Coat clean, wet or dry hair with a thick, generous coating of Straightening Hair Masque. Comb it through from roots to ends to distribute the product evenly. Leave on until the masque dries to a hard shell. (To help the treatment sink in further, wrap hair in a hot towel, or use blow-dry on a warm setting to speed the drying process). DO NOT SHAMPOO OFF. Simply rinse well and commence styling.
