L'Oreal Professionnel's Scalp Advanced Anti-Oiliness Shampoo was targeted-formulated for oily scalps. Scalp is skin, but a much more complex one. Sebum oxidation and micro cracks on the scalp surface can create oiliness and clogging. It’s a vicious cycle and you want out. This lightweight gel purifies the scalp and the fiber from residue, sweat and oil for a fresher and cleaner feel. Concentrated with 3% AHA, water-soluble acid. It helps to purify the surface of the scalp so that new cells can generate. It brings more volume to the hair and up to 78% less scalp sebum in one use*.
