The OUAI Fine Hair Shampoo is designed to add weightless body while gently cleansing away dirt, excess oil and product buildup. Infused with a blend of potent ingredients, the shampoo revamps flat, dull hair to help boost volume and bounce. Hydrolysed keratin creates a silky-smooth finish by replenishing the hair with moisture and taming flyaways, while chia seed oil promotes thicker, more voluminous-looking hair. Biotin seeks to strengthen the look of strands, while hemp seed extract hydrates and conditions. The volumising shampoo nourishes fine hair, lifting roots and adding shape to leave your strands clean, glossy and full of life.
