Biolage's Volume Boost Shampoo works to infuse limp lengths with renewed body and bounce. Infused with hydrating actives, the cleansing lather sloughs away build-up and impurities that can weigh hair down. Infused with micro-filtered soy protein and polymers, the shampoo is specially designed to promote volume without compromising on softness. The lightweight blend weightlessly hydrates as it cleanses, for enhanced shine and smoothness.
