This formula has low molecular weight amino acids (90-150mw) which penetrate the hair and reconstruct the hair instantly. However in order to achieve these results it is necessary to cleanse the hair properly first. This formula is PH balanced at 3.5 to 4.5 which keeps it color safe and maintains the cuticle layer. It is safe to use every day if necessary and it will not build up, over-moisturize or dry out the hair. We recommend using instant conditioner before and/or after chemical services. IMPORTANT INGREDIENTS: CETEARYL ALCOHOL: A Moisturizer and emulsifier. CYCLOMETHICONE AND DIMETHICONOL: For shine and smoothness. KERATIN AMINO ACIDS: Repairs the hairs internal structure.
