PROCESS FOR DYEING AND STRAIGHTENING HAIR

摘要

The present invention relates to a method for dyeing and semipermanent straightening of the hair in two steps, which are carried out one after another in one salon visit. The method uses a first composition (dye composition) comprising at least one hair dye, optionally at least one alkalizing agent and optionally at least one oxidizing agent, and a second composition (straightening composition) comprising at least one carboxylic acid of the Formula (I) : R-CO-COOH. The hair is treated with the said compositions successively, so that the straightening treatment is performed directly after the colouring treatment.
