The first agent of the hair dye contains, for example, an alkali agent and an oxidation dye, and comprises (A) at least one oil component selected from oils, waxes, hydrocarbons, and ester oils, (B) an amino-modified silicone, (C) A cationic polymer or the like may be contained. Examples of the alkaline agent and components (A) to (C) contained in the first agent include specific examples of the alkaline agent and components (A) to (C) used in the hair bleaching and destaining agent described above. Same as described above. Oxidation dyes are compounds capable of developing color due to oxidative polymerization by an oxidizing agent and are classified into dye intermediates and couplers, and oxidation dyes preferably include dye intermediates and couplers.

Examples of dye intermediates include p-phenylenediamine, toluene-2,5-diamine (p-toluylenediamine), N-phenyl-p-phenylenediamine, 4,4'-diaminodiphenylamine, p-aminophenol, o- aminophenol, p-methylaminophenol, N,N-bis(2-hydroxyethyl)-p-phenylenediamine, 2-hydroxyethyl-p-phenylenediamine, o-chloro-p-phenylenediamine, 4-amino-m -cresol, 2-amino-4-hydroxyethylaminoanisole, 2,4-diaminophenol, 1-hydroxyethyl-4,5-diaminopyrazole and salts thereof. Specific examples of salts include hydrochlorides, sulfates, and the like. Among specific examples of these dye intermediates, only one kind may be contained alone, or two or more kinds may be contained in combination.

Couplers develop color by combining with a dye intermediate. Examples of couplers include resorcinol, 5-amino-o-cresol, m-aminophenol, α-naphthol, 5-(2-hydroxyethylamino)-2-methylphenol, m-phenylenediamine, 2,4-diaminophenoxyethanol. , toluene-3,4-diamine, 2,6-diaminopyridine, diphenylamine, N,N-diethyl-m-aminophenol, phenylmethylpyrazolone, 1,5-dihydroxynaphthalene, and salts thereof. Specific examples of salts include hydrochlorides, sulfates, and the like. Among specific examples of these couplers, one type may be contained alone, or two or more types may be combined and contained. Since the oxidation dye can change the color tone of hair in various ways, it is preferably composed of at least one selected from the above specific examples of the dye intermediate and at least one selected from the above specific examples of the coupler. Configured. As dyes other than the oxidation dyes, the first agent may appropriately contain, for example, oxidation dyes listed in "Standards for Quasi-drug Ingredients" (published in June 2006, Yakuji Nippo Co., Ltd.).

The lower limit of the content of the oxidation dye in the hair dye is appropriately set, but is preferably 0.01% by mass or more, more preferably 0.1% by mass or more, and still more preferably 0.5% by mass or more. . When the content of the oxidation dye is 0.01% by mass or more, the tint can be particularly improved.

The upper limit of the content of the oxidation dye in the hair dye is appropriately set, but is preferably 10% by mass or less, more preferably 7% by mass or less, and even more preferably 5% by mass or less. When the content of the oxidation dye is 10% by mass or less, the solubility in the solubilizer can be improved, particularly when a solubilizer is used.

In addition, the first agent may further contain, if necessary, components other than the components described above, for example, components contained in the first agent of the hair bleaching/dedying agent described above.
(Second agent of three-agent hair dye)
The second agent of the hair dye has, for example, the same composition as the second agent of the hair bleaching and destaining agent described above.

The third agent of the hair dye has, for example, the same composition as the third agent of the hair bleaching and destaining agent described above. Percarbonate improves the oxidizing action and improves the brightness of the hair after hair treatment. And the gray hair hiding property is improved.

<Four agent type hair dye>
A four-component hair dye can be constructed by using a separate component in the first component of the three-component hair dye. For example, a first agent containing an alkaline agent, a second agent having the same composition as the second agent of the three-agent hair dye described above, and a third agent having the same composition as the third agent of the three-agent hair dye. and a fourth agent having a composition obtained by removing the alkaline agent from the first agent of the three-agent type hair dye described above. A four-component hair dye thus constituted has good storage stability. In addition, a first agent having a composition obtained by removing the alkaline agent from the first agent of the three-agent hair dye described above, and a second agent having the same composition as the second agent of the three-agent hair dye described above. , a third agent having the same composition as the third agent of the three-agent hair dye, and a fourth agent containing an oxidizing agent such as persulfate.
