(57) [Summary] [Problem] There is no change over time, the mixing performance of the first and second agents is good, the operability such as hardly dripping when applied to the hair and no scattering, and the dyeability are further improved. Provide an excellent oxidative hair dye composition. SOLUTION: In the first part of the hair dye composition mixed with a second part containing an oxidizing agent at the time of use, the following components (A) and (B): (A) a carboxyvinyl polymer and / or acrylic acid. Alkyl methacrylate copolymer (B) Acrylamide and 2-acrylamide-2- A hair dye composition comprising a copolymer with methylpropanesulfonic acid. |
