No. 3 is the third step of the Olaplex protocol and is intended for the general public. Its goal is to help restore capillary bonds. This product should be applied at home before shampooing and can be used more than once a week.

How to use: Apply a generous amount of product from roots to ends on unwashed hair. Distribute the product with a comb and leave to act for 10 minutes. On damaged hair, repeat the application without rinsing. Rinse and proceed with shampooing.

Use once a week between two chemical treatments to strengthen damaged hair, or the day before a chemical treatment, as a pre-treatment.
