Jump aboard! The Fine-Medium Hair Treatment Masque (236ml) is your one OUAI ticket to hydrated, healthy and fuller-looking locks. A rich fusion of shea butter and panthenol packs this luxurious weekly treatment with a moisturising punch (not to mention its velvety texture, which is so buttery you'd be forgiven for wanting to spread it on toast). The ultimate indulgence for fine and medium hair types, it boasts a blend of hydrolysed keratin and coconut water to restore moisture and sooth damage without weighing strands down. The pièce de résistance ? An infusion of the fresh and floral Melrose Place fragrance; a little L.A sunshine bottled, just for you... and your hair.
