EXOTHERMIC HAIR COLOR COMPOSITION

摘要

A composition for coloring hair is disclosed. The composition comprises, in a cosmetically acceptable solvent, at least one reducing agent with a concentration up to 2 wt. % of the composition, preferably up to 1 wt. %. Optionally, the composition comprises at least one coloring agent. The composition is free of ammonia and free of p-phenylenediamine (PPD). The mixing of the composition for coloring hair with an oxidizing composition launches an exothermic chemical reaction providing heat with a temperature that increases from room temperature TR to a temperature ranging from about (TR+3)° C. to about (TR+20)° C. A kit and a method for changing hair color are also disclosed. The compositions and methods are achieving color change results and white hair coverage with larger dye molecules than PPD, in an ammonia free environment. The exothermic properties allow obtaining uniform and rich hair colors in without ammonia or PPD.
