Performing as a shampoo and a detoxifying mask, the L’Oréal Professionnel Serié Expert Deep Purifier Mask leaves hair feeling refreshed. Ideal for oily hair types, the formula utilises a blend of kaolin clay and charcoal to help remove impurities, sweat and excess sebum from the scalp, without stripping away moisture. The multi-purpose mask delivers a volume boost for a more full-bodied look.
