Purify your tresses with the OUAI Detox Shampoo Refill Pouch. This concentrated hair cleanser is designed to lift and remove dirt, oil, impurities and build-up from styling products and hard water deposits. Now in a refill formula, you can minimise package waste by opting for this sustainable pouch. The shampoo itself instantly refreshes the scalp, roots and lengths without stripping, drying or fading out your colour. Its gentle formula is free from harmful chemicals and preservatives, making it safe to use on all hair types and textures, including colour-treated, keratin-treated hair and Brazilian blow-outs. Creating a rich lather upon contact with water, the formula swiftly eliminates stubborn dry shampoo and styling waxes to leave your hair soft, shiny and supple. Apple Cider Vinegar helps strengthen weakened tresses, improve lustre by lowering the pH levels of the hair and scalp, and alleviates itchiness with soothing properties. Hydrolysed Keratin smooths splintered hair fibres and tames frizz to leave your mane with an incredible halo of blinding shine. Safe for use on all hair types, even colour- or keratin-treated. Free of SLS, SLES, phthalates and parabens.
