OXIDATION COLORING PROCESS USING A SUBSTRATE CARRYING AT LEAST ONE OXIDATION DYE, MULTIPLE PRESERVATIVES, AND AQUEOUS OXIDIZING COMPOSITION

摘要

The present invention relates to a process for the oxidation dyeing of keratinous fibers, in particular human keratinous fibers such as the hair comprising a step of applying to said keratinous fibers i) a substrate comprising at its surface one or more oxidation dyes, one or more thiolated reducing agents, and one or more reductone-type organic reducing agents, and a step of applying to said keratinous fibers ii) an oxidizing aqueous composition comprising one or more oxidizing agents. The present invention also relates to a method of manufacturing said substrate. The invention also relates to a sheet element pretreated with a composition comprising one or more oxidation dyes, one or more thiolated reducing agents, and one or more organic reducing agents of the reductone type.
