Schwarzkopf Bonacure pH 4.5 Color Freeze Spray Conditioner is designed for colour treated, highlighted and slightly porous hair. Nourishing ingredients fill structural gaps in the outer layer of the hair, improving the elasticity and strength of colour-treated hair. Hair is brought to the optimal pH level of 4.5, helping to prevent colour fade. A high proportion of silicone oils immediately improve manageability and adds brilliant shine. Shake well and spray onto pre-shampooed, towel dried hair. Do not rinse.
