Abstract
The present invention relates to a process for dyeing keratin fibers, in particular human keratin fibers such as the hair, comprising the use of one or more metal catalysts chosen from transition metal salts and rare-earth metal salts, and mixtures thereof and a composition (I) comprising at least 10% by weight of one or more fatty substances different from fatty acids, one or more oxidation dyes and one or more oxidizing agents.
Claims18
A process for dyeing keratin fibres, comprising the use of one or more metal catalysts chosen from transition metal salts and rare-earth metal salts, and mixtures thereof, and of a composition (I) comprising:
- at least 10% of one or more fatty substances different from fatty acids relative to the total weight of composition (I),
- one or more oxidation dyes, and
- one or more oxidizing agents;
- wherein the one or more metal catalysts and the composition (I) provide a homogeneous coloration along the keratin fibres, when applied to the keratin fibres.
