PROBLEM TO BE SOLVED: To provide a dyeing composition ready for use, which reduces deterioration of keratin fibers at the time of dyeing and provides strong coloring. SOLUTION: An oxidation dye, a two- or four-electron oxidoreductase type enzyme and a specific chlorinated or chemically modified chitosan are contained in a medium suitable for dyeing, and keratin fibers, particularly human hair such as hair, are contained. A composition ready for use for oxidative dyeing of keratin fibers. |
