Schwarzkopf BC pH 4.5 colour freeze conditioner is a rich creamy conditioner for colour-treated hair. This high-performance formula with pH 4.5 balancer technology instantly tightens the inner hair structure to deeply freeze colour pigments into the matrix, while the lightweight cationic actives deposit on the outer layer close the cuticle. Cell perfector technology seals the surface of the hair, imparting extra care and reducing colour fade virtually to zero. Comes in 1000 ml. Formula detangles and improves compatibility while reviving dull colours. Helps to optimise the pH level to 4.5. Works to strengthen the hair structure.
