Invigorate and fortify the appearance of fine, limp locks with the OUAI Fine Hair Shampoo. This nourishing shampoo works to add weightless body and volume to lacklustre tresses while gently lifting away any dirt, grime and product build-up lingering at the scalp and ends. Powered by a cocktail of beneficial ingredients, the hair treatment helps to charge 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 and definition to both the roots and lengths, leaving tresses clean, bouncy and full of life.
