A purifying shampoo for fine and weak hair. Schwarzkopf BC Collagen Volume Boost Micellar Shampoo gently removes excess oil and residues that can weigh the hair down. Care polymers are added to prevent static for better manageability of the hair. Additional thickeners create a gel-like consistency and make the hair feel fuller. Hair feels fuller for up to 3 days with up to 100% improvement in volume, giving even fine hair lasting body with a natural shine. This shampoo is cruelty-free.
