Abstract:
The invention relates to a process for dyeing keratin fibers, in which said fibers are treated: ▪ with a composition (A) comprising i) one or more indole or indoline compounds; ii) one or more metal salts; iii) hydrogen peroxide or one or more systems that generate hydrogen peroxide; and then ▪ with a composition (B) comprising iv) one or more basifying agents. The invention also relates to a hair dyeing process for obtaining better colorations, which are more uniform, chromatic and remanent and which do not impair the cosmetic properties of keratin fibers.
