Olaplex Blonde Enhancer No.4p Shampoo 250ml

Neutralize brassy yellow and orange tones in blonde, highlighted, and graying hair while reinforcing structural integrity. Olaplex Nº4p Blonde Enhancer Toning Shampoo deposits corrective violet and blue pigments within a formulation engineered specifically for lightened and chemically processed textiles.

This dual-action product operates as both a toning shampoo and an intensive color-depositing treatment. When used regularly, it cleanses and gradually neutralizes unwanted warmth to maintain cool, bright reflections. For rapid correction of persistent brassiness, apply directly to damp hair after an initial wash and leave the product active for up to ten minutes before rinsing. Adjust application intervals based on how quickly tone shifts occur in your specific hair condition.

Embedded with Bond Building Technology, the formula identifies and repairs broken disulfide bonds caused by bleaching, coloring, and thermal stress. This molecular reconstruction happens concurrently with pigment deposition, preventing further degradation during the toning process. The pigment load effectively targets a broad spectrum of yellow, orange, and brassy issues, making it suitable for platinum, silver, balayage, and all degrees of gold blonde.
