Keep blonde, lightened and grey hair looking bright and fresh with OLAPLEX No. 4P Blonde Enhancer Toning Shampoo. This highly concentrated purple shampoo cleanses the hair while depositing violet pigments that help neutralize unwanted yellow and brassy tones.
 
Designed to provide toning benefits without sacrificing the condition of the hair, No. 4P also helps leave hair feeling hydrated, stronger and more manageable after washing. It is a great addition to your routine between salon appointments when your blonde begins to look warmer or duller than you'd like.
 
Ideal for blonde, bleached, highlighted, lightened and naturally grey hair. The longer the shampoo is left on the hair, the more intense the toning effect can be, so usage can be adjusted depending on your desired result.
 
Best for: Blonde, highlighted, lightened or grey hair experiencing yellow or brassy tones.
