Abstract

The present disclosure concerns a multi-component packing unit (kit of parts) for reshaping and coloring keratinous fibers, more particularly human hair, comprising at least two separately packaged preparations (A) and (B), the first preparation (A) comprising, in a cosmetic vehicle (A1), one or more resorcinol derivatives from the group consisting of resorcinol, 2-methylresorcinol and 4-chlororesorcinol, and (A2) one or more oxidation dye precursors from the group consisting of p-phenylenediamines, p-aminophenols, 2,4,5,6-tetraaminopyrimidines and 4,5-diaminopyrazoles, and the second preparation (B) comprising, in a cosmetic vehicle (B1), hydrogen peroxide, wherein the molar ratio of all resorcinol derivatives (A1) in the preparation (A) to all developer-type oxidation dyes (A2) in the preparation (A), i.e. the molar ratio (A1)/(A2), is at least about 1.2.
