Abstract
A subject-matter of the invention is a composition comprising a) at least one ortho-diphenol derivative, b) at least one specific metal derivative and c) at least one basifying agent, a method for dyeing keratinous fibers by treatment of the said fibers using the ingredients a), b) et c) and the use thereof for dyeing keratinous fibers. This hair dyeing method makes it possible to obtain better colorations which are more uniform, chromatic and lasting and which do not detrimentally affect the cosmetic properties of the keratinous fibers, starting from an extract of ortho-diphenols which are in particular natural.
