Schwarzkopf BC Bonacure Volume Boost Shampoo delivers a boost of volume and leaves hair feeling thicker and fuller for up to 48 hours. Formulated for fine and weak hair, the shampoo improves volume, body and bounce. Schwarzkopf BC Volume Boost Shampoo: New Technology for Healthy & Voluminous Hair The shampoo features advanced technologies, including Vegan Care Complex with a vegan keratin alternative & creatine. The secret of the Schwarzkopf Volume Boost shampoo lies in the combined power of vegan keratin and creatine. The formulation with keratin restores the hair fibre, ensures suppleness and improves manageability. At the same time, creatine gives each strand more volume, body and bounce. How Schwarzkopf BC Bonacure Volume Boost Shampoo works Bonacure Volume Boost Shampoo gently removes excess sebum and product build-up which can weigh the hair down. Special care polymers prevent static while improving manageability and hair elasticity. The product is free from SLS/SLES, silicones and artificial colourants. The shampoo with vegan keratin strengthens the hair from the inside out and leaves it feeling fuller and thicker for up to 48 hours.
