Provided is a hair dye composition containing a direct dye (1). This hair dye composition has markedly high hair dyeing power, has less color fade over time and undergoes a small change in the color tone of the dye even after storage. <CHEM> wherein, R<1> to R<4> each represents a (substituted) C1-6 alkyl group, (substituted) alkenyl group or (substituted) aryl group or R<3> and R<4>, when taken together with the adjacent C, form a 5 to 12 membered ring, R<5> represents H, (substituted) C1-6 alkyl group, (substituted) alkenyl group, (substituted) aryl group or acyl group, X<1> and X<2> each represents H or halogen atom, Y<1> and Y<2> each represents H, (substituted) C1-6 alkyl group, (substituted) alkenyl group, (substituted) C1-6 alkoxy group or halogen atom, Z<1> and Z<2> each represents H, (substituted) C1-6 alkyl group, (substituted) alkenyl group, (substituted) C1-6 alkoxy group, nitro group or halogen atom, and A<-> represents an anion. |
