The Schwarzkopf Professional BC Bonacure Volume Boost conditioner for fine and weak hair lifts every single strand from the roots and gives it the maximum possible volume for up to 48 hours. Its unique lightweight jelly texture nourishes the hair, improves its inner strength and helps with easy detangling. At the same time, it gives the hairstyle maximum fullness, bounce and an anti-static effect. The result is beautifully shiny, voluminous and healthy-looking hair.
