Description

Perm treatment method for minimizing hair damage {Procedure Method for Minimizing Hair Damage}

The present invention relates to a method of performing a perm by minimizing damage to the hair while restoring the state of the hair so that the perm operation can be performed even if the hair is already damaged.

Keratin is a fibrous protein polymer composed of about 18 amino acids such as cysteine, glutamic acid, and arginine, and is the main component of hair. Keratin has the highest content of cysteine among amino acids, and forms a cross-linked structure having one disulfide bond (-S-S-) per 10 to 20 amino acid residues on average. Keratin is not soluble in water and neutral solvents and is not easily affected by proteolytic enzymes such as pepsin, but is weak to sodium sulfide, thioglycolic acid, hydrogen peroxide, and alkali, which break disulfide bonds. Using these characteristics of keratin, a perm composition (permanent waving agent) used to form waves in hair consists of a perm agent containing a reducing agent as a main component and a neutralizing agent containing an oxidizing agent as a main component.

The principle of hair perm is to cut the disulfide bond of cystine [HO2CC(NH2)HCH2SSCH2C(NH2)HCO2H] using a reducing agent to reduce it to cysteine [HO2CC(NH2)HCH2SH] to transform the appearance of the hair (perm treatment) step), after or simultaneously with such treatment, applying mechanical tensile force (and heat) to the hair to form waves in the hair using a roller or curler, etc. to maintain the wavy shape (wave forming step), and using an oxidizing agent to One reaction is reversed to convert cysteine back to cystine, thereby fixing the hair to a wavy shape (neutralizing agent treatment step).

The reducing agent used at this time, including thioglycolic acid and its esters, provides excellent reducing ability for hair binding, while inflicting strong damage to the hair, causing the hair to become brittle or split and break. The oxidizing agent mainly uses an aqueous hydrogen peroxide solution with high oxidizing power, but it is highly toxic and can damage hair and scalp. Since the hair may be damaged by such a perm composition, it is not suitable to apply a new perm procedure to already damaged hair, and there is a problem that the perm treatment must be performed with a certain amount of damage even with healthy hair.

Accordingly, the present inventor supplies sufficient protein to the hair in stages during the perm procedure and uses electrolytic reduced water to form a hydrophobic film on the hair surface to restore already damaged hair while minimizing the damage to the hair that occurs during the perm procedure, making it healthy. The present invention was completed by developing a method to keep the wave elastic with the hair condition.

The present invention comprises the steps of: a) heat-treating the hair by applying a liquid protein; b) applying a mixture of the perm agent and the complex protein; c) applying the liquid protein; d) applying electrolytic reduced water; e) washing and drying the hair; f) applying the complex protein; g) applying a perm to the hair; h) neutralizing the hair by applying a mixture of a neutralizing agent and complex protein; And i) an object of the present invention is to provide a perm treatment method for minimizing hair damage comprising the step of washing the hair.

Here, the liquid protein of step a) or c) may be composed of keratin protein, collagen protein and silk protein.

Step a) may be heat treatment at 40 to 60° C. for 5 to 20 minutes using a magic press or a dryer when applying liquid protein.

The complex protein of step b), step f) or step h) may include a protein or a derivative thereof, oil, or a plant extract.

The mixture of step b) may be a mixture of the pumping agent and the complex protein in a volume ratio of 7 to 9: 1 to 3.

The electrolytically reduced water in step d) may be used by mixing with the protein.

In step e), the hair may be washed with an acidic shampoo and dried.

The perm in step g) may be a wave perm or a straight perm.

The neutralizing agent in step h) may be hydrogen peroxide.

The mixture of step h) may be a mixture of a neutralizing agent and a complex protein in a volume ratio of 7 to 9: 1 to 3.

A perm treatment method for minimizing hair damage according to an embodiment of the present invention includes the steps of: a) applying a liquid protein to hair and heat-treating; b) applying a mixture of the perm agent and the complex protein; c) applying the liquid protein; d) applying electrolytic reduced water; e) washing and drying the hair; f) applying the complex protein; g) forming waves in the hair; h) neutralizing the hair by applying a mixture of a neutralizing agent and complex protein; and i) washing the hair.

Steps a) to i) of the manufacturing method will be described in detail as follows.

a) Heat treatment by applying liquid protein to the hair

Step a) is a process of supplying insufficient protein to the hair before the perm procedure.

Hair can be damaged not only by heat and chemical treatments such as perming and dyeing, but also by ultraviolet rays, static electricity, and fine dust. By supplying protein to the hair in advance before the perm procedure, it is possible to fill in the insufficient protein and reduce the degree of damage that occurs later.

The liquid protein may be composed of keratin protein, collagen protein and silk protein similar to hair components. The keratin protein is a protein that forms the basis of epithelial structures such as hair and skin, and fills empty spaces in damaged hair to make the hair smooth. The collagen protein and silk protein provide nutrition to the hair and scalp to give the hair shine. Such liquid protein may further include additives known in the art in addition to the protein component, for example, a surfactant, a moisturizer, a silicone polymer, a pH adjuster, a thickener, an oil, a fragrance, a colorant, a preservative, and the like.

In the process of applying the liquid protein, the liquid protein may be applied to the hair so that the protein component in the hair can be settled, and then heat-treated using a magic press or a dryer. For example, when applying liquid protein, press firmly using a hand or a magic press to firmly bond the hair and protein, and then apply heat to the hair through a hair dryer, mister, or roller ball to harden the protein to settle the protein inside the hair. can do it At this time, it is preferable to heat treatment at 40 to 60 ℃ for 5 to 20 minutes. If the temperature and time range are exceeded, the hair may be over-cured or burned by heat, which may rather damage the hair.

b) applying a mixture of the perm agent and the complex protein;

Step b) is a process of treating the hair with a perm agent while reducing damage to the hair using the complex protein.

The perm agent contains ammonia, thioglycosic acid, and the like, and it not only has a high content of reducing agent for a strong reducing action, but also causes severe damage to hair by creating a strong alkaline environment. To prevent hair damage, use a mixture of perm and complex protein.

The complex protein may include a protein or a derivative thereof, an oil, or a plant extract. The protein or its derivative may be at least one selected from the group consisting of keratin protein, collagen protein, silk protein, soy protein, egg white protein, milk protein, wheat protein, and derived proteins thereof that can fill the empty space in the hair. The oil may be a vegetable oil with little irritation to the hair and scalp, for example, argan oil, jojoba oil, coconut oil, camellia oil, rosehip oil, and the like. The plant extract can be used without limitation, plant extracts known in the art that can prevent static electricity generation by supplying nutrients to the hair surface and give a soft touch and shine, for example, licorice extract, Goji berry extract, tea tree extract, Angelica extract, bamboo shoot extract, jujube extract, peony extract, gardenia extract, sagebrush extract, pine needle extract, trifolieae extract, lotus leaf extract, perilla leaf extract, eoseongcho extract, injin mugwort extract, and the like. Such a complex protein may include 1 to 10% by weight of the protein or derivative thereof, 0.1 to 5% by weight of an oil, and 0.05 to 5% by weight of a plant extract based on the total weight.

In addition, the complex protein may further include additives known in the art, for example, a moisturizer, a silicone polymer, a pH adjuster, a thickener, an oil, a fragrance, a colorant, a preservative, and the like. In addition, the complex protein may be in the form of solutions, emulsions, lotions, creams, gels, aerosols, and the like, and as a component additionally used to maintain the formulation, materials known in the art may be used without limitation.

The application process of the mixture of the perm agent and the complex protein can be processed by adjusting the mixing ratio and leaving time according to the condition of the hair. For example, to healthy hair, apply a mixture of complex protein: perm agent = 1: 9 by volume and leave it for 15 minutes, and to damaged hair, apply a mixture of complex protein: perm agent = 2: 8 by volume. Leave it for about 15 minutes, and apply the mixture mixed in a volume ratio of complex protein:perm = 3:7 to extremely damaged hair and leave it for about 10 minutes.

c) applying the liquid protein

Step c) is a process of additionally supplying protein to the hair to which the perm agent and protein have been applied.

The liquid protein is the same as the liquid protein of step a).

In the process of applying the liquid protein, it may be left naturally for 5 to 30 minutes after applying the liquid protein to the hair so that the protein is sufficiently absorbed into the hair.

d) applying electrolytic reduced water

Step d) is a process of improving protein retention by forming a hydrophobic film on the surface of the hair using electrolytic reduced water.

Electrolytic reduced water can be obtained by electrolysis of water composed of hydrogen and oxygen. When water electrolysis the limited movement of the ions by the electrolytic diaphragm in the positive (+) OH ^-, and the number becomes oxidized O ₂ occurs, but the movement of the cathode bound H ⁺ is increased to obtain the number of the cation, the cathode ( In -), the ^{movement of H +} is restricted and OH ^- is increased to obtain anionic water. The electrolytic reduced water has a smaller size than water molecules, so it is easily absorbed by the hair, and at this time, the protein component is also absorbed, thereby increasing the absorption of the protein. At this time, when cationic water is used as the electrolytic reduction water, the protein in the swollen hair can be settled by adjusting the pH of the hair to be weakly acidic. When using anionic water, the anion uses the ionic bond of the hair to form a hydrophobic film on the hair surface. It is possible to give hydrophobicity back to damaged hair and prevent protein leakage from the inside of the hair.

In addition, the electrolytically reduced water may be used together with the protein components constituting the hair. The protein that can be used herein may be keratin protein, collagen protein, silk protein, etc. similar to hair components, and additives such as surfactants, moisturizers, silicone polymers, pH adjusters, thickeners, oils, fragrances, pigments, and preservatives known in the art. can be further used. The electrolytic reduced water mixture in which the electrolytic reduced water and the protein are mixed has weak acidity, and it is possible to prevent protein leakage from the swollen hair by supplying protein to the hair.

In the process of applying the electrolytic reduced water, the electrolytic reduced water can be evenly sprayed on the hair and then left naturally for 5 to 30 minutes.

e) washing and drying the hair

Step e) is a process of removing the perm, protein, and electrolytic reduced water applied to the hair.

In the hair washing process, rinse the hair with lukewarm water so that there is no residue. At this time, a weakly acidic shampoo can be used to cleanly remove the perm and protein from the hair without losing the pigment and protein inside the hair.

In the drying process of hair, when wet hair is dried with hot wind, the hair may be over-swelled and the outflow of protein from the hair may be accelerated. Therefore, the hair may be dried alternately with a cold wind and a hot wind. For example, if wet hair is dried with a cold wind at the beginning, dried in a mixture of hot and cold air in the middle, and then dried with a cold wind for 5 minutes as a finish, the physical shape of the hair can be contracted and hardened.

f) applying the complex protein

Step f) is a process of additionally supplying protein to the hair.

The complex protein is the same as the complex protein of step b).

In the process of applying the complex protein, it can be left naturally for 5 to 30 minutes after applying the complex protein to the hair so that the protein is sufficiently absorbed into the hair. This complex protein treatment can prevent protein loss and hair damage due to heat during perm in a later step.

g) applying a perm to the hair

Step g) is a process of designing the shape of the hair by perming the hair.

The perm procedure may be a wave permanent or a straight permanent, and in the case of a wave perm, the hair is wound on a rod and left to natural or by applying heat to form a wave, and in the case of a straight perm, the hair is made using a straightener It may be to straighten the

The process of the perm treatment can be performed by applying heat, and the heat temperature can be adjusted according to the condition of the hair, and the wave perm is performed at 80 to 160℃ or the straight perm is performed at 150 to 150°C so that the desired design can be obtained while reducing hair damage. It can be operated at 250℃. For example, in order to prevent moisture evaporation during wave perm treatment, the hair is wrapped in a rod, covered with a non-woven fabric, and heat-treated at 80°C for 10 minutes and at 90°C for 7 minutes, and the non-woven fabric is removed and heat treated at 90-100°C for 10 minutes can do.

h) applying a mixture of neutralizing agent and complex protein to neutralize the hair;

Step h) is a process of fixing the shape of the perm-treated hair while reducing damage to the hair using the complex protein.

The neutralizing agent recombines the cystine inside the hair cut by the perm agent to form a disulfide bond, so that the shape of the hair is permanently maintained. Neutralizing agents are largely divided into hydrobromic acid-based neutralizing agents and hydrogen peroxide-based neutralizing agents. In the case of hydrobromic acid, the neutral pH of 5.0 to 7.5 and the oxidation reaction occur actively, and in the case of hydrogen peroxide, it is acidic with a pH of 2.5 to 3.5. Oxidation reaction occurs actively. Therefore, a neutralizing agent can be selected and used according to the condition of the hair, and it is preferable to use a hydrogen peroxide-based neutralizing agent that is easy to chemically decompose and has strong oxidizing power.

The complex protein is the same as the complex protein of step b).

The application process of the mixture of the neutralizing agent and the complex protein can be processed by adjusting the mixing ratio and leaving time according to the condition of the hair. For example, to healthy hair, apply a mixture of complex protein: neutralizer = 1: 9 by volume and leave it for 15 minutes, and to damaged hair, apply a mixture of complex protein: neutralizer = 2: 8 by volume. Leave it for about 15 minutes, and apply the mixture mixed in a volume ratio of complex protein: neutralizer = 3: 7 to extremely damaged hair and leave it for about 10 minutes.

i) washing the hair

Step i) is a process of removing the neutralizing agent and protein applied to the hair.

In the hair washing process, rinse the hair with lukewarm water so that there is no residue. In this case, a weakly acidic shampoo may be used to cleanly remove the neutralizing agent and protein from the hair without losing the pigment and protein inside the hair.

In the drying process of hair, when wet hair is dried with hot wind, the hair may be over-swelled and the outflow of protein from the hair may be accelerated. Therefore, the hair may be dried alternately with a cold wind and a hot wind. For example, by drying wet hair with cold wind in the beginning to prevent damage from heat, and drying with hot wind in the middle to reproduce the form of a heat perm made by hydrogen bonding, the hair shape naturally takes place by oxidation with oxygen in the air. After helping the hair, you can return the hair to a stable shape by further drying the swollen hair with heat and water with cold wind.

The perm treatment method according to the present invention can minimize hair damage due to perm by supplying protein to the inside of the hair in stages and forming a hydrophobic film on the surface of the hair using electrolytic reduced water. Various perm treatments are possible due to its excellent fixing power.

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings. However, these descriptions are provided for illustrative purposes only to help the understanding of the present invention, and the scope of the present invention is not limited by these illustrative descriptions.

Example 1. Perm procedure

Perm treatment was performed on female participants with severe hair damage due to frequent dyeing and heat perm (magic).

Although the hair of the participants was thick, the strength and elasticity were greatly reduced due to the loss of internal protein in the hair due to frequent chemical treatments. First, a liquid protein was applied to the hair and the heat of a hair dryer was applied to settle the protein in the hair. The perm agent (Altox Mild product) and the complex protein (see Table 1 below) were mixed in a volume ratio of 7:3 and left for 15 minutes after application. In order to confirm whether or not the hair is reduced, hair strength and reduction tests were performed. As for the reduction test, the degree of reduction was determined according to the condition of the curl by unwinding the hair after winding it on the rod. After applying liquid protein to the hair and filling the empty space inside the swollen hair due to the alkali of the perm agent, a mixture of electrolytic reduced water and protein (pH 4.5) is sprayed on the hair surface to stably shrink the hair and reduce the hydrophobicity. It was made so that water did not penetrate. The hair was washed with a shampoo of pH 4.5, and the wet hair was dried with a cold wind at the beginning using a hair dryer, and dried in a mixture of hot and cold air in the middle, and then dried with cold air for 5 minutes as a finish. Again, the complex protein (see Table 1 below) was applied to the hair. Wrap the hair in a rod and wrap it with a non-woven fabric to heat it at 80 ~ 90°C for 10 minutes, then steam it for 5 minutes. In order to give dry heat, remove the nonwoven fabric and keep it at 90 ~ 100°C for 10 minutes. It was heat-treated. When the moisture in the hair is dry, it is left for about 5 minutes until the heat cools down. Hydrogen peroxide and complex protein (see Table 1 below) were mixed in a volume ratio of 9:1 and applied to hair, and neutralized for 5 to 7 minutes. The hair was washed with a shampoo of pH 4.5 in lukewarm water, dried with a cold wind at the beginning to prevent heat damage, and dried with a hot wind in the middle to help the hair naturally wavy, and then completely dried with a cold wind.

Example 2. Perm procedure

Volume perm was performed on female participants with severe hair loss due to frequent dyeing and discoloration.

The participants' hair was in a state where strength and elasticity were greatly reduced due to the loss of internal protein in the hair due to frequent chemical treatments. First, a liquid protein was applied to the hair and the heat of a hair dryer was applied to settle the protein in the hair. The perm agent (Altox Mild product and Hill Apply product mixed in a volume ratio of 1:1) and complex protein (see Table 1 below) were mixed in a volume ratio of 7:3 and left for 15 minutes after application. The bleached area can have a relatively quick reaction, so apply it thinner than other areas and leave it for the same time. In order to check whether the hair is reduced or not, a hair strength and reduction test was performed. As for the reduction test, the degree of reduction was determined according to the condition of the curl by unwinding the hair after winding it on the rod. After applying liquid protein to the hair and filling the empty space inside the swollen hair due to the alkali of the perm agent, a mixture of electrolytic reduced water and protein (pH 4.5) is sprayed on the hair surface to stably shrink the hair and reduce the hydrophobicity. It was made so that water did not penetrate. The hair was washed with a shampoo of pH 4.5, and the wet hair was dried with a cold wind at the beginning using a hair dryer, and dried in a mixture of hot and cold air in the middle, and then dried with cold air for 5 minutes as a finish. Again, the complex protein (see Table 1 below) was applied to the hair. Wrap the hair in a rod and wrap it with a non-woven fabric to heat it at 80 ~ 90°C for 8 minutes, then steam it for 5 minutes. In order to give dry heat, remove the nonwoven fabric and keep it at 90-100°C for 8 minutes It was heat-treated. When the moisture in the hair is dry, it is left for about 5 minutes until the heat cools down. Hydrogen peroxide and complex protein (see Table 1 below) were mixed in a volume ratio of 9:1 and applied to hair, and neutralized for 5 to 7 minutes. The hair was washed with a shampoo of pH 4.5 in lukewarm water, dried in cold wind at the beginning to prevent heat damage, and in the middle, dried with hot air to help the hair naturally settle into waves, and then dried with cold wind. In addition, an oily protein (heal protein mask product) was applied to the hair so that the protein component was maintained, and then lightly rinsed and dried.

Example 3. Perm procedure

Heat perming was performed on female participants with severe hair damage due to frequent perming and dyeing.

The participant's hair was in a poor condition due to internal damage rather than external damage. First, a liquid protein was applied to the hair and the heat of a hair dryer was applied to settle the protein in the hair. A perm agent for damaged hair (containing cysteamine of pH 7.1) and complex protein (see Table 1 below) were mixed in a volume ratio of 8:2 and left for 15 minutes after application. In order to confirm whether or not the hair is reduced, hair strength and reduction tests were performed. As for the reduction test, the degree of reduction was determined according to the condition of the curl by unwinding the hair after winding it on the rod. After applying liquid protein to the hair and filling the empty space inside the swollen hair due to the alkali of the perm agent, a mixture of electrolytic reduced water and protein (pH 4.5) is sprayed on the hair surface to stably shrink the hair and reduce the hydrophobicity. It was made so that water did not penetrate. The hair was washed with a shampoo of pH 4.5, and the wet hair was dried with a cold wind at the beginning using a hair dryer, and dried in a mixture of hot and cold air in the middle, and then dried with cold air for 5 minutes as a finish. Again, the complex protein (see Table 1 below) was applied to the hair. Wrap the hair in a rod and wrap it with a non-woven fabric to heat it at 80 ~ 90°C for 10 minutes, then steam it for 5 minutes. In order to give dry heat, remove the nonwoven fabric and keep it at 90 ~ 100°C for 10 minutes. It was heat-treated. When the moisture in the hair is dry, it is left for about 5 minutes until the heat cools down. Hydrogen peroxide and complex protein (see Table 1 below) were mixed in a volume ratio of 9:1 and applied to hair, and neutralized for 5 to 7 minutes. The hair was washed with a shampoo of pH 4.5 in lukewarm water, dried with a cold wind at the beginning to prevent heat damage, and dried with a hot wind in the middle to help the natural waves of the hair settle down, and then dried with a cold wind. In addition, an oily protein (heal protein mask product) was applied to the hair so that the protein component was maintained, and then lightly rinsed and dried.
