Description

According to the present invention, the hair repair effect is certain, the effect is long-term, the effect of perm and color is sustained, the damage is suppressed, and the hair is gradually restored to healthy hair as the number of times is increased. Regarding promising hair-beautifying agents, hair-beautifying methods, and hair-beautifying devices.

The general physical and chemical properties of human hair are as follows. The main component is keratin protein, the water content per bottle is about 11 to 13%, and the pH is 4.5 to 5.5. In addition, the thickness is 0.05 to 0.1 mm, and one strength can lift a heavy object of 100 to 150 g, and it is strong against acidity (weak against alkalinity), and it takes about 10 minutes in an environment of 110 ° C., 180. In an environment of ° C, it becomes brittle in about 10 seconds.

Hair is composed of a central medulla, a cortex that surrounds the medulla, and a cuticle that surrounds the cortex and covers the surface of the hair.

In addition, corticus is composed of corticus cells, in which about 60% are macrofibrils that form hair consisting of proteins such as melanin, which determines hair color, and hard fibrous keratin. It is composed of a substance called.

Hair is formed by connecting the above macrofibrils with each other (matrix protein) and filling the gap (non-keratin protein) with a "filling substance" of matrix protein and non-keratin protein to surround the medura. There is.

The filling substance has the effect of moisturizing the hair, trapping water, and giving the hair elasticity, suppleness, and firmness, and is softer and smoother than macrofibrils containing keratin (which constitutes corticus cells), which is hard and fibrous. There are various physical properties.

In addition, the filling substance has the property of being easily affected by "drugs" such as perms and coloring in hair and easily reacting, and by utilizing this property, for example, it is directly affected by the action of a perm drug. The hair is dyed by moving it to perm it, for example, by taking in a coloring agent and trapping the dye inside.

On the other hand, since the filling substance is not (soft) crystallized, that is, it is not stable, it is easily washed away without using the above-mentioned chemicals, and when the filling substance is reduced or lost, the suppleness of the hair is lost. In addition to losing moisture, firmness, and elasticity, it becomes dry, stiff, and difficult to organize, and contrary to the above, it is difficult to apply perm, and even if you color it, it is difficult to dye your hair or the dyed color is easy to fade. It will be easier. That is, most of the so-called "hair damage" phenomena are caused by the decrease or loss of filling substances.

As mentioned above, the filling substance flows out due to dryness, ultraviolet rays, wrong hair care, etc., even if it is not based on a drug. The cuticle is layered around the cortex, which is composed of a filling substance, in 5 to 6 layers from the hair root to the tip like a bamboo shoot skin to protect the cortex from external impact and irritation. ing.

Therefore, the cuticle may be peeled off by the influence of chemicals such as perm solution or coloring agent, destroyed by exposure to ultraviolet rays, forcibly brushed with the hair entangled, or damaged by frequent brushing. To do. While the cuticle protects the cortices, the outflow of interstitial material can be prevented, but of course, when the cuticle is peeled off, the interstitial material will flow out. In addition, cutting the hair exposes the corticus and medula, resulting in the outflow of interstitial substances.

Furthermore, the cortics are exposed due to the peeling or breakage of the cuticle, and not only the filling substance flows out, but also due to the above-mentioned physical properties of the hair, hot air is continuously applied for a relatively long time, and a hair iron is frequently used. As a result, the heat denatures the (hard fibrous) keratin in the corticus cells, coagulates the interstitial substance, and loses moisture and firmness.

Conventionally, so-called rinses and treatments (hereinafter collectively referred to as treatment agents) have been used for hair care. Since the main purpose of so-called shampoo is to remove stains including human oil and fat components, it is not used as a hair care material here.

The composition of the treatment agent is generally defined as a higher alcohol component, a softening component, a silicone-based component, and a repair component. The higher alcohol is blended to reduce the fluidity so that it does not immediately run off the hair and to replenish the fat and oil components. Specifically, for example, stearyl alcohol, cetearyl alcohol, and cetanol are used.

The softening ingredient is blended to prevent static electricity generated in the hair (prevention of negative polarization) and to suppress the repulsion between static electricity charged in the hair to improve so-called combing (finger passage) and cohesion. Cationic surfactants such as behentrimonium chloride and stealtrimonium chloride are used.

Silicone-based ingredients are simply coated to coat the cuticle (surface layer of hair) to improve the feel (slip), give gloss, and suppress the squeaky feeling after shampoo. Specifically, amodimethicone. Dimethicone and cyclopentasiloxane are used.

The repair component is considered to be the most important component in which the characteristics of various treatment agents appear depending on the following objects to be repaired. Repair is to make up for lost or deficient components in the filling material, to improve the properties of the scalp, perm and color, assuming that the cuticle is peeled off and the cortices are exposed. It means to maintain the state of. It is not that there are no treatment agents for all of the following repairs, but the repair effect should be improved by narrowing down the repair targets to one of them and increasing the concentration of specific ingredients. I have to.

The specific components used for repair are as follows, for example.
・ Cortex protein supplementation (improving the texture of firmness and elasticity)
Hydrolyzed keratin, hydrolyzed silk, pericea, hematin, creatine ・ Replenishment of water content of interstitial substances (improvement of dryness)
1,3-butylene glycol, glycerin, Lipidure, hyaluronic acid, honey

・ Replenishing water in Cortics (improving dryness and curly hair)
Hydrolyzed hyaluronic acid, pericea, hydrolyzed collagen / filling material oil supplement (improvement of gloss / flexibility)
Jojoba seed oil, camellia oil, olive oil, meadowfoam oil, ceramide

・ Improve the properties of the scalp (improve the hair growth environment)
Glycyrrhizinate 2K, Swertia japonica extract, clove extract, arginine perm and color maintenance (remove residual chemicals and maintain effect)
Hematin

In addition, as the above-mentioned repair component, for example, as in Patent Documents 1 and 2, "seaweed extract" containing a large amount of amino acids and minerals for the purpose of moisturizing effect and cuticle protection effect and having less influence on human skin etc. than compounds. It is known that it may be used.

According to Patent Document 1 (Japanese Unexamined Patent Publication No. 2010-248115), a hair cosmetic for the purpose of satisfying a glossy feeling and a cohesive feeling can be obtained by blending a red algae extract and triglyceryl. It is disclosed that the blending amount of the algae extract is 0.001 to 0.2% by weight based on the total amount.

Patent Document 2 (Japanese Unexamined Patent Publication No. 2010-248121) describes this problem with the problem that if the hair surface layer is coated with silicon or the like to temporarily conceal the damage, further damage will be caused by long-term use. To solve the problem, a hair protectant consisting of an extract extracted from brown algae using a solvent containing a lower alcohol such as methanol and ethanol is disclosed.

Further, in Patent Document 2, as a mode of use (Example) of the hair protective agent, a powdered brown algae extract (extract) extracted from brown algae with a lower alcohol is dissolved in purified water, and the brown algae extract is used as a whole 3 The hair protectant A is made to be 0.0% by weight, and the filtrate of 1.2% by weight of fucoidan obtained from the residue generated in the extraction process of the brown algae extract is used as the hair protectant B. Further, it is disclosed that these are further diluted and used.

However, using the seaweed extract as a treatment agent has the following problems. That is, among various naturally-derived components and compound components contained in the treatment agent, the compatibility with the cationic surfactant is poor, and if an excess amount with respect to the cationic surfactant is simultaneously mixed, aggregation or precipitation occurs before use on hair. There is a problem that such a chemical reaction occurs, and it is not possible to mix a concentration that can sufficiently exert the effect of the seaweed extract.

From this point of view, Patent Document 1 describes that cationic compounds (cationic sea surface activators) may be appropriately blended together with the red algae extract, but in Patent Document 1, the blending amount of the red algae extract is hair. Since it is an extremely small amount of 0.001 to 0.2% by mass as a percentage of the total cosmetics, the above-mentioned aggregation does not occur. In other words, because of its low concentration, the effect of repairing hair damage caused by the seaweed extract cannot be fully exerted.

On the other hand, Patent Document 2 discloses an example in which the hair protective agent A or the hair protective agent B is directly used as a so-called first liquid or second liquid of a straight perm, a wave perm, or a color. Due to the compatibility with the compound drug solution, it can be inferred that the amount must be small in consideration of the possibility of a reaction accompanied by changes in physical properties.

In other words, although it has been conventionally recognized that seaweed extract surpasses the effects of naturally-derived components and compounds that are generally used as components of treatment agents, it is incompatible with cationic surfactants and only in trace amounts. It could not be blended, and as a result, despite the fact that it contained seaweed extract, it did not function sufficiently as a repair component due to the small amount.

JP-A-2010-248115 JP-A-2010-248121

The problem to be solved by the present invention is that although the seaweed extract is generally used as a component of a treatment agent, it is incompatible with a cationic surfactant and can be blended only in a small amount, resulting in seaweed. Despite the fact that it contains an extract, it did not function sufficiently as a repair ingredient due to the small amount.

In order to solve the above problems, the hair beauty agent of the present invention contains purified water, a base agent containing only anionic components, that is, anionic components, and 5 to 20% by weight of seaweed extract. The main feature was to become.

According to the present invention, by composing the base agent only with anionic components, it is possible to blend the seaweed extract at a high concentration of 5 to 20% by weight, and as a result, the hair repair effect is reliable and moreover. The hair-beautifying effect of seaweed extract is that the effect lasts for a long time, the effect of perm and color lasts, the damage is suppressed, and it can be expected to gradually return to healthy hair as the number of times increases. Can be sufficiently obtained.

It is a figure which shows the schematic structure of the hair-beautifying device of this invention. It is a figure which shows the use situation of the hair-beautifying apparatus of this invention. It is a partial vertical sectional view which shows the other structure of the hair-beautifying apparatus of this invention. It is a figure which shows the use situation of the hair-beautifying apparatus of another structure of this invention. It is a figure which shows the other structure of the hair contact part of the hair-beautifying device of this invention. It is a figure which shows the other structure of the hair contact part of the hair-beautifying device of this invention. It is a figure which shows the other structure of the hair contact part of the hair-beautifying device of this invention.

In the present invention, the seaweed extract is incompatible with the cationic surfactant and can be blended only in a trace amount, and despite the fact that the seaweed extract is blended, the trace amount makes it sufficiently function as a repair component. The problem that there was no such problem was solved by blending purified water, a base agent containing only anionic components, and 5 to 20% by weight of seaweed extract.

Cationic (cationic) surfactants have softening, antistatic, and bactericidal effects on hair, and are considered to be almost essential materials for treatments, conditioners, and hair softeners, but these days, they exhibit the above-mentioned bactericidal effects. It is regarded as a problem that irritation damages the skin of hair, and it does not contain amphoteric (amphoteric) surfactants instead of so-called cationic surfactants or cationic surfactants called non-cations. There are also treatments.

Neither treatments using anfo surfactants nor treatments called non-cations that do not contain cationic surfactants can obtain the same softening effect as cationic surfactants, and thus get caught in hair kissing. Since the feel (bad finger passage) is noticeable, it is necessary to take measures such as blending silicon. Although the addition of silicone improves finger passage, it is a sensory effect on the surface of the hair, repairing the medula (medullary) of hair from which the cuticle has peeled off and the interstitial substance has flowed out due to the exposure of cortices. At the same time, the repair component cannot be penetrated toward the medura.

In addition, there are treatments that use anho surfactants and treatments that do not contain cationic surfactants and are called non-cations that do not contain silicone, etc., but basically, abundant fats and oils should be added. Since it only replaces the function of silicon, even if the filling material can be infiltrated toward the medula in the cortex, the cuticle has not been repaired, so it can be washed away immediately again. Filling materials and silicon substitute components will flow down.

In view of the above, the present inventors have conducted various diligent studies, and by applying a high concentration of seaweed extract, which has been blended up to now, to hair, replenishment of interstitial substances and damage to cortics. Of course, it is possible to effectively repair the cuticle that has received it (compared to a small amount of formulation), and it is worth noting that the effect is long-lasting, the effect of perm and color is sustained, and damage is suppressed. It was clarified that the hair gradually returns to healthy hair with each use due to the virtuous cycle.

However, when only the seaweed extract was applied to the hair, it was difficult to handle because the seaweed extract itself was too viscous and could not be applied well. Therefore, the content ratio of the seaweed extract in the commercially available treatment was increased. However, as in the prior art, when other ingredients, especially cationic ingredients, are mixed, only a small amount can be mixed, and if you try to mix more than this, a reaction with other ingredients will occur and the hair will be mixed. It turned out that the above positive effect could not be obtained.

Through the above process, the present invention enhances the function (effect) of the seaweed extract by blending a large amount of the seaweed extract, making the large amount of the seaweed extract easy to handle, and making it easy to handle, thereby obtaining a favorable effect. The above configuration was used to obtain a hair-beautifying agent that can be used.

In the present invention, by using a base agent containing only anionic components, the base agent and the seaweed extract do not react with each other to cause aggregation, and therefore, compared with the conventional compounding amount of 5 to 20% by weight, 10 It has become possible to mix as much as 100 times as much as possible.

If the amount of the seaweed extract is less than 5% by weight, the effect of the large amount of the seaweed extract cannot be sufficiently exerted, and the amount of the seaweed extract higher than 20% by weight is possible, but it exceeds 20% by weight. It may be difficult to handle, such as being sticky and difficult to apply to hair.

Further, in the above composition, if the hair beauty agent of the present invention uses an extract of sugar beet as a base agent, the entire hair can be composed of naturally derived components in which no chemical component is present. Therefore, when the hair beauty agent contains a chemical component. Compared with this, it is less irritating to hair and head cover, has a high affinity for hair, and the effect of sugar beet extract is further enhanced.

Further, in the above-mentioned composition, the hair beautifying agent of the present invention may contain any or a plurality of sodium hyaluronate, glycerin, raffinose, and betaine as the main component. These are all anionic components and components that can be extracted from sugar beet.

"Sodium hyaluronate" is easily dissolved in water, easily blends into hair and skin, and has a moisturizing effect.
"Glycerin" has a moisturizing effect and a softening effect, and since it is a skin component in the first place, it also has a skin conditioning effect.

"Raffinose" retains the absorbed water and has the property of not having hygroscopicity, and also has the effect of correcting the lamellar structure in which lipids and water are laminated in a sandwich shape, and imparts a hair barrier function. It will be.
"Betaine" is a double-sided surfactant having cations and anions, but it is not necessary for the surfactant effect in the present invention, and mainly has a (non-excessive) cleaning effect, moisture absorption and moisturization, and water retention. , Formulated for the purpose of antistatic effect.

By doing so, it is possible to individually repair the hair damage factors without impairing the effect of the large amount of seaweed extract.

Further, in the present invention, the seaweed extract may be extracted from brown algae or red algae in the above configuration. Seaweeds include seaweed, kelp, hijiki, hiba mata, sargassum, mozuku, trumpet, wakame seaweed "brown algae", asakusanori, gelidiaceae "red algae", osa, aonori, acetabularia ryu, cactus, and seaweed. It is roughly divided into.

The extracts extracted from these seaweeds are a group of water-soluble low-molecular-weight compounds that refer to low-molecular-weight nitrogen compounds, monosaccharides / oligosaccharides, organic acids, minerals, etc., and highly water-soluble compounds that include water-soluble proteins and polysaccharides. It means all soluble components with a group of molecular compounds.

Since amino acids and proteins are particularly required as hair repair components, seaweeds extracted by a method of extracting water-soluble polymer compounds from brown algae and red algae, which are rich in these components and have thickening polysaccharides. By adopting the extract, the hair repair effect is improved.

In addition, the hair damage repair method using the hair beauty agent of the present invention is performed by applying the hair to the hair, applying heat to the hair for a predetermined time in this state, and washing the hair to ensure the effect of the seaweed extract. It is demonstrated in.

The hair beautifying agent of the present invention has a viscous feel when applied to hair, but when heat is applied after application, water volatilizes and the sugar concentration increases, so the viscosity increases rapidly. , It feels even more sticky. At this time, it surely adheres to the hair and the repair component easily penetrates into the hair.

Then, the applied hair-beautifying agent of the present invention becomes less fluid as described above when heat is applied, while the hair also becomes hot. In general, applying heat to hair is a factor of damage, but damage means that holes through which interstitial substances flow out are created or widened, so the fluidity is now low and the hair is in close contact with the hair. In the hair beautifying agent of the present invention, when the hair is heated, the seaweed extract permeates and is absorbed from the pores through which the filling substance is about to flow out. After that, by rinsing the hair, the excess seaweed extract on the surface layer will flow down, but the established seaweed extract will not flow out just by rinsing because the cuticle is repaired along with the replenishment of the filling substance. ..

Further, in the hair damage repair method using the hair beautifying agent of the present invention, the step of applying negative ions to the hair may be added after applying the hair beautifying agent of the present invention to the hair. By doing so, the pores leading to the inside of the corticus expand more reliably in synergy with the heat application, and the seaweed extract can be easily permeated (fixed) into the corticus.

Further, in the hair damage repair method using the hair beautifying agent of the present invention, a step of imparting positive ions to the hair may be added after the hair has been washed away. By doing this, the established seaweed extract can be trapped in the corticus.

Further, in the hair damage repair method using the hair beauty agent of the present invention described above, the ion-imparting device used for imparting negative ions and positive ions is brought into contact with the hair and used as a positive or negative electrode. The hair contact portion, the body contact portion in which the hair contact portion is brought into contact with the body of the person who has come into contact with the hair, and the electrode has the opposite polarity to the electrode of the hair contact portion, and these hair contact portions and the body contact portion The configuration may be such that the hair is electrically connected via a DC power supply to control the current, and the hair is controlled.

According to the above configuration, applying a voltage to the hair promotes the opening or closing of the cuticle forming the surface of the hair, promotes the penetration of the hair beautifying agent of the present invention into the hair, or penetrates the hair. The hair beauty agent of the present invention can be reliably retained.

Further, according to the present invention, in the above-mentioned ion imparting device, the control unit may be configured to switch the polarity of the hair contact portion by switching the current direction of the DC power supply.

Further, in the above ion imparting device, the control unit may switch the polarity of the hair contact portion by switching according to the voltage frequency of the DC power supply.

By doing so, the present invention can arbitrarily use and properly use only negative ions, only positive ions, or both, and especially when a configuration for switching according to the voltage frequency is adopted, the hair It can stimulate and moisturize the hair.

Further, according to the present invention, in the above configuration, if the hair contact portion is in the form of a comb, a brush, or a structure in which the hair is sandwiched between a pair of spatula, after applying the hair beauty agent of the present invention, or for hair beauty. After rinsing the agent, it becomes possible to appropriately and surely apply ions by using the hair contact portion according to the hair condition.

Hereinafter, specific examples of the present invention and various experiments conducted to confirm the effects will be described with reference to the drawings. First, the configuration and operation of the hair-beautifying device used in the hair-beautifying method of the present invention using the hair-beautifying agent of the present invention will be described with reference to FIGS. 1 to 7.

As shown in FIG. 1, the hair beautifying device 1 is for imparting negative ions, positive ions, or both ions to the hair in the hair beautifying method of the present invention using the hair beautifying agent of the present invention. The main body 2 has a hair contact portion 3 that is in contact with the hair and serves as a positive or negative electrode, and a body contact portion that is in contact with the body of the person to be treated and serves as an electrode opposite to the electrode in the hair contact portion 3. It has a DC power source 5 electrically connected to the hair contact portion 3 and the body contact portion 4, and a control unit 6 for controlling current and voltage.

Specifically, in this embodiment, the main body 2 has a columnar handle portion 2A having a certain length formed from an electrically insulating material such as a synthetic resin, and the handle portion from the tip portion of the handle portion 2A. The hair contact portion 3 is projected in the length direction of 2A.

Then, in the present embodiment, the hair contact portion 3 has a plurality of comb teeth having a constant length on the outer peripheral surface of the rod-shaped substrate 3a having a constant length at small intervals in the length direction of the substrate 3A. It is formed by projecting 3b in the same direction. The comb teeth 3b are configured such that at least the surface thereof is formed of a conductive material such as metal to serve as a positive or negative electrode.

Further, the body contact portion 4 is formed separately from the main body 2, and is formed of a columnar body having a certain length whose surface is at least formed of a conductive material such as metal, and is a comb of the hair contact portion 3. It is configured to be an electrode opposite to the tooth 3b.

The main body 2 and the DC power supply 5 are electrically connected by the lead wire 6, and the body contact portion 4 and the DC power supply 5 are electrically connected by the lead wire 7, so that the hair contact portion 3 in the main body 2 is electrically connected. Each of the comb teeth 3b and the body contact portion 4 are electrically connected via the DC power supply 5.

Further, the DC power supply 5 has a control unit 8 and is provided with a current switch 5A for switching the flow direction of the DC current. By operating the current switch 5A, the control unit 8 switches between a mode in which the direct current flow direction is constantly maintained in a constant direction and a mode in which the direct current flow direction is continuously inverted at a predetermined frequency. ..

Further, the DC power supply 5 is provided with an output switch 32, and the control unit 8 arbitrarily adjusts the voltage (V) between the comb teeth 3b of the main body 2 and the body contact portion 4 by operating the output switch 32. You can do it.

The control unit 8 constantly maintains the comb teeth 3b of the hair contact portion 3 in the main body 2 on the positive electrode or the negative electrode by setting the mode in which the DC current flow direction of the current switch 5A is always maintained in a constant direction. At the same time, the body contact portion 4 is controlled to be constantly maintained at the electrode opposite to the electrode of the comb tooth 3b.

Further, the control unit 8 sets the current switch 5A to a mode in which the flow direction of the direct current is reversed at a predetermined frequency, so that the comb teeth 3b of the hair contact portion 3 in the main body 2 and the body contact portion 4 are separated from each other. In, the positive electrode and the negative electrode are controlled to be inverted at a predetermined frequency. The frequency is adjusted by the control unit 8 by operating the frequency adjustment switch 5C provided on the DC power supply 5.

The operation of the hair beauty device 1 having the above configuration will be described. The operating conditions for implementing the above hair-beautifying method will be described later. Turn on the power of the DC power supply 5 and adjust the current switch 5A so that the DC current always flows from the DC power supply 5 toward the body contact portion 4, that is, the hair contact in the upper body 1. When the comb teeth 3b of the portion 3 are always set to the negative electrode and the body contact portion 4 is always set to the positive electrode, the operation is as follows.

At this time, the voltage (V) between the comb teeth 3b of the main body 2 and the body contact portion 4 is adjusted by the output switch 5B of the DC power supply 5. The voltage (V) between the comb teeth 3b of the main body 2 and the body contact portion 4 is preferably 2 to 30 V, more preferably 12 to 18 V.

Further, the voltage (V) between the comb teeth 3b of the main body 2 and the body contact portion 4 is a predetermined frequency even if it is constant as long as the comb teeth 3b are negative electrodes and the body contact portion 4 is a positive electrode. Although it may be changed, it is more preferable to change it at a predetermined frequency because it is possible to stimulate the hair and give moisture to the hair by changing the voltage (V).

The frequency when the voltage (V) between the comb teeth 3b of the main body 3 and the body contact portion 4 is changed by a predetermined frequency is preferably 0.1 to 100 Hz, more preferably 6 to 12 Hz.

As shown in FIG. 2, the body contact portion 4 of the hairdressing device 1 is gripped by the person P who processes the hair, while the gripping portion 2A of the main body 2 of the hairdressing device 1 is held by, for example, an operator C (for example, an operator C). A hairdresser or the like) grasps and, for example, combs the hair H coated with the hair beauty agent of the present invention with the comb teeth 3b of the main body 2. The person who holds the main body 2 may be the person P who processes the hair.

Then, the direct current generated from the direct current power source 5 returns to the direct current power source 5 from the body contact portion 4 in this example of the hair beauty device 1 through the body and hair through the comb teeth 3b of the main body 2. In this state, a negative voltage is applied to the comb teeth 3b of the main body 2, a negative voltage is applied to the hair H in contact with the comb teeth 3b, the hair H is swollen and softened, and the hair H is swelled and softened. The cuticle forming the surface of the hair spreads.

By combing the hair H with the comb teeth 3b of the main body 2 as a negative electrode, the cuticle of each hair H is surely opened, and the penetration of the hair beauty agent of the present invention into the hair H is promoted. Can be done.

On the other hand, after turning on the power of the DC power supply 5 for the hair beauty device 1, the current switch 5A of the DC power supply 5 is adjusted so that the DC current always flows from the DC power supply 5 toward the comb teeth 3b of the main body 2. That is, when the comb teeth 3b of the hair contact portion 3 in the main body 2 are always set to be positive electrodes and the body contact portion 4 is always set to be negative electrodes, the operation is as follows.

At this time, the voltage (V) between the comb teeth 3b of the main body 2 and the body contact portion 4 is adjusted by the output switch 5B of the DC power supply 5. The voltage (V) between the comb teeth 3b of the main body 2 and the body contact portion 4 is preferably 2 to 30 V, more preferably 12 to 18 V.

The voltage (V) between the comb tooth 3b of the main body 2 and the body contact portion 4 fluctuates at a predetermined frequency even if it is constant as long as the comb tooth 3b is a positive electrode and the body contact portion 4 is a negative electrode. However, it is preferable to fluctuate the voltage (V) at a predetermined frequency because the hair can be stimulated and the hair can be moisturized by fluctuating the voltage (V).

The frequency when the voltage (V) between the comb teeth 3b of the main body 2 and the body contact portion 4 is changed by a predetermined frequency is preferably 0.1 to 100 Hz, more preferably 6 to 12 Hz.

As shown in FIG. 2, the body contact portion 4 of the hair beauty device 1 is gripped by the person P who processes the hair, while the grip portion 2A of the main body 2 of the hair beauty device 1 is gripped by, for example, the operator C. Then, the hair beauty agent of the present invention is applied, and the hair H in a state of being washed away after a lapse of a predetermined time is combed with the comb teeth 3b of the main body 2. The person who grips and operates the main body 2 may be the person P who processes the hair.

Then, the direct current generated from the direct current power source 5 returns to the direct current power source 5 from the comb teeth 3b of the main body 2 in the hair beauty device 1 through the hair H and the body through the body contact portion 4 of the hair beauty device 1. In this state, a positive voltage is applied to the comb teeth 3b of the main body 2, a positive voltage is applied to the hair in contact with the comb teeth 3b, the hair H is tightened, and the surface of the hair H is touched. The forming cuticle closes.

Further, the hair beauty device 1 of the present invention can be used by setting the current switch 5A of the DC power supply 5 to a mode in which the flow direction of the DC current is continuously inverted at a predetermined frequency.

By setting the current switch 5A to the above mode, the positive electrode and the negative electrode can be inverted at a predetermined frequency between the comb teeth 3b of the hair contact portion 3 and the body contact portion 4 in the main body 2. it can.

The frequency is adjusted by the frequency adjustment switch 5C of the DC power supply 5, and is preferably 0.1 to 100 Hz, more preferably 6 to 12 Hz. Further, the voltage (V) between the comb teeth 3b of the main body 1 and the body contact portion 4 is adjusted by the output switch 5B of the DC power supply 5. At this time, the voltage (V) between the comb teeth 3b of the main body 2 and the body contact portion 4 is preferably 2 to 30 V, more preferably 12 to 18 V.

After that, in the same manner as described above, the body contact portion 4 of the hair beauty device 1 is made to be gripped by the person P to be treated, while the grip portion 2A of the main body 2 of the hair beauty device 1 is held by, for example, the operator C. Grips and combs the hair H coated with the hair beauty agent of the present invention with the comb teeth 3b of the main body 2. The person who grips and operates the main body 2 may be the person P who processes the hair.

Then, the positive voltage and the negative voltage are inverted and applied to the comb teeth 3b of the main body 2 in contact with the hair H at a predetermined frequency, and the hair in contact with the comb teeth 3b has a positive voltage and a negative voltage. Are alternately applied at predetermined frequencies.

Then, when a negative voltage is applied to the hair, as described above, the hair H swells and softens, the cuticle surely expands, the penetration of the hair beauty agent of the present invention is promoted, and the positive voltage is applied. When applied to the hair, the hair is tightened and the cuticle on the surface of the hair is closed, so that the treatment agent and the hair growth (hair growth) agent that have penetrated the hair can be reliably maintained in the hair.

At this time, by combing the hair while bringing the comb teeth 3b of the main body 2 into contact with the scalp, positive voltage and negative voltage are alternately applied to the scalp at a predetermined frequency to stimulate the bioelectrolyte in the scalp. Can be massaged to activate blood flow in the scalp.

As described above, when the positive electrode and the negative electrode are inverted at a predetermined frequency between the comb teeth 3b of the hair contact portion 3 and the body contact portion 4 in the main body 2, the process ends. In addition, the current switch 5A of the DC power supply 5 is adjusted so that the comb teeth 3b of the hair contact portion 3 in the main body 2 are always positive electrodes and the body contact portion 4 is always negative electrodes. A positive voltage is applied to the hair that 3b is in contact with to ensure that the cuticles that form the surface of the hair are closed, and that the treatment agent and hair growth (hair growth) agent that have penetrated the hair are surely inside the hair. It is preferable to hold the hair.

It may be configured.

Next, a test conducted to confirm the effect of the hair beauty agent of the present invention will be described. The hair beautifying agent in this example had the following constitution (Example). Brown algae extract weight 14.00% by weight, anionic component sodium hyaluronate extracted from sugar beet 0.06% by weight, glycerin weight 4.00% by weight, raffinose weight 3.00% by weight, betaine weight 3.00 weight %, Purified water weight 75.94%.

In the test, first, the above-mentioned example in which a high concentration of seaweed extract was blended, and collagen (Comparative Example 1) and keratin (Comparative Example 2) were blended in the same amount (14.00% by weight) as in the examples as components replacing seaweed. Comparative Examples 1 and 2 and Comparative Example 3 of a commercially available product described as containing seaweed extract (0.01% by weight) were used.

The test method is to clean the hair with (same) shampoo, wash off the shampoo thoroughly, and apply Examples and Comparative Examples 1 to 3 toward almost the same amount of bundles in the same area of the same subject. , Once dried, then rinsed off Examples and Comparative Examples 1 to 3 to evaluate how much the hair ring was formed at the root, middle and tip of the dried hair and expanded by elasticity. did.

The evaluation is to make a ring of 10 to 12 mm at almost the same place as the root, middle, and tip of the hair, let go, and if the ring is expanded by 10 mm or more, "◎", the ring is 5 mm or more, 10 mm. When the diameter was increased by less than, it was evaluated as "○", when the diameter of the ring was increased by 1 mm or more and less than 5 mm, it was evaluated as "Δ", and when the diameter was hardly increased, it was evaluated as "x". The results are shown in Table 1 below.

From the above results, it was found that by blending the seaweed extract in a high concentration as in this example, a difference in hair elasticity occurs as compared with a commercially available product containing a trace amount. It was also found that even if the same amount of the same component as the seaweed extract was blended, the effect of the seaweed extract was not reached.

Next, an experiment for confirming the effect of the hair-beautifying method of the present invention will be described. In the test, the commercially available products of Examples and Comparative Example 3 were used for hair bundles in the same region of three subjects having almost the same hair quality, hair length, and hair damage, and the above was based on the difference between methods 1 to 8. I saw a difference in the elasticity of the hair.
Method 1: Shampoo → Comparative Example 3 Application → Dry → Flush → Dry → Elasticity test Method 2: Shampoo → Example application → Dry → Pour → Dry → Elasticity test

Method 3: Shampoo → Comparative Example 3 application → Negative ion addition →
Drying → Flushing → Drying → Elasticity test method 4: Shampoo → Example application → Negative ion addition →
Dry → flush → dry → elasticity test

Method 5: Shampoo → Comparative Example 3 Application → Drying → Flushing →
Add positive ions → Dry → Elasticity test method 6: Shampoo → Apply Example → Dry → Pour →
Add positive ions → Dry → Elasticity test

Method 7: Shampoo → Comparative Example 3 application → Negative ion addition →
Drying → Pour → Add positive ions → Dry → Elasticity test method 8: Shampoo → Apply Example → Add negative ions →
Drying → flushing → adding positive ions → drying → elasticity test

Regarding method 1 and method 2, the hair of each of the three subjects was cleaned with (same) shampoo for the entire head area, the shampoo was thoroughly washed off, and all the subjects were put into a bundle of almost the same amount in the same area. Toward the hair, each of Example and Comparative Example 3 was applied and dried once, and then the Example and Comparative Example 3 were washed away and dried at the root, middle and tip of the hair. We evaluated how much the diameter was expanded by the elasticity.

Regarding the method 3 and the method 4, in the above method 1 and the above method 2, the example and the comparative example 3 are applied respectively, and until they are dried once, that is, after the examples and the comparative example 3 are applied respectively, the above figure. Negative ions under the same conditions are applied using the hair beautifying device 1 shown in 1 and FIG. 2, and then a hair ring is formed at the root, middle, and tip of the hair through the same steps as in method 1 and method 2. It was evaluated how much the diameter was expanded by the elasticity.

Regarding the methods 5 and 6, in the above methods 1 and 2, the above FIGS. 1 and 2 show that after the examples and the comparative examples 3 have been washed away and before they are dried, that is, after the examples and the comparative examples 3 have been washed away. Using the hair beauty device 1 shown in 2, positive ions under the same conditions are applied, and then through the same steps as in methods 1 and 2, hair rings are formed at the root, middle, and tip of the hair, and which is elastic. It was evaluated whether the diameter was expanded to some extent.

Regarding method 7 and method 8, after applying Examples and Comparative Examples 3 respectively in the above methods 1 and 2, negative ions under the same conditions are applied using the hair beauty device 1 shown in FIGS. 1 and 2. Then, after drying and washing away Examples and Comparative Examples 3, positive ions under the same conditions were applied using the hair-beautifying device 1 shown in FIGS. 1 and 2 above, and thereafter, the same as in Method 1 and Method 2. Through the process, a ring of hair was formed at the root, middle, and tip of the hair, and the extent to which the diameter was expanded by elasticity was evaluated.

The evaluation is to make a ring of 10 to 12 mm at almost the same place as the root, middle, and tip of the hair, let go, and if the ring is expanded by 10 mm or more, "◎", the ring is 5 mm or more, 10 mm. When the diameter was increased by less than, it was evaluated as "○", when the diameter of the ring was increased by 1 mm or more and less than 5 mm, it was evaluated as "Δ", and when the diameter was hardly increased, it was evaluated as "x". The results are shown in Table 2 below.

From the above test results, it was confirmed that the method 2 using the hair-beautifying agent of this example returned more elasticity than the method 1 using the commercially available product of Comparative Example 3. Further, in the methods 3 and 4 to which the negative ions are applied, since the repair component easily permeates into the cortex by expanding the holes leading to the inside of the cortex, the cases where Examples and Comparative Examples 3 are used are used. In particular, the elasticity from the middle to the tip was increased as compared with Method 1 and Method 2, but Method 4 was more effective than Method 3 in that it also used a high concentration of seaweed extract.

Further, in the methods 5 and 6 in which positive ions are applied, since the holes leading to the inside of the cortex are closed, the repair component that has penetrated into the cortex is less likely to re-flow out, so Examples and Comparative Examples 3 are used. In particular, the elasticity from the middle to the tip was increased as compared with Method 3 and Method 4, but Method 6 was more effective than Method 5 in that it also used a high concentration of seaweed extract.

Further, in the methods 7 and 8 in which the positive ions are added after the negative ions are applied, the holes leading into the cortex are expanded to facilitate the permeation of the repair component into the cortex, and after the permeation, the corte By closing the hole leading to the inside of the ix, the repair component that has penetrated into the corticus is less likely to re-flow out. Therefore, when the examples and comparative examples 3 are used, the elasticity toward the tip is particularly different from that of methods 5 and 6. Compared with Method 7, Method 8 was still more effective in that it used a high concentration of seaweed extract.
