Suitable for all hair and scalp types, OUAI’s Scalp Serum is a skincare-inspired formula designed to help hydrate your scalp and create an optimum environment for your hair. The serum is supercharged with hyaluronic acid to lock in moisture, supported by adaptogens, including arctic root, Siberian ginseng and chaga mushroom, to promote long-lasting hydration. Peptides encourage the appearance of thicker, fuller hair, while red clover flower extract helps to minimise the risk of disrupting the scalp during styling.
