The reset your locks have been longing for, OUAI Detox Shampoo Refill Pouch (946ml) helps to cleanse away dirt, excess oil and product build-up (we're looking at you , dry shampoo). If shampoo was a car wash service (bear with us here), this would be the equivalent of a full valet. A once-a-week option, its gentle formula boasts apple cider vinegar to help cut through product build-up and neutralise shine-compromising hard water deposits while hydrolysed keratin works to support brittle or heat-weakened tresses. Expect to be left with hair that feels soft, silky and ready for action. Infused with the brand's signature 'Melrose Place' fragrance, a harmony of rose, lychee, bergamot, cedarwood and white musk is the perfect final flourish.
