Olaplex No. 4P Purple Toning Shampoo 8.5 oz

Olaplex's purple toning shampoo, made for blonde and highlighted hair that has started to pull warm.

Purple pigment counteracts the yellow and brassy tones that blondes drift towards between salon visits, while the formula carries Olaplex's bond-building technology — so you are toning without the extra dryness that purple shampoos are notorious for.

Particularly relevant if you have curls and highlights: coloured curly hair is dry to begin with, and a harsh toning shampoo makes that worse.

How to use

Use once or twice a week in place of your regular shampoo. Leave on for a few minutes for stronger toning, less time for a subtle result. Follow with the No. 5P conditioner.
