Abstract:
A process for protecting the color of artificially colored keratin fibers against the effects of UV radiation, comprising dyeing said artificially colored keratin fibers according to an oxidation dyeing process using at least one oxidation dye precursor, at least one oxidation agent, and an effective amount of at least one organosiloxane containing at least one unit of formula (I) below: wherein:Râ€², which may be identical or different, is chosen from saturated and unsaturated C1-C30 hydrocarbon groups, C1-C8 halogenated hydrocarbon groups, an aromatic hydrocarbon group, and a trimethylsiloxy group; a is equal to 1 or 2; and T is equal to (â€”Eâ€”U), wherein E is chosen from saturated and unsaturated, linear and branched aliphatic divalent hydrocarbon radicals having at least 2 carbon atoms and optionally containing at least one oxygen atom, or alternatively an aromatic group, and U denotes the residue of a molecule which screens ultraviolet radiation.
