For professional use only Created especially for use on color treated hair, Multi-Protein Straightening System contains a purple pigment, blocking any red, yellow or orange brassiness that may otherwise occur during treatment. Multi-Protein Straightening System Penetrates the hair, promoting a re-balance of the molecular structure. This, not only provides greater control over the degree of straightening, smoothing or defrizzing the hair that can be achieved, it also restores hair to health and provides excellent, long-lasting results – leaving the hair looking shiny and feeling revitalized.
