All-Nutrient Lightener Control is a lightener additive designed to improve the lightening action and healthiness of hair. Lightener Control is a resin-based gel, infused with a blend of Keratin, amino acids, essential fatty acids, and humectants that act on the three primary components of hair: tensile strength, elasticity and cuticle abrasion. Quaternized Keratin Proteins penetrate the hair and strengthen each strand. Humectants adhere to the hair shaft and replenish moisture. An exclusive Amino Acid Technology rebuilds the bonds of the hair. Essential Fatty Acids prevent breakage and buffer against the harmful effects of lightening. Made with natural organic extracts.
