How to Use Olaplex No.3 Hair Perfector

Olaplex No.3 Hair Perfector is a pre-shampoo treatment, so it goes on before you wash your hair. The directions at retailers such as Skinsort say to apply a generous amount from roots to ends on damp, towel-dried hair, comb through once and leave it on for at least 10 minutes, then rinse, shampoo and condition.

Step by step

• Towel-dry your hair so it is damp but not dripping.
• Apply a generous amount from roots to ends.
• Comb through once.
• Leave it on for 10 minutes or longer.
• Rinse, then shampoo and condition as usual.

How often?

Community data collected by Skinsort shows people using it in a range of ways, from every day to weekly, but the brand’s own pack directions should come first. If you are unsure, start weekly and see how your hair feels.

How long does a bottle last?

That depends on your hair length and thickness and how often you use it, so there is no single answer. Using the amount recommended on the pack rather than a tiny dab gives the intended result.

Check the directions on your own bottle, and speak to a hairdresser if you have scalp irritation or very damaged hair.
