Abstract

The present disclosure relates to a process for permanently reshaping hair, comprising: applying, to an area to be reshaped, a solution comprising at least one polymer chosen from anionic and amphoteric polymers in a medium comprising water and, optionally, at least one cosmetically acceptable solvent, applying, to the area treated in step (a), a reducing composition comprising at least one reducing agent that is capable of cleaving disulfide linkages of the hair and a sufficient amount of ions chosen from metal cations and ammonium ions to precipitate in situ the at least one polymer, shaping the hair in the area treated, followed by a leave-in time for the reducing composition, applying, to the area treated in steps (a) and (b), a fixing composition comprising at least one oxidizing agent, followed by a leave-in time for the fixing composition, and rinsing the hair, and also to a multi-component agent and a multi-compartment kit for the same.

Description

technical field [0001] The present invention relates to a method of permanently reshaping hair comprising an insitu deposition step of a water-soluble polymer, and a multi-component agent for carrying out this method. Background technique [0002] One of the methods currently used to permanently reshape hair is to sequentially treat it with a reducing agent capable of cleaving the disulfide bridges of keratin, followed by an oxidizing agent that rebuilds the disulfide bridges, while under mechanical constraints, e.g. Secure hair with curlers. [0003] The traction applied by the curlers can separate the hair roots, but it also includes undulating the hair. Today, many women wish to increase the amount of their frizz-free hair. [0004] Granted, large curling irons can be used to tone down the curly look and just get micro waves, but the fixation for this permanent reshaping is not very good. [0005] Another disadvantage of conventional permanent restyling methods is hair...
