Invigorate and fortify the appearance of fine, limp locks with the OUAI Fine Hair Shampoo. This shampoo works to add weightless body to thinner tresses while gently lifting away dirt, grime and product build-up. Powered by beneficial ingredients, the hair treatment charges flat, duller-looking locks with a new lease of life. Hydrolysed Keratin promotes a silky-smooth finish, filling in missing keratin found naturally in the hair follicle to tame fly-aways and frizz. Biotin releases strengthening properties to enhance strands with increased resilience. Hemp Seed Extract hydrates and conditions while Chia Seed Oil creates the illusion of thicker, more voluminous hair. This volumising shampoo delivers essential nutrients to thinner locks as it adds shape to the roots and lengths, leaving tresses clean, bouncy and full of life.
