An object of the present invention is to provide a first agent composition for hair dyeing having excellent formulation stability even when stored for a long time. SOLUTION: In order to solve the above problems, (A) oxidation dye to which sulfuric acid is added, (B) sodium alkyl sulfate having 14 or more carbon atoms, (C) higher alcohol, and (A) component contained The first agent composition for hair coloring, which is characterized in that the amount is 2 to 10% by mass, is provided. Thereby, even if the content of the oxidation dye to which sulfuric acid is added is increased, an effect of being excellent in formulation stability can be obtained. 【Selection chart】 None |
