Description

[Technical Field]

[0001] The present invention relates to a method for applying eyelashes to achieve desired length and curl. [Background technology]

[0002] Since eyelashes are one of the important elements that determine the impression of the eyes, in order to achieve cosmetic effects, eyelash perm treatments are performed, which change the impression of the eyes by lifting and curling the eyelashes from the root, and eyelash extension treatments are performed, which attach artificial hair (extensions) to the eyelashes to change the volume and length of the eyelashes and make the eyes look more glamorous.

[0003] Furthermore, in order to further enhance the cosmetic effect, there is a treatment method described in Patent Document 1, for example, which performs both the eyelash perm treatment and eyelash extension treatment described above.

[0004] Patent Document 1 describes a method of attaching artificial hair to the upper eyelashes, then fixing the upper eyelashes with the attached artificial hair on the top surface of a curling rod, applying a first agent containing a reducing agent (referred to as the "first curling agent" in Patent Document 1) to areas near the base of the upper eyelashes where no artificial hair is present, and then applying a second agent containing an oxidizing agent (referred to as the "second curling agent" in Patent Document 1) to the areas where the first agent has been wiped off, thereby forming a resilient, permanent curl near the base of the upper eyelashes. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] JP 2023-58812 A Summary of the Invention [Problem to be solved by the invention]

[0006] The procedure for attaching artificial hair to the eyelashes described above involves placing the artificial hair approximately 1 mm away from the base of the eyelashes, along the extension direction of the eyelashes, with a diameter of 0.1 to 0.15 mm, and applying adhesive to the area where the artificial hair comes into contact with the eyelashes to attach the artificial hair to the eyelashes.

[0007] In other words, since the treatment is performed in an extremely small, limited area, even if the first or second agent is applied to the area near the base of the eyelashes where no artificial hair is present, as described in Patent Document 1, in reality, the first or second agent is applied to both the eyelashes and the artificial hair.

[0008] However, when artificial hair is attached to the upper eyelashes, a step occurs at the boundary between the artificial hair and the actual eyelashes. As a result, when the first agent is applied, the first agent pools at this step, causing the eyelashes to be reduced more than necessary to achieve the desired effect, resulting in damage to the eyelashes.

[0009] Furthermore, the effects of eyelash treatment can only be maintained for a certain period of time because the artificial hairs can fall off and the curl position can shift due to the cyclical growth of the eyelashes. Therefore, users often undergo repeated treatments periodically in pursuit of cosmetic effects. For example, if eyelash extensions are performed on eyelashes that have not yet been permed, the remaining curl on the eyelashes may prevent the artificial hair from being attached to the desired position. Additionally, if a user's own eyelashes are curly, this can make it difficult to attach the artificial hair to the desired position, or the artificial hair may fall off prematurely.

[0010] Furthermore, while Patent Document 1 describes a method of performing a perm after eyelash extensions, there are also methods of performing eyelash extensions after a perm. However, performing an eyelash perm followed by extensions means that the extensions are attached to curled eyelashes. In this case, it is difficult to attach the extensions to curled eyelashes, and the tips of the eyelashes and the extensions may be positioned in different directions, resulting in an unattractive appearance.

[0011] The main object of the present invention is to provide a treatment method that does not damage the eyelashes when performing both eyelash perm treatment and eyelash extension treatment, and that can form eyelashes into a desired shape even if they have residual eyelashes from a previous treatment or are curly, and that can form eyelashes with reduced variation and good appearance. [Means for solving the problem]

[0012] In order to achieve the above object, the eyelash treatment method of the present invention is characterized by comprising a first step of applying a first agent containing a reducing agent to the eyelashes, a second step of wiping off the first agent applied to the eyelashes, a third step of attaching and fixing artificial hair for extensions to the eyelashes, a fourth step of temporarily placing the eyelashes with the attached and fixed artificial hair on a temporary placement member, and a fifth step of applying a second agent containing an oxidizing agent to the eyelashes with the attached and fixed artificial hair temporarily placed on the temporary placement member.

[0013] In one specific embodiment of the eyelash treatment method of the present invention, the first step involves applying a gel-like first protective agent to the eyelashes before applying the first agent to the eyelashes.

[0014] In one specific embodiment of the eyelash treatment method of the present invention, the second step involves wiping the first agent from the eyelashes and then applying a gel-like second protective agent to the eyelashes.

[0015] In one specific embodiment of the eyelash treatment method of the present invention, at least one of the first agent and the second agent does not contain an alkaline component.

[0016] A specific embodiment of the eyelash treatment method of the present invention is one in which, in the third step, when multiple artificial hairs are attached to one eyelash, the temporary placement member includes an inclined member having an inclined surface. [Effects of the Invention]

[0017] According to the eyelash treatment method of the present invention, in the first step prior to the third step of attaching artificial eyelashes to the eyelashes, the first agent containing a reducing agent is applied to the eyelashes, so that the first agent is applied only to the natural eyelashes. As a result, there are no uneven areas caused by attaching artificial eyelashes, and the first agent can be applied evenly to the eyelashes, preventing excessive reduction in only one area due to liquid pooling and preventing damage to the eyelashes.

[0018] In addition, in the first step, the reducing action of the first agent breaks the cystine bonds in the keratin molecules of the eyelashes, softening them, making it possible to straighten out lashes that still have curls from the previous treatment or that are curly.In the third step, artificial hair extensions are attached and fixed to the lashes in this state, allowing the artificial hair to be attached in the desired position.

[0019] In addition, since the third step, which is the eyelash extension treatment, is carried out between the first step and the fifth step, which are the eyelash perm treatments, it is possible to attach artificial hairs to the lashes that have not yet been curled, which have only been restored by the first agent in the first step. Therefore, the artificial hairs can be attached to the lashes and arranged so that the extension directions of the lashes and the artificial hairs are in the same direction, making it possible to create eyelashes with a good appearance and reduced variation.

FIG. DETAILED DESCRIPTION OF THE INVENTION

[0021] An embodiment of the eyelash treatment method of the present invention will be described in detail below with reference to the drawings.

[0022] 1, the eyelash treatment method of this embodiment includes a first step of applying a first agent containing a reducing agent to the eyelashes 2, a second step of wiping off the first agent applied to the eyelashes 2, a third step of attaching and fixing artificial hairs 3 for extensions to the eyelashes 2, a fourth step of temporarily placing the eyelashes 2 with the attached and fixed artificial hairs 3 on a temporary placement member 4, and a fifth step of applying a second agent containing an oxidizing agent to the eyelashes 2 with the attached and fixed artificial hairs 3 that have been temporarily placed on the temporary placement member 4. Note that, for the sake of explanation, the following assumes that the treatment is performed on upper eyelashes (hereinafter referred to as "eyelashes 2"), but a similar treatment may also be performed on lower eyelashes.

[0023] <Pretreatment> As a pre-treatment for the first step, protective tape 1 is applied to the lower eyelashes as shown in Figure 2. This is a treatment to prevent the lower eyelashes from getting caught in the third step, in which artificial hair 3 is attached to the eyelashes 2.

[0024] Next, with the lower eyelashes protected, the eyelashes 2 are washed with alkaline ionized water to remove sebum, dirt, etc. from the eyelashes 2. This allows the repulsive action of the negative electrons contained in the ionized water to remove sebum and dirt, and also allows hydrogen ions to penetrate the eyelashes 2, increasing the moisture content of the eyelashes 2 and making it easier for the medicinal solutions of the first and second agents described below to penetrate.

[0025] <First step> Thereafter, the first step is performed in which the first agent containing a reducing agent is applied to the eyelashes 2. First, the first protective agent is applied to the eyelashes 2 with absorbent cotton, a rod, or the like placed under the eyelashes 2 to prevent the medicine from getting into the eyes.

[0026] The first protective agent is a viscous gel containing ingredients such as rice bran oil, squalane, jojoba oil, fumaric acid, various amino acids, cationic oil keratin, anionic cellulose, polymeric chitosan, and hydrolyzed silk. Because the first protective agent is in gel form, it adheres closely to the eyelashes 2, and the ingredients mentioned above bond with the amino acids inside the eyelashes to repair damaged areas and protect the eyelashes 2. Therefore, applying the first protective agent repairs and protects the eyelashes 2, preventing damage to the eyelashes 2.

[0027] The first agent is applied to the eyelashes 2 to which the first protective agent has been applied. This first agent may contain any reducing agent as long as it does not contain an alkaline component, such as cysteamine or thioglycolic acid, but the components of the first agent are not limited to these. In this embodiment, the first agent is configured to have viscosity. The eyelashes 2 to which the first agent has been applied are softened by the reducing action of the first agent, which breaks the cystine bonds of the keratin molecules in the eyelashes. In order to obtain the softness required for the treatment, the eyelashes 2 are left with the first agent applied for a predetermined time (approximately 10 minutes in this embodiment).

[0028] <Second process> After the aforementioned predetermined time has elapsed, a second step is performed to remove the first agent applied to the eyelashes 2. To remove the first agent applied to the eyelashes 2, the eyelashes 2 are wiped with the alkaline ionized water used in the pretreatment, thereby stopping the reducing effect on the eyelashes 2. The eyelashes 2 are then wiped again with a wiping lotion containing hematin. This wipes off any remaining first agent on the eyelashes 2 that could not be wiped off with the ionized water, preventing damage to the eyelashes 2 caused by the remaining first agent and preventing the remaining first agent from inhibiting the recombination of cystine bonds in keratin molecules in the fifth step.

[0029] The second protective agent is then applied. The second protective agent is gel-like and viscous, and contains ingredients such as keratin (activated keratin, cashmere keratin, cationic oil keratin, etc.), anionic cellulose, polymeric chitosan, various amino acids, rice bran oil, squalane, and jojoba oil. Because the second protective agent is also gel-like, it adheres to the eyelashes 2, allowing the aforementioned ingredients to penetrate, repairing damaged areas and protecting the eyelashes 2. Therefore, the second protective agent not only repairs the eyelashes 2, but also protects the eyelashes 2 from the adhesive for the artificial hair 3 used in the third step and the second agent used in the fifth step, thereby preventing damage to the eyelashes 2.

[0030] Furthermore, after wiping off the first agent and applying the second protective agent, the eyelashes 2 are shampooed. Dry wiping may be performed instead of shampooing. Shampooing and dry wiping return the eyelashes 2 to a state where they are free of foreign matter and oil, making it easier to attach the artificial hairs 3 for extensions.

[0031] <Third process> Next, the artificial hairs 3 for extensions are attached and fixed to the eyelashes 2. In this embodiment, an adhesive that hardens through a photopolymerization reaction caused by ultraviolet light is used as the attachment and fixing method, but this attachment and fixing method is not limited to this. In addition, the single lash method and the volume lash method will be described below as examples of methods for attaching the artificial hairs 3 to the eyelashes 2, but the method for attaching the artificial hairs 3 to the eyelashes 2 is not limited to these methods, and the practitioner can freely select any method, such as the bind lock method, as appropriate.

[0032] For the sake of explanation, the inside of the curve of the eyelashes 2 and artificial hairs 3 that curve toward the upper eyelid will be referred to as the front side, and the outside of the curve as the back side. The eyelashes 2 and artificial hairs 3 are configured to extend in a curve from the base, gradually tapering in diameter. The end that tapers will be referred to as the tip, and the other end that is positioned near the eye will be referred to as the base.

[0033] In this embodiment, an adhesive that hardens when exposed to ultraviolet light is used, so before the process of attaching the artificial hair 3, a protective sheet (not shown) for blocking ultraviolet light is placed on the upper eyelid in the area to be irradiated with ultraviolet light (especially to prevent ultraviolet light from reaching the eyeball), but this process can be modified as appropriate depending on the adhesive used.

[0034] Single lash method As shown in FIG. 3, this method can create a bunched look on the eyelashes 2, and involves attaching one single artificial lash 3a to each eyelash.

[0035] The single lash artificial hairs 3a have approximately the same diameter as the eyelashes 2 and are positioned approximately 1 mm away from the base of the eyelashes 2. At this time, as shown in Figure 4, the front surface of the single lash artificial hairs 3a is brought into contact with the back surface of the eyelashes 2 so that the extension directions of the eyelashes 2 and the single lash artificial hairs 3a match. The practitioner fine-tunes the position of the single lash artificial hairs 3a, and after adjustment, applies ultraviolet light to harden them, and then attaches the single lash artificial hairs 3a to the eyelashes 2.

[0036] Volume lash method As shown in FIG. 6, this method can increase the volume of eyelashes 2 by attaching a plurality of artificial hairs 3b for volume lashes to each eyelash.

[0037] The artificial bristles for volume lashes 3b have a diameter thinner than the eyelashes 2, and multiple artificial bristles for volume lashes 3b are placed around the lashes 2, approximately 1 mm away from the base of the eyelashes 2. At this time, as shown in Figure 7, the surfaces of the artificial bristles for volume lashes 3b are brought into contact with the circumferential surface of the eyelashes 2 so that the extension directions of the eyelashes 2 and the artificial bristles for volume lashes 3b match. The practitioner fine-tunes the positions of the artificial bristles for volume lashes 3b, and after adjustment, applies ultraviolet light to harden them, and then attaches the artificial bristles for volume lashes 3b to the eyelashes 2.

[0038] <Fourth step> The fourth step is to temporarily place the eyelashes 2 to which the artificial hairs 3 have been attached in the third step on a temporary placement member 4. In this fourth step, the eyelashes 2 to which the artificial hairs 3 have been attached are temporarily placed on the temporary placement member 4 so that they have the desired shape (curled from the root). First, before being temporarily placed on the temporary placement member 4, the eyelashes 2 to which the artificial hairs 3 have been attached are curled with a hot curler. The subsequent steps differ between the single lash method and the volume lash method, and will be explained separately.

[0039] Single lash method In the single lash method, as shown in Figure 5, a rod 4a is used as a temporary holder 4, and the eyelashes 2, to which single lash artificial hairs 3a are attached and fixed, are wound around the rod 4a to create curls. Here, a natural look is achieved by aligning the outline of the base of the eyelashes 2 (the hairline of the eyelashes 2), so the practitioner adjusts the degree of curling around the rod 4a to align the outline.

[0040] Volume lash method In the volume lash method, as shown in Figure 8, a tilted member 4b with a tilted surface 5 is used as the temporary holder 4, and eyelashes 2 with attached and fixed volume lash artificial hairs 3b are placed along the tilted surface 5. For example, absorbent cotton is placed upright and at an angle relative to the face as the tilted member 4b, with tape or the like placed on the back surface opposite the tilted surface 5 to prevent the absorbent cotton from tipping over, as a fastening member 6. Even with the volume lash method, aligning the outline of the base of the eyelashes 2 (the hairline of the eyelashes 2) creates a natural look, so the practitioner adjusts the curl to align the outline. While this embodiment uses a tilted member 4 as the temporary holder 4, a rod may also be used.

[0041] <5th step> After the eyelashes 2 with the artificial hairs 3 attached and fixed thereto are temporarily placed on the temporary placement member 4 and adjustment is completed, a fifth step is carried out in which the second agent containing an oxidizing agent is applied.

[0042] The second agent may contain any oxidizing agent as long as it does not contain an alkaline component, such as sodium bromate or hydrogen peroxide, but the components of the second agent are not limited to these. In this embodiment, the second agent is also configured to be viscous. When the second agent is applied to the eyelashes 2, the oxidizing action of the second agent recombines the cystine bonds of the keratin molecules that were cut by the first agent. At this time, the eyelashes 2 with the artificial hairs 3 attached are temporarily placed on the temporary placement member 4 in the fourth step and adjusted to have the desired shape. Therefore, the cystine bonds recombine in this adjusted state, allowing the eyelashes 2 with the artificial hairs 3 attached to form the desired shape (curl).

[0043] After the second agent has been applied and left for a specified time (approximately 10 minutes), it is wiped off using the alkaline ionized water used in the pre-treatment.The second protective agent is then applied again, shampooed or wiped dry, and any final adjustments or coatings are applied.

[0044] The eyelash treatment method configured as above has the following special effects.

[0045] That is, in the first step, before the third step of attaching the artificial hair 3 to the eyelashes 2, the first agent containing a reducing agent is applied to the eyelashes 2. Here, since the artificial hair 3 is not attached in the first step, there is no step at the boundary between the artificial hair 3 and the eyelashes 2, and the first agent can be applied evenly to the eyelashes 2. Therefore, excessive reduction action does not occur in only one area due to liquid accumulation, and damage to the eyelashes 2 can be prevented.

[0046] Furthermore, in the first step, without the artificial hairs 3 attached, the reducing action of the first agent breaks the cystine bonds of the keratin molecules in the eyelashes to soften them, so even if the eyelashes 2 still have the remains of a previous treatment or are curled, the eyelashes 2 can be made curl-free. In this state, in the third step, the artificial hairs 3 for extensions are attached and fixed to the eyelashes 2, so the artificial hairs 3 can be attached in the desired position and the artificial hairs 3 can be prevented from falling off in a short period of time.

[0047] Furthermore, since the third step, which is the eyelash extension treatment, is carried out between the first step (reduction step) and the fifth step (oxidation step), which are the eyelash perm treatments, the artificial hairs 3 can be attached to the eyelashes 2 that have not been curled and have only been reduced by the first agent (reducing agent). This allows the practitioner to more easily attach the artificial hairs 3 to the eyelashes 2, and by arranging the extension directions of the eyelashes 2 and the artificial hairs 3 in the same direction, it is possible to form eyelashes 2 with a good appearance and reduced variation.

[0048] With the above-described configuration, the eyelash treatment method of the present invention can perform both eyelash perm treatment and eyelash extension treatment without limiting the method of attaching the artificial hairs 3 to the eyelashes 2.

[0049] In addition, because the first and second protective agents are gel-like and viscous, they adhere to the eyelashes 2, allowing their ingredients to penetrate more easily, repairing and protecting the eyelashes 2 while preventing damage to the eyelashes 2. Furthermore, because the first and second agents are also viscous, the reducing action of the first agent and the oxidizing action of the second agent can be applied more effectively.

[0050] When the first or second agent contains an alkaline component, the volatile components contained in the alkaline component react with the adhesive (glue), resulting in a problem of poor adhesion of the artificial hair. In particular, in the past, when performing eyelash perm treatments, glue was also applied to the rod to wrap the eyelashes around it. Therefore, the glue reacts with the volatile components of the alkaline components contained in the first and second agents, resulting in a poor adhesion of the artificial hair. However, in the present invention, neither the first nor the second agent contains an alkaline component, which prevents the deterioration of the adhesion of the artificial hair 3 and prevents the artificial hair 3 from coming off prematurely.

[0051] In addition, in the present invention, the first agent (reducing agent) in the first step breaks the cystine bonds in the eyelashes 2, softening them and making them easier to manage for the practitioner. This allows the practitioner to position the eyelashes 2 at the desired position on the temporary holder 4 and lift them from the roots without using glue as in the past.

[0052] The first protective agent, second protective agent, first agent and second agent are not limited to gel forms, and may be used in appropriate forms such as creams and liquids.

[0053] The present invention is not limited to the above-described embodiments, and various improvements, modifications, or variations based on the knowledge of those skilled in the art can be made without departing from the spirit of the present invention. Furthermore, the present invention can be embodied in a form in which any of the inventive features is replaced with other technology within the scope of producing the same function or effect.
