Olaplex No 4P Blonde Enhancer Toning Shampoo 1000ml is a professional-grade cleansing treatment formulated to preserve and enhance blonde, bleached, gray, and white hair. Combining Olaplex bond-building technology with a specialized purple toning system, this shampoo neutralizes yellow and brassy tones while strengthening the hair fiber from within. The result is a cooler, more vibrant blonde with improved resilience and a healthy-looking finish.

Gentle yet effective, No 4P Blonde Enhancer delivers moisture and softness without weighing hair down. Free from sulfates, parabens, and phthalates, this formula is suitable for sensitive scalps and for use on color-treated hair. With regular use, it helps maintain salon-quality tone between appointments and supports overall hair integrity by repairing and protecting broken bonds.

Directions for use: apply to wet hair, lather, leave on for 1–3 minutes depending on desired toning intensity, then rinse thoroughly. For optimal results, follow with Olaplex No 5 Conditioner or other Olaplex treatments to lock in moisture and further reinforce hair structure.
