This fluid clay has a purifying action on the scalp that helps regulate the production of sebum, while conditioning and hydrating the hair without making it heavy. How it works:Bentonite (a clay of volcanic region with absorbent properties) permits the natural removal of excess sebum. Burnet and Cinnamon Extracts were added to normalize sebum production and have an anti-odor effect by inhibiting bacterial proliferation. Azeloglycine regulates sebum while hydrating and giving hair increased elasticity. How to use:We recommend applying after shampooing with Rebalancing Sebum Control Shampoo. Delicately massage the correct amount of product uniformly on the scalp. Leave for 5-10 minutes and then carefully rinse. If necessary, use also on the ends of the hair.
