other benzoin alkyl ether derivatives; 2-chlorothioxanthone, diethylthioxanthone, isopropylthioxanthone, diisopropylthioxanthone and other thioxanthone derivatives; acetophenone, 2,2-dimethoxy-2-phenylacetophenone, 2,2-diethoxyacetophenone, 2 -Acetophenone derivatives such as hydroxy-2-methylpropiophenone, 4'-isopropyl-2-hydroxy-2-methylpropiophenone, and 2-methyl-1-[4-(methylthio)phenyl]-2-morpholino-1-propane; Michler's ketone, 2,4,6-(trihalomethyl)triazine, 2-(o-chlorophenyl)-4,5-diphenylimidazolyl dimer, 9-phenylacridine, 1,7-bis(9-acridinyl)heptane, 1,5-bis(9-acridinyl)pentane, 1,3-bis(9-acridinyl)propane, dimethylbenzyl ketal, trimethylbenzoyldiphenylphosphine oxide, tribromomethylphenyl sulfone, and 2-benzyl-2-dimethylamino-1-(4-morpholinophenyl)-butan-1-one.

The adhesive may further contain a colorant such as a pigment or dye. The colorant may be selected according to the user's preference.

The adhesive may further include solvents, fillers, defoamers, buffers, chelating agents, dispersants, preservatives, resin powders, thickeners, wetting agents, and plasticizers.

(Alignment step)
In the positioning step S110, the hair growth work support jig 2 is positioned on the head so that the opening 10X overlaps with the target natural hair GM.

(Through Step)
In the passing step S120, the target natural hair GM is passed through the opening 10X. The passing step S120 may be performed after the placing step S130, but is preferably performed before the placing step S130 in terms of work.

(Placement Step)
In the placement step S130, the hair growth work support jig 2 is placed at the position set in the positioning step S110. This allows the surrounding natural hair growing around the target natural hair GM to be laid down while the target natural hair GM passes through the opening 10X. Also, a hairpin is inserted from the horizontal slit SL to pinch the holding member 10 and the surrounding natural hair. This fixes the hair growth work support jig 2 from the head, improving work efficiency and preventing the hair growth work support jig 2 from falling off.

(Standing up step)
In the standing step S140, the tip portion GM2 of the natural hair GM is placed on the upper end of the engagement member 20. As a result, the tip portion GM2 engages with the engagement member 20, and the application target portion GM1 on the root side stands up. At this time, the tip portion GM2 engages with the hook member 30, making it possible to position the tip portion GM2 in the Y direction. This prevents the tip portion GM2 from moving unintentionally, stabilizing the posture of the application target portion GM1 on the root side, thereby improving the work efficiency from the temporary bonding agent application step S152 onwards.

(Temporary adhesive application step)
In the temporary bonding agent application step S152, the temporary bonding agent is applied to the base end portion of the artificial hair EX. First, the temporary bonding agent is placed on a sheet. Next, the base end portion of the artificial hair EX is brought into contact with the temporary bonding agent on the sheet. As a result, the temporary bonding agent KS is applied to the base end portion EX1 of the artificial hair EX (FIG. 5(A)). Note that the method of applying the temporary bonding agent is not limited to the above-mentioned method, and a known tool such as a brush may be used.

(Contacting Step)
In the contact step S154, the base end portion EX1 of the artificial hair EX to which the temporary fixing agent KS is applied is brought into contact with the application portion GM1 (FIG. 5(B)). As a result, the artificial hair EX (FIG. 1) is temporarily fixed to the application portion GM1. The artificial hair EX includes a plurality of filaments, and the base end portions of the filaments are integrated with each other. The diameter of the filaments is not particularly limited, but is preferably 0.1 mm or more and 2 mm or less, and more preferably 0.2 mm or more and 1 mm or less. The length of the filaments is not particularly limited, but is preferably 10 mm or more and 30 mm or less. The material of the filaments is not particularly limited, and known materials such as plastics can be used. The artificial hair EX may be a single filament.

In addition, human hair may be used instead of the artificial hair EX.

(Adhesive application step)
In the adhesive application step S162, adhesive is applied to the artificial hair EX and the natural hair GM. It is preferable to apply the adhesive so as to cover the artificial hair EX and the applied part GM1 to which the temporary fixing agent has been applied. Also, as for the part to which adhesive is applied, adhesive may be applied not only to the part temporarily fixed by the temporary fixing agent, as shown by the dashed line part SS in Fig. 5(C), but also to the entire periphery of the base end part EX1 of the artificial hair EX and the applied part GM1. In particular, it is preferable to apply the adhesive so that the step part of the base end part EX1 of the artificial hair EX relative to the natural hair GM becomes smooth. A known tool such as a brush can be used to apply the adhesive.

When applying a temporary fixing agent or adhesive to the application portion GM1, it is preferable to use the ridge 10XS of the opening 10X as an identifier of the application portion GM1. In other words, it is preferable to set the area between the hair root MK and the ridge 10XS of the opening 10X as the application area from the worker's perspective, and apply the temporary fixing agent or adhesive to that area. This allows the application position of each hair to be aligned.

(Adhesive curing step)
In the adhesive curing step S164, a light source is used to irradiate the applied adhesive with a predetermined amount of light. The light source may be, for example, a UV (ultraviolet) lamp, a UV-LED, a visible light LED, or an infrared lamp.

The preferred wavelength of the light source is not particularly limited as long as it cures the adhesive, and any of the following can be used: ultraviolet light, visible light, infrared light, etc. From the viewpoint of ease of handling, it is preferable to use visible light (wavelength range: 360 nm or more and 830 nm or less).

When a predetermined light is applied to the applied adhesive, it is preferable that the holding member 10 has a light-shielding property against the wavelength of the light in order to block the light from traveling toward the scalp. For example, the holding member 10 may be formed from a material that has a light-shielding property against the wavelength of the light, or a sheet made of a material that has a light-shielding property against the wavelength of the light may be formed on the holding member 10. There are no particular limitations on the material that has a light-shielding property. For example, when the light source is visible light, examples of the material that has a light-shielding property include carbon black, acetylene black, lamp black, graphite, aniline black, calcium carbonate, talc, kaolin, titanium oxide, zinc oxide, and zinc oxide. In addition, when the light source is ultraviolet light, a known ultraviolet absorber may be used, and when the light source is infrared light, a known infrared absorber may be used.

After the adhesive application step S162 is completed, the alignment step S110 to adhesive application step S162 are performed on the new target natural hair GM. By repeating this process, the adhesive application work of adhering artificial hair to the desired natural hair can be performed.

According to the present invention, the temporary fixing step and the adhesion step are performed in this order, so that the adhesion period between the natural hair GM and the artificial hair EX is extended compared to the case where only the temporary fixing step is performed. Here, when the temporary fixing step and the adhesion step are performed, the adhesion force lasts for about six weeks, but when only the temporary fixing step is performed, the adhesion force lasts for only about three weeks. Of course, when only the adhesion step is performed, the adhesion force lasts for about six weeks, but the adhesion step requires two steps, an adhesive application step and an adhesive hardening step. Therefore, there is a possibility that the natural hair GM and the artificial hair EX may become misaligned before the adhesive hardens. In order to avoid such a situation, it is necessary to fix both the natural hair GM and the artificial hair EX in order to maintain the relative positional relationship between them until the adhesive hardens. As in the present invention, the temporary fixing step is performed prior to the adhesion step, so in the temporary fixing step, the natural hair GM and the artificial hair EX are temporarily fixed immediately after the application of the temporary fixing agent. Therefore, in the adhesion step, there is no need to fix the natural hair GM and the artificial hair EX until they are adhered to each other. In this way, according to the present invention, the hair extension work can be easily performed and the adhesive strength can be maintained for a long period of time.

In the above embodiment, a hair growth support tool 2 was used in which the holding member 10, the engagement member 20, and the hook member 30 were integrated, but the present invention is not limited to this, and each member may be separate.

In the above embodiment, for example, a hook-and-loop fastener having a hook portion F is used as the hook member 30, but the present invention is not limited to this, and the hook member 30 may be formed from a material that is adhesive to natural hair. Examples of materials that are adhesive to natural hair include silicone resin.

In the above embodiment, an opening 10X is formed in the pressing member 10, but the present invention is not limited to this. For example, the hair growth work support jig 2 shown in FIG. 6 does not have an opening 10X formed in the pressing member 10. In this case, the ridge line 10XS of the end face of the pressing member 10 becomes the identifier of the applied portion GM1.

In addition, in the temporary fixing step S150, after applying a temporary fixing agent to the natural hair GM (e.g., the application target portion GM1), the base end portion of the artificial hair EX may be brought into contact with the application target portion GM1 to which the temporary fixing agent has been applied.

In the above embodiment, the hair augmentation method 100 includes a temporary fixing step S150 in which the artificial hair EX is temporarily fixed to the applied portion GM1 of the natural hair GM, but the present invention is not limited to this. If the adhesive contains a temporary fixing component, the temporary fixing step S150 may be omitted. In such a case, in the adhesive application step S162, the procedure for applying adhesive to the artificial hair EX and the natural hair GM may be, as in the above-mentioned temporary fixing step S150, to bring the base end portion of the artificial hair EX into contact with the adhesive on the sheet and then bring the base end portion of the artificial hair EX into contact with the applied portion GM1, or to apply adhesive to the applied portion GM1 and then bring the base end portion of the artificial hair EX into contact.

In the above embodiment, the hair growth method 100 uses a hair growth work support jig 2, but the hair growth method of the present invention is not limited to this and may be performed without using the hair growth work support jig 2.

The present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention.
