Schwarzkopf Professional BC Bonacure Color Freeze Sulfate-Free Shampoo is a gentle formula for color-treated hair, that brings hair to its optimal pH 4.5 level to perfectly freeze color pigments. The shampoo lightly cleanses your hair without compromising its colour. Added UV filters protect hair from damaging ultraviolet radiation so that every single strand is protected from colour fade day after day. This all-round boosting shampoo works to enhance the healthy look of hair with balancing and moisturising ingredients while its protective formula promises up to 90% colour retention. As it is sulphate free, this shampoo produces less foam than standard shampoos, and it's also suitable as a post colour shampoo for dry, porous and damaged hair. Features: * Sulfate-free shampoo for coloured hair that gently yet effectively cleanses colored hair * Tightens and stabilises the matrix thus keeping the color pigments frozen deep inside the hair * Works to neutralise chemical residues while smoothening hair structure * Provides special UV filters that protect hair from environmental effects * Suitable for porous and colour-treated, highlighted or over-processed hair * This product is cruelty-free
