PROBLEM TO BE SOLVED: To provide an oxidative hair dye composition which has excellent hair dyeing power without generating gas during storage in a container, can obtain a natural hair dyeing state, and can suppress damage to hair. I will provide a. An oxidative hair dye composition contains an oxidative dye and is used by being mixed with an oxidant composition, wherein the component (A) ascorbic acid is added in an amount of 1.0 to 1.0. 8.0 mass% and 0.3-8.0 mass% of components other than carbonate which generate | occur | produces gas with the ammonium salt of component (B) inorganic acid or organic acid are contained. Specifically, ammonium chloride, ammonium acetate, triammonium phosphate and the like are used as the component (B). Further, as component (B), those having a solubility in 100 g of water of 20 g or more at 25 ° C. improve the hair dyeing power, and further precipitate component (B) during storage of the oxidative hair dye composition. It is preferable in preventing. [Selection figure] None |
