The Science

A synergistic blend of skincare actives and superfoods

Ceramide NG

A clinically proven skincare active, ceramides repair the structural integrity of hair by sealing the cuticle, locking in moisture. Less damage and breakage, better colour retention and resilience.

Argan Oil

Known as ‘liquid gold,’ argan oil is rich in linoleic acid and vitamin E, replenishing the fatty acids and moisture stripped by bleach and colour to make blonde hair softer, shinier, golden.
