KERATIN AMINO ACID - This amino acid helps to restructure damaged hair CYSTEINE - Amino acid peptide bond constructing up to 18% of your hair that provides strength, shine and structure. Cysteine increases hair shaft diameter and hair growth density. Cysteine is a powerful cell defender acting as an antioxidant and also contains sulfur, known as nature's beauty mineral. A deficiency in sulfur is characterized by atrophied sebaceous glands which lubricate the scalp from the Essential Fatty Acids. In order for Cysteine to be effective it must synergistically work with ALL other aminos. A missing amino acid is like a missing building block that collapses the entire structure. DL-PANTHENOL (VITAMIN B-5) - This B vitamin is cationic, or positively charged which means that it is attracted to and absorbed into the hair. Vitamin B-5 is often called the "beautifier". It enhances the strength of hair and increases the resistance to breakage. It conditions without buildup and prevents damage caused by overheating and overdrying of hair and scalp. Panthenol nourishes hair by replenishing its level in the hair and imparts long lasting moisturization. When Panthenol penetrates the hair shaft a thin elastic film is left on the inside and outside of the shaft. This imparts flexibility and elasticity from the inside and luster from the outside. Panthenol can also thicken hair by up to 10%. SILICA - This mineral, derived from Springtime Horsetail Herb (Equisetum Arvense), improves strength and elasticity to the hair.
