Elevate blonde care with the Olaplex No.4P Blonde Enhancer Toning Shampoo, a professional-grade formula designed to neutralise brassiness while hydrating and brightening hair.

Powered by Olaplex’s original Bond-Builder System, the shampoo targets dryness and brittleness, leaving hair softer, shinier, and easier to manage. Infused with highly concentrated purple pigments, it delivers adjustable toning—the longer it is left on, the more luminous the results. Perfect for maintaining all-over blonde, balayage, or naturally light hair.
