Olaplex No.4p Blonde Enhancer Toning Shampoo 250ml

OLAPLEX uses patented technology to fortify brittle hair bonds for a healthy-looking appearance. It strengthens the hair, neutralises any brassiness using violet pigments - ideal for long-wearing cool blonde or grey tones.

The shampoo is ideal for colour-treated or natural hair, suitable for all hair types and can be used on a daily basis. The highly concentrated, sulphate-free formula allows for customisable toning effects: the longer the shampoo is kept on the hair, the lighter the results will be.
