Great hair starts here. Protect and replenish the protective lipid layer that locks in moisture to give hair its natural smoothness, gloss, and ability to reflect light. This first of its kind traceless serum-the first step post-shower-weightlessly hydrates and repairs the all-important F-layer, and preps hair for styling thanks to vitamin- and mineral-rich Fruit Water Extracts and the nourishing Oil Botanical Blend.
