Olaplex is the new, revolutionary take-home treatment that helps to permanently rebuild damaged hair, particularly if it's been damaged by colouring, relaxing and heated styling. Olaplex is a single active ingredient, designed to reconnect the disulfi de sulfur bonds broken by the process of permanent hair coloring and lightening. Olaplex is free of silicones, oils, aldehydes and parabens. Apply from roots to ends on unwashed towel-dried hair. Leave for a minimum of 10 minutes. Rinse hair, shampoo and condition.
