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.

Key Benefits:

• Neutralises yellow and brassy tones in blonde, bleached, and grey hair

• Strengthens and repairs bonds to reduce breakage

• Enhances brightness and clarity of lightened hair

• Leaves hair soft, shiny, and manageable

• Colour-safe, sulphate-free, and suitable for all lightened tones

How to Use:

1. Apply to wet hair, lather, and leave on for 1–3 minutes (longer for more intense toning).

2. Rinse thoroughly.

3. Follow with Olaplex No.5 Bond Maintenance Conditioner or No.5P Blonde Enhancer Conditioner for added hydration.

4. Use 1–2 times per week in place of your regular shampoo.

Reveal brighter, cooler tones and healthier hair with the Olaplex No.4P Blonde Enhancer Toning Shampoo — the purple shampoo that repairs as it tones.
