Wheat Amino Acids: A blend of amino acids from wheat protein that has been broken down via hydrolysis - a process using water to extract the acids. Used as a conditioning and hydration agent for normal, chemically treated and heat-damaged hair. Their small molecule size is able to penetrate the hair shaft and deliver moisturizing and conditioning benefits to repair and protect the all-important keratin. It increases the elasticity, flexibility, and strength of the hair, reducing breakage and frizz, and improving the manageability and condition of the hair.
