Olaplex No.4P Blonde Enhancer Toning Shampoo 1 Litre is a highly concentrated purple toning shampoo designed for professional salon backwash use. Powered by Olaplex’s patented bond-building technology, this advanced formula helps repair everyday hair damage while strengthening weakened hair bonds to improve resilience and overall hair health.
Ideal for professional and freelance hairdressers, stylists, and colour technicians, this ultra-pigmented violet shampoo neutralises unwanted yellow tones and brassiness in blonde, lightened, and grey hair. The hydrating lather gently cleanses the hair and scalp while enhancing brightness, softness, and shine, leaving hair visibly brighter, smoother, and more evenly toned after just one wash.
