The perfect antidote for severely dry, damaged and brittle hair that needs instant TLC, this clinically proven genie in a bottle stars innovative ingredients to repair damage along the hair cuticle and leave locks stronger, smoother and more hydrated. Rather than coating strands with silicones to give a short-term illusion of healthier hair, Don't Despair, Repair! Strength + Moisture Leave-In Mask utilises the power of micro-encapsulated argan oil, which packs tightly within the damaged area to close structural gaps and release a protective layer on the hair shaft. Alongside this, algae extract contains potent vitamins and minerals to nourish and strengthen strands, while biotin bolsters both shaft and follicle to prevent further damage. Deeply reparative, it noticeably reduces breakage after just one use and is, quite simply, too good to wash out.
