Olaplex No.0 Intensive Bond Building Hair Treatment and Olaplex No.3 Hair Perfector:
Olaplex No.0 Intensive Bond Building Hair Treatment: Apply Olaplex No.0 to DRY hair, fully saturating each section of your hair. Allow No.0 to process for 10 minutes. LEAVE IN HAIR.
Olaplex No.3 Hair Perfector: Apply a generous amount of Olaplex No.3 on top of the Olaplex No.0 and comb through from roots to end. Leave on for a minimum of 10 minutes again. Treatment is more effective the longer it is kept on for. When the time is up rinse, shampoo and condition the hair to finish.
No.3 needs a minimum of 10 minutes to work effectively. If hair is damaged, 20+ mins is recommended, 2-3 times per week. For healthy hair, once a week is ideal.
