Key ingredients
Olaplex’s signature bond-building ingredient, included to help support damaged links within the hair structure during cleansing.
A mild surfactant that lifts dirt and oil while remaining gentler than traditional sulphates.
A coconut-derived co-surfactant that helps create a soft lather and supports a less stripping wash.
A humectant that draws in moisture so hair feels less dry after rinsing.
