Ingredient highlight for Sakura Scalp Scrub. Sakura: new cherry blossom scent, inspired by sakura, the national flower of Japan. Sake water: A natural source of probiotics that restores and balances the scalp's natural pH level. Platinum fiber: delivers a platinum-like shine without adding extra weight. Sugar: Gentle sugar crystals lightly exfoliate the hair and scalp to remove product and oil build up. Hyaluronic acid: can absorb 1000 times its own weight to secure moisture and add fullness to hair.
