Olaplex No. 4P Blonde Enhancer Toning Shampoo, 8.5 oz

Tone & Repair In One Step

Purple shampoo that actually works—and repairs your hair while it tones. No.4P neutralizes brass and yellow tones in blonde, grey, and highlighted hair while Olaplex technology rebuilds broken bonds.

Most purple shampoos leave blonde hair feeling dry and straw-like. This one leaves it toned, strong, and genuinely healthier. Your blonde stays bright without sacrificing hair integrity.

Best For: Blondes, silver/grey hair, highlights, anyone fighting brassiness.

How To Use:

Massage into wet hair and lather. Leave on 1-3 minutes depending on desired toning intensity. Rinse and follow with No.5P or No.5 Conditioner.
