The effect exhibited by the hair dye composition was superior to the conventional hair dye composition. Moreover, even if the hair dye composition contains an oxidation dye in the form of hydrochloride or sulfate, the stability of the agent is good, and the range of dye selection is widened.

  Accordingly, it is an object to be solved to provide a hair dye composition that achieves both good hair dyeing power and low background stain and is excellent in agent stability.
