Description

The present invention relates to a hair dyeing method using a three-component hair dye having a high dyeing effect on hair, excellent color sustainability, and little skin dyeing.

Conventionally, oxidation hair dyes and acid hair dyes have been used as general hair coloring agents. Most of the above oxidative hair dyes are of the two-component type, and the first agent contains a dye intermediate such as paraphenylenediamine and an alkali agent, and the second agent contains hydrogen peroxide. It consists of the oxidizing agent used. And by mixing and using the first agent and the second agent, it is a method of decomposing melanin in the hair and simultaneously causing an oxidative polymerization reaction to dye the hair.
It is widely used for gray hair, fashion dyeing and fashion dyeing.

However, in recent years, the use frequency of hair color has increased, and the problem of allergy due to dye intermediates such as paraphenylene diamine used in oxidative hair dyes has been addressed, and further safety efforts are important. It has become to.

On the other hand, an acidic hair dye is a one-component type in which an acidic dye is blended, and is a method of dyeing hair by ion adsorption with hair in an acidic region. In addition, since an acid dye is used without using a dye intermediate, the hair dye can be used more safely with relatively few problems of allergies.

However, the problem with acidic hair dyes is that they are strongly dyed to the skin and scalp and are very difficult to remove once the skin and scalp are dyed. In the treatment in the hairdressing and beauty salon,
Not only is advanced technology necessary for dyeing at the root of the hairline, but it also takes a considerable amount of time and cannot be said to be efficient. In addition, acidic hair dyes have no action of decomposing melanin in the hair, and only keep the acidic dye in the hair, and are generally used for changing the nuances of white hair and hair, It is not used for gray hair or fashion dyeing to make hair look brighter.

As described above, hair coloring agents have not only allergic problems but also problems such as staining on the skin and scalp. To solve this problem, hair coloring products using basic dyes are widely available in the market. Part is seen.
Hair dyes using basic dyes have a problem that they are less dyed to the skin and scalp but have a poor dyeing effect on the hair and inferior color persistence, and various patents have been submitted (patent documents) 1
To 3).

JP 2004-59565 A JP 2005-179225 A Japanese Patent Laying-Open No. 2005-213243

However, when the basic hair dye described in the above-mentioned patent document is compared with the conventional oxidative hair dye or acidic hair dye, the basic hair dye described in the above-mentioned patent document is less dyed to the skin or scalp, Since the dyeing effect is weak and comparable dyeing cannot be obtained, and the color persistence is also weak, it is not sufficient as a hair dye.

The present invention solves the above-mentioned problems of the conventional examples, and uses a three-component hair dye that can be effectively dyed on hair and can be applied with bright lightness. It is to propose a hair dyeing method.

In order to solve the above-mentioned object, the invention according to claim 1 of the present application is that the first agent contains (A) a basic dye and / or an HC dye, and (B) contains or contains a benzyl alcohol.

The basic dye and / or HC dye cause less allergy compared to dye intermediates used in oxidative hair dyes, and less dye to the skin and scalp than acid dyes. It is a dye that can be used more safely.

The content of the basic dye and / or HC dye at the time of mixing the first agent and the second agent is 0
. It is 1-3.0 mass%, Most preferably, it is 0.5-2.0 mass%. 0.1% by mass
If it is less than 3.0%, the dyeing effect is weak, and if it exceeds 3.0% by mass, the dyeing on the hair surface will increase excessively, causing not only the problem of discoloration, but also increasing the blending amount unnecessarily. Is also not economically preferable.

In the hair dyeing method using the three-component hair dye of the present invention, the benzine alcohol used for the first agent and the second agent is blended to promote the penetration of the dye into the hair and enhance the dyeing effect. Yes. Since the first agent and the second agent are used as a mixture, they may be contained in either or both of the first agent and the second agent. The content during mixing of the first agent and the second agent is 1.0 to 7.0 mass%, particularly preferably 3.0 to 5.0 mass%. If the amount is less than 1.0% by mass, a good dyeing effect cannot be obtained.

In the hair dyeing method using the three-component hair dye of the present invention, the pH of the first agent is 4.0 to 7.0, and particularly preferably pH 5.0 to 6.0. When the pH is less than 4.0, when the first agent and the second agent are mixed and applied to the hair immediately before hair dyeing, the pH during mixing becomes lower and the dyeing effect becomes weaker. For long-term storage, the stability of the dye in the first agent is affected, and the dyeing effect becomes weak.

3 mole / 1, particularly preferably 0.1 mole / 1 to 0.2 mole / 1. If it is less than 0.02 mole / 1, a good dyeing effect cannot be obtained. If it exceeds 0.3 mole / 1, a stable state of the basic dye and / or HC dye cannot be obtained, and the dyeing property also deteriorates. Excessive formulation is undesirable because it causes hair damage.

In the hair dyeing method using the three-component hair dye of the present invention, the pH of the second agent is pH 7.5 to 9.0.
The pH is particularly preferably 8.0 to 8.5. If the pH is less than 7.5, the first agent and the second agent are mixed just before the hair dyeing and applied to the hair, so the pH during mixing becomes too low and the dyeing effect is weak. Is not preferred because the degree of swelling rapidly increases and causes hair damage.

In the hair dyeing method using the three-component hair dye of the present invention, specific examples of the oxidizing agent used in the third agent include sodium bromate, potassium bromate, and hydrogen peroxide. And content of this oxidizing agent is 1.0-7.0 mass%, Most preferably, it is 2
. It is 0-5.0 mass%. If the amount is less than 1.0% by mass, sufficient oxidation is not performed, leading to hair damage and poor color persistence. If the amount exceeds 7.0% by mass, the color persistence does not increase any more. It is not preferable because it is not economical.

On the other hand, as a method of dyeing with lightness of the hair, a lightener composed of the first agent and the second agent is mixed, the hair is pretreated, and then a hair dyeing method using a three-component hair dye is used. It is.
The lightner treatment is a colorant that can be used widely from gray hair dyeing to fashion dyeing by decomposing melanin in the hair and increasing the lightness of the hair.
