PROBLEM TO BE SOLVED: To provide a hairdye composition having excellent resistance to factors in the atmosphere, e.g. light and bad weather, perspiration and various kinds of treatments (shampooing and transformation by permanent wave) to which the hair may be subjected, exhibiting low selectivity allowing the gray hair to be dyed, and capable of imparting a color having stronger chromaticity without causing important deterioration in the hair. SOLUTION: The ready-to-use composition for oxidation dyeing of the keratinic fiber, especially the human keratinous fiber such as the hair contains at least one first oxidation base selected from p-phenylenediamines, at least one second oxidation base selected from p-aminophenols, at least one coupler selected from m-aminophenols, m-phenylenediamines and m-diphenols, and at least one enzyme such as laccase. The dyeing method uses the composition. COPYRIGHT: (C)2006,JPO&NCIPI
