Description

Hair Treatment

The present invention relates to a hair treatment method that can cope with various hairstyles.

Traditionally, in order to correspond to the diversification of hairstyles, hair is subjected to a perm treatment to form curls. The above perm treatment is carried out by applying the first agent containing the reducing agent to the hair to form a curl design on the hair, and then applying the second agent containing the oxidizing agent to the hair.

In the first agent, although thioglycolate, cysteine, cysteamine, sodium sulfite, thioglycerol, glyceryl thioglycolate (GMT), butyrolactone thiol (raw material name "Spiera"), etc. However, except for glyceryl thioglycolate and butyrolactone thiol, it cannot exert its effect unless it is alkaline. Because the use of alkaline reducing agents will swell the hair, it will damage the hair even more if it is used on damaged hair. On the other hand, glyceryl thioglycolate and butyrolactone thiol are used in a neutral to acidic state and hardly swell the hair. That is, the damage to hair was significantly smaller than that using an alkaline reducing agent. However, compared with thioglycolic acid, the price of glyceryl thioglycolate or butyrolactone thiol is very expensive. In addition, because the smell is very different from the traditional alkaline reducing agent used, the hair will not swell, making it difficult for technicians to confirm When can the hair be permed, so it may be kept at a respectful distance. When it is alkaline, you can touch the hair strands with your fingers to confirm that the hair has softened, that is, you can confirm that the perm has been completed (this is called "softening check"). Although traditionally known perm methods include cold perm, digital perm, or direct perm with straight hair design, etc., but due to current habits and economic reasons, most of them still use alkaline reducing agents. hair.

The oxidizing agent used in the second dose is known to include bromate (mostly sodium bromate, some use potassium bromate) and hydrogen peroxide (about 1 to 3%).

1. cold perm

In the cold perm, the first dose of the reducing agent as the main ingredient is applied to the hair, wound on a wave curling iron, and mostly left for about 10 to 20 minutes. At this time, if you have hair that is not easy to perm into waves, you can cover it with a heat-preserving PVC cap that accelerates recovery, or heat it with a far-infrared heater or a steamer (this is called "additional volume") ). In addition, the first dose is applied by wetting the hair with water, wrapping it around a corrugated curling stick, and then applying it from the top of the stick using a dropper or the like (this is called "water curling"). Next, rinse off the first agent with warm water (this is called "intermediate rinse"), dry it with a towel from the top of the stick, apply the second agent with an oxidizing agent as the main component, and leave it for about 5 to 15 minutes in most cases. After leaving it for a while, wash off the second agent, improve the feel with a conditioner, etc., and then dry it with a towel or a hair dryer to complete the grooming.

As a method of easily styling hair into waves at home without going to a beauty salon, there is a method of using curling irons (round irons). The greater the amplitude of the wave, the better, and this type of wave shows "heavy". Although the waves created by the curling iron have ridges, it is easy to lose the wave design by washing the hair. This is because the waves formed by the curling irons are formed only by the hydrogen bonds inside the hair like the hair when you get up. Although it is better to perm to form raised waves, it is difficult to make such large waves with cold perm. Especially when dyed hair is applied, the damage caused by the dye (due to the bleaching that follows the dyeing) causes the hair to lose its elasticity. It is almost impossible to form raised waves on such hair, so at present, beauty salons also make waves with a cold perm, and finally the hairdresser combs them into raised waves with a hair dryer. Using digital perm and other heating rods can relieve the shortcomings of cold perm to a certain extent.

2. Perm with heating rod

The heatable curling iron is connected to the curling iron with a galvanic couple by wires, and the heating temperature or heating time can be adjusted by the control panel, which is the so-called digital perm. Since most digital perm systems are used in beauty salons, only the technical methods of digital perm are described here. The general method of use is as follows.

First, apply the first dose of perm to the hair, after the necessary time to restore, rinse off the first dose, then dry it with a towel until it does not drip, and then wind it on the curling rod (called winding). Connect the coiling rod to the power cord and increase the temperature step by step (for example, 70°C for 5 minutes, 90°C for 5 minutes, 110°C for 5 minutes, etc.). In most cases, it is warmed to dry hair to create waves with a lifting effect. If you don't want to produce too strong waves, you can end the heating in the water-containing state. After warming up, remove the hair from the curling iron, hold the hair strands with clips, etc. to prevent the waves from collapsing, and apply the second dose. The reason why the curling rod is removed at this time is that the model of the digital hair iron may cause a short circuit due to excessive moisture in the curling rod. As long as there is no short circuit problem, the second dose can be applied from the top of the reel. After the second dose has taken effect, remove the clip or curling rod, wash with warm water, apply hair care treatment if necessary, dry with a towel or blow dry to complete the combing.

Usually the hair is damaged at the ends first. A perm will be better than healthy hair up to a point, but beyond a point it will be overly damaged and the waves will collapse. When using a digital hair iron to wind the hair from the tip of the hair to the curling rod, the hair tip will be curled at the innermost point at the highest temperature, so the damage will be the greatest. In addition, even in cold perm or digital perm, there is a disadvantage of unnatural design because the hair tip forms waves with the smallest diameter when winding from the tip of the hair. In terms of the directionality of the cuticle formation, many beauticians also think that it is not natural to create waves in the middle of the hair through curling. In order to avoid this situation during cold perm, although there is a method of moving the curling rod from the root direction of the hair and winding it at the same time, but because the digital perm needs to be heated, even if it is wound from the root of the hair, the temperature will become higher and dry, and Makes the hair fall off the iron so that it can't be wrapped around the roots.

Digital perm is superior to cold perm for greater bulge, and for bleaching, etc. Hair that has lost its elasticity can also be given some degree of wavyness. However, the hair can be damaged by repeated digital perms, and often the ends become stiff and dry. In addition, digital perm equipment is mostly expensive, and many beauty salons cannot afford it due to economic factors.

3. Straight ironing

Direct perm technology is the first dose of perm applied to curly hair (cream-like ones are the main mainstream, others are also gel-like and liquid-like), which mainly cuts the disulfide bonds inside the hair and rinses off the first dose After the dose, perform one of the following two steps.

(1) The method of using hair irons for high temperature hair styling (hair iron direct ironing method)

After rinsing off the first agent, dry it with a towel, and dry it with a hair dryer to the extent that your hands will not get water when you touch it. The hair is moderately bundled, and pressed, straightened and trimmed into straight hair with high-temperature hairdressing irons heated to 160 to 200°C. Next, after oxidation treatment (re-bonding of disulfide bonds) of the second agent (cream-like, gel-like, and liquid-like like the first agent), rinsing is carried out to complete combing. The first dose is a reducing agent adjusted to be alkaline (for example, the pH value of thioglycolate or cysteamine adjusted to 8 to 9.5) as the main component to soften the hair, and then it can be used to adjust from acid to neutral The main ingredient is a reducing agent (butyrolactone thiol or glyceryl thioglycolate adjusted to pH 3 to 7) that hardly softens hair.

At present, this direct ironing method is the mainstream. When using an alkaline reducing agent, because the hair expands, if too much water remains in the hair before the perm, the permed part will foam and seriously damage the hair. Even if done properly, compared with perms other than direct perm, alkaline direct perm can be said to be the most damaging technique among perms due to high temperature and physical pressure of curling irons. On the other hand, when using butyrolactone thiol or glyceryl thioglycolate as the main component of the neutral to acidic first agent, the hair hardly swells, so there is no danger like the alkaline first agent. It can present natural beauty (when it is alkaline, because the hair sometimes expands to more than twice the diameter, it is often combed into an unnatural shape like nylon when it is shaped with hair irons).

(2) Method by hair dryer and hair brush (blow straightening technique)

After rinsing off the first agent, dry it with a towel, blow hot air with a hair dryer from the state where a lot of water remains, and brush it into straight hair. Next, oxidation treatment (rebonding of disulfide bonds) is carried out with the second agent having an oxidizing agent (bromate or hydrogen peroxide) as the main component, followed by rinsing and combing to complete. In this technique, since the hair treated with the first dose must be sufficiently softened, a reducing agent (almost thioglycolate, cysteamine or cysteines) adjusted to alkalinity is used. Only a few beauticians perform this technique due to the skill required.

4. Direct ironing and curling ironing technology

Techniques for curling permed hair are known. For example, Patent Documents 1 and 2 disclose the technology of successively performing direct ironing and waveform ironing. In recent years, there has been a request to change the hairstyle of the hair that has been straightened. That is, those who apply waves to the tips of the hair from the middle of the straightened hair are in vogue. However, especially in the case of women, most of the hair has been dyed (bleached). Compared with the hair that has only been dyed, the hair that is directly permed with high temperature and physical pressure will lose a lot of elasticity. It is not easy to create wavy hairstyles on such damaged hair. In terms of wavy hair design, although there are "C curls" that are semi-circular to partially arc-shaped and curled, "J curls" that are straight and only curled at the ends of the hair, and "S curls" that overlap waves like ordinary perm hair And other shapes, but so far, direct ironing and curling ironing techniques can be used to form S rolls, and only digital ironing can be used. Although there is also a method of cold ironing after direct ironing, compared with digital ironing, only weak waves can be obtained. In addition, although there are methods of using curling irons and methods of using hair straighteners, but in many cases, only C curls and J curls can be obtained respectively, and the curl itself cannot be obtained (that is, the curl itself can be obtained). fail). The following explains the traditional technique of creating waves on hair with a straight perm.

(1) The method of applying cold perm to the hair that has been directly permed

Apply Perm Agent 1 to straight-permed hair, mainly from the middle to the wavy part of the root, and curl Wrapped on a rolling rod. Warm at room temperature or with a far-infrared heater, etc., and let stand for a necessary time. Rinse off after letting it sit, and towel-dry with a roll-up stick before applying the second dose. After the treatment of the second agent is completed, the coiling rod is removed, washed with water, and the carding is completed. In this method, only weakly curled (no hump) S rolls can be obtained.

(2) The method of applying digital perm to the hair that has been directly permed

On straight-permed hair, apply the first part of perm mainly from the middle to the wavy part of the hair root, and wrap it around the curling iron. The following is the same as the general digital ironing method, heat as needed, and use the second agent to oxidize with the part that is only for direct ironing, wash and comb. Using this digital perm method, compared to cold perm, although raised waves can be obtained, the curl of these waves is still weaker than that produced by consumers at home with curling irons. In order to achieve the hairstyle desired by the customer, the hairdresser must curl the hair with his fingers while styling it with a hair dryer while combing the hair in the beauty salon. In addition, it is also a disadvantage to have expensive digital ironing equipment.

(3) The method of using black curling irons on straightened hair

Curling irons for black perms are narrow curling irons used in perms for short hair. The narrow part of the iron plate has the advantage of making the hair easier to bend around the edge of the iron. Apply the first agent to the hair that has been straightly ironed, and bend the hair little by little with a black curling iron to form an angle. This technique is mostly performed near the roots of the hair. Once the hair is angled, apply the second dose in the same way as with a normal perm until the trim is complete. Achieve natural C-curls from root to tip when performed by a skilled technician.

(4) The method of using a hair straightener on the hair that has been directly ironed

Apply the first agent to the hair that has been straightened, and while pressing the hair tip with the hair straightener, slightly bend the hand holding the curling iron to pass the hair in the direction of curling inward. After ironing, it is dried and curled on the inside. Then perform the second treatment on the part including the perm, and comb it in the same way as the general perm. After curling with hair irons, a rather strong curl can be formed immediately, but after combing, the curl is slightly J-curly Spend. Perm treatments for curls are often performed at the same temperature as direct iron treatments.

Figure 1 presents hair applied with the drying technique using glyceryl thioglycolate as reducing agent or the curling technique of the present invention.

Figure 2 presents hair applied with the drying technique using thioglycolic acid as reducing agent or the curling technique of the present invention.

Figure 3 presents hair treated under various conditions using glyceryl thioglycolate or thioglycolic acid as a reducing agent.

The present invention is a hair treatment method, which comprises the following steps:

(1) The step of applying the first dose containing the reducing agent to the hair;

(2) A step of rinsing off the first agent from the hair, and applying a wave-forming accelerator to the hair, wherein the wave-forming accelerator contains at least 1 and water and have a pH of 4 to 9;

(3) In the step of smearing the hair with the aforementioned wave formation accelerator to form a wave design;

(4) A step of applying the second agent containing an oxidizing agent to the hair after drying the hair while maintaining the wavy design; and

(5) A step of drying the hair after rinsing the second agent from the hair.

In this case manual, "wave design" or "wave" refers to "C curl" with a half-circle to arc shape that is curly on the left and right, "J curl" with straight hair and curls only at the tip, and general perm hair. Various shapes with curves, such as the "S roll" with overlapping waves. Also, although there is a distinction between those made with quasi-drugs for shaping waves and those made with cosmetic curling agents as "curls", in the specification of this case, no distinction is made between the use of quasi-drugs and cosmetics. Any one of them is called "wave design" or "wave".

The reducing agent contained in the first agent used in step (1) is not particularly limited, and the reducing agent used in general perm can be used, such as thioglycolate, cysteine, cysteamine, sulfur Lactate, sodium sulfite, thioglycerol, glyceryl thioglycolate (GMT), butyrolactone mercaptan (raw material name "Spiera"), etc. Glyceryl thioglycolate or butyrolactone mercaptan is preferred. Compared with acidic reducing agents, when the pH of thioglycolate and butyrolactone thiol is below neutral, basic ammonium thioglycolate or cysteamine, etc., which do not swell hair, the treatment time can be shortened. The reducing agent system can be used individually by 1 type or in mixture of 2 or more types.

In step (1), after the first agent is applied to the hair, the hair can be left to stand in this state, so that the first agent has a sufficient time to act (for example, 10 to 20 minutes).

The wave forming accelerator used in the step (2) contains water and at least one selected from the group consisting of thickeners, moisturizers and lubricants, and has a pH of 6 to 8. The form of the wave forming accelerator is not particularly limited, and the application to the hair may be in the form of gel or foam. When it is in gel form, its viscosity is preferably 400 to 80,000mPa‧s, more preferably 5,000 to 30,000mPa‧s, and 10,000 to 20,000mPa‧s from the viewpoint of operability and moisture retention when applied to hair. s is even better. condensate The viscosity of the glue can be measured at 25°C in accordance with, for example, the Standards for Quasi-drug Raw Materials 2006‧General Test Method 54. Determination of Viscosity, Method 2, Rotational Viscometer. The wave forming accelerator in foam form can be obtained by, for example, foaming a liquid form forming accelerator using a pump type former.

Thickening agent can enumerate: For example, be selected from polyquaternary ammonium salt-10, polyquaternary ammonium salt-16, polyquaternary ammonium salt-24, sodium carboxymethylcellulose, stearoxy hydroxypropyl methylcellulose Hydroxypropyl Cellulose, Hydroxypropyl Cellulose, Hydroxypropyl Methyl Cellulose, Guar Hydroxypropyltrimonium Chloride, Locust Bean Hydroxypropyltrimonium Chloride, Tara Hydroxypropyltrimonium Chloride Propyltrimonium Chloride, Fenugreek Hydroxypropyltrimonium Chloride, Sodium Hyaluronate, Sodium Chondroitin Sulfate, Tamarind Gum, Xanthan Gum, Triglucose, Propylene Glycol Alginate and Carboxylic vinyl polymers etc. The thickener can be used alone or in combination of several kinds.

Humectants such as propylene glycol, dipropylene glycol, 1,3-butanediol, isobutylene glycol, 1,2-pentanediol, 1,2-hexanediol, 2,4-hexanediol, octanediol , glycerin, diglycerin, sodium pyrrolidone carboxylate, and maltitol, or one or more of them.

Lubricants include, for example, glycerol glucoside, polyoxyethylene methyl glucoside, polyoxypropyl methyl glucoside, polyoxyethylene dioleate methyl glucoside, polyethylene glycol, polyoxyethylene Ethyl polyoxypropylene glycol, polyquaternary ammonium salt-51 and polymethacryloxyethyl phosphorylcholine, etc. Lubricants can be used alone or in combination.

The wave forming booster is effective at a pH of 4 to 9, more preferably at a pH of 6 to 8. In order to make pH into the said range, at least 1 sort(s) of pH adjuster can be used. The pH adjuster can be used without particular limitation as long as it is used in general hair treatment agents, and for example, one or more of sodium monohydrogen phosphate, sodium dihydrogen phosphate, and lactic acid can be used. As long as the wave forming booster has a pH of 4 to 9, it can reduce damage to the hair and at the same time enhance the wave design.

Surfactant, pH adjuster (acid, alkali), grease can be formulated in the wave formation accelerator Chemicals, chelating agents, anti-inflammatory agents, lubricants (polysiloxane, etc.), moisturizers (animal and plant extracts, protein hydrolyzates and their derivatives, amino acids, polysaccharides, etc.), pigments, fragrances, etc.

In step (3), there is no particular limitation on the way the hair is formed into a wave design. For example, a hair iron can be used to form a wave design (curling), or by winding the hair on a heated rod that can be heated to form waves (digital hot). Keeping the hair moisturized by applying a wave booster to the hair in step (2) prevents the formation of hydrogen or salt bonds in the hair, which would hinder the wave formation in step (3), which can be confirmed in step (3) Terrain forms waves design.

For curling, you can use a wave iron or a straight iron. Specifically, the hair is wound on the hair iron from the hair root side of the part where the wave design is formed, and the hair iron is passed along the direction of the hair tip, so that the wave design can be formed on the hair. The method of winding the hair on the hair iron may be any method as long as the hair can be pressed. After one time, there is a method of winding both sides once, or a method of winding one side twice. The speed of passing through the hair iron is preferably 0.3 to 20 cm/sec, more preferably 0.5 to 10 cm/sec. When the passing speed is slow, the wave will become stronger, but if it is too slow, the hair will be dry and the wave will tend to be weakened. As long as it is within the above range, the hair can be prevented from drying and can be curled into strong waves. From the viewpoint of the operability of pressing, when performing curling, it is preferable to use a neutral to acidic reducing agent including glyceryl thioglycolate or butyrolactone mercaptan which does not swell the hair as the first agent. By applying the wave booster to the hair in step (2), moderate smoothness can be imparted to the hair, and the pressing operation can be performed effectively.

In the method of the present invention using a wave forming accelerator, the temperature of the permanent wave can be lower than the conventionally used temperature, preferably 70 to 140°C, more preferably 90 to 120°C. For example, 90 to 130°C is required when an acidic reducing agent is used, and 70 to 110°C is required when an alkaline reducing agent is used. so available than Traditionally lower temperatures create curly designs and therefore less damage to the hair. In addition, because of the use of wave promoters, even on hair that has been directly ironed, you can easily form raised waves with a hair iron without using expensive digital ironing equipment. That is, the hair treatment method of the present invention includes a treatment method for straight ironed hair. When performing the treatment technique of direct ironing treatment and wave forming treatment successively, the wave forming accelerator can be applied after the hair is subjected to ordinary direct ironing treatment, and the curling step can be carried out. With the curling ironing technology of the present invention, the wave design equivalent to digital ironing can be easily and reliably formed on the hair that has been directly ironed. In addition, in the curling ironing technique of the present invention, since the root of the hair that cannot be ironed by digital ironing can be ironed into waves, the hair that has been treated by direct ironing can be formed into a design that is not traditionally available.

Even in beauty salons that do not have expensive digital perm equipment, the curling technology of the present invention is a breakthrough technology that can form a wave design comparable to digital perm, and can easily perform partial perm due to easy operation . In addition, along the direction of hair flow, it can give natural waves to hair roots that digital perm cannot achieve. When waving straight hair from the middle of the hair, the boundary line between straight and wavy will become unnatural when winding from the tip of the hair, but the wave formed by winding from the root of the hair can be trimmed naturally . In addition, when winding the hair tip, in the digital perm, the inner hair tip with the highest temperature and the smallest diameter is damaged more, and the diameter increases as the temperature decreases toward the hair root. That is, the diameter of the part that is difficult to be ironed is larger, and the diameter of the hair tip that is easy to be ironed is smaller. Since the curling technology of the present invention creates waves by pressing, it is easy to form the same waves from the root to the tip of the hair. It is considered to be a powerful weapon for beauticians who are interested in design.

When performing digital ironing, because of the use of wave forming accelerators, heat under milder conditions than traditional conditions, for example, heating at 50 to 90°C for 10 to 20 minutes, or heating at 40 to 80°C for 5 to 30 minutes In minutes, it can reduce the damage to the hair and can definitely form the wave design in a short time. It heats the hair directly while keeping the hair moist, but because it can form a strong wave design, it is good.

In the method of the present invention, it is preferable to include the step (3a) of directly soaking the hair with the wave-forming design in water between the step (3) and the aforementioned step (4). Since the step (3a) is included, the hair can be kept moisturized even after the wavy design is formed, the formation of hydrogen bonds and salt bonds in the hair can be prevented until the oxidizing agent treatment of the subsequent step (4) is performed, and the step ( 3) The wave design formed in 3) is fixed more surely. Maintaining the formed wave design can be done by securing the hair, for example, with bobby pins or by wrapping the hair around a wave roller or supporting the hair with hands. When performing digital perm in step (3), you can directly attach the curling rod to the hair and soak it in water, or remove the curling rod. In step (3a), the temperature of the water is preferably 25 to 40°C, more preferably 30 to 35°C, and the soaking time is preferably 5 seconds to 10 minutes, more preferably 5 seconds to 5 minutes, and 1 minute Up to 4 minutes is better. The hair can be soaked in water using a shampoo basin. If it is difficult to soak in water, add water with a dropper or lotus pod to keep it soaked. The wave forming promoter may or may not be rinsed from the hair before soaking the hair in water.

The oxidizing agent contained in the second agent in the step (4) can be an oxidizing agent conventionally used in hair treatment, for example, bromate such as sodium bromate, or hydrogen peroxide. The maintenance system of the wave design in step (4) is the same as that of step (3a), and can be performed by fixing the hair with hair clips or winding the hair on a wave curling rod or supporting the hair with hands. After applying the second dose to the hair, it is better to leave it for a certain period of time in such a way that the oxidant can fully act and fix the wave design.

In step (5), after rinsing the second agent from the hair, a hair conditioning treatment may optionally be applied before drying the hair.

In the first agent and the second agent used in the present invention, surfactants, acid or alkali agents, greases, chelating agents, anti-inflammatory agents, lubricants (polysiloxanes, etc.) ), cross-linking agent, moisturizing agent (animal and plant extracts, protein hydrolyzate and its derivatives, amino acids, polysaccharides, etc.), Colorings, spices, etc.
