Olaplex No. 4P Blonde Enhancer Toning Shampoo is a highly concentrated, sulfate-free formula designed to neutralize unwanted brassiness and yellow tones, leaving blonde, gray, and lightened hair brighter and cooler after just one use. Infused with Olaplex’s patented Bond Building Technology, this violet-pigmented shampoo strengthens and repairs hair from the inside out while gently cleansing without stripping or drying. 

How To Use:

Apply to wet hair, lather, and leave for 1-3 minutes. Rinse thoroughly. Use 2-3 times weekly and follow with Olaplex No. 5 Conditioner for best results.
