The Olaplex No.4P Blonde Enhancer Toning Shampoo (250ml) is a highly concentrated purple shampoo that tones, strengthens, and brightens blonde, lightened, and grey hair. Powered by patented Olaplex Bond Building Technology™, it neutralises unwanted brassiness while repairing from within for visibly healthier, more radiant results.
Unlike traditional purple shampoos, No.4P delivers customised toning — the longer you leave it, the brighter the result — without drying or dulling the hair. Its gentle, sulphate-free formula provides deep cleansing while improving softness, smoothness, and shine.
