Deeply nourish damaged, colour-treated hair with this two-part Briogeo Don't Despair, Repair! Deep Conditioning Hair Cap System ($36), which earns an average 4.6-star rating from other Sephora shoppers. There's an argan-oil rich mask that helps rebuild and protect — and it works twice as well when the heat and steam locked in the cap allow nutrients to better absorb into hair. Your styles will be shinier and stronger when you're done (thanks to biotin, panthenol, and algae extract, too).
There's also the popular Briogeo Don't Despair, Repair! Deep Conditioning Mask ($36) without the cap which has earned nearly 1,500 5-star reviews on its own.
