ABSTRACT:
The present invention relates to a hair dye composition containing a dissociative azo dye which has high dyeing power, is capable of imparting a vivid color to the hair firmly, has excellent fastness to light, shampooing, sweat, friction, and heat, and fades less with the passage of time because the dye is stable against an alkali agent or an oxidizing agent and does not decompose during hair dyeing; and a hair dyeing method using the hair dye composition.
