Olaplex No. 3 Hair Perfector is designed to repair bonds in the hair broken by colouring, lightening or heat styling. It multiplies, rebuilds and bonds to reduce breakage whilst making colour last much longer
Apply a generous amount to wet towel-dried hair and leave on for a minimum of 10 minutes. Rinse thouroughly, shampoo and condition. We recommend the Alterna Caviar Repair X shampoo and conditioner.
The longer the Olaplex No 3 is left on the hair, the more effective it will be, it cannot be left on for too long. However this is NOT a conditioning treatment to be left on the hair, it should always be shampooed out.
