Revive healthy-looking shine and thickness with the OUAI Fine Hair Shampoo Refill (946ml). This volumising staple is designed to rewrite your hair's fate, especially if your tresses tend to be flat. It boasts a nourishing blend of hydrolysed keratin, biotin, hemp, and chia seed oils, creating a weightless formula that supports root-to-tip thickness. The iconic 'Mercer Street' fragrance, a delicate blend of orange, peony, magnolia, jasmine, and musk, provides a perfect finishing touch even after rinsing. This shampoo is easy to use with a mess-free nozzle, offers space-efficient storage, and allows for zero product waste with its squeezable pouch. The lightweight pouch also contributes to a reduced carbon footprint during manufacturing and transport.
