OUAI Thick Hair Mask

By Jamie Lin, Reviews Editor||How we test

Rich, buttery deep-conditioning mask made for thick hair, with hydrolyzed keratin, almond, macadamia and olive oils, and shea and illipe butters.

OUAI Thick Hair Mask is the rich, buttery member of OUAI's mask lineup — made for thick hair rather than every hair type. The formula pairs hydrolyzed keratin with almond, macadamia, and olive oils plus shea and illipe butters to restore deep moisture, fight frizz, smooth split ends, and help prevent future breakage.

After shampooing, comb it through damp mid-lengths to ends, leave it on for a few minutes, and rinse with cool water to seal in shine. It is safe for color-treated, keratin-treated, and chemically treated hair, is made without sulfates (SLS/SLES), parabens, and phthalates, and is cruelty-free and gluten-free. The scent is Melrose Place, a velvety-rich rosy blend with notes of rose, lychee, berry, and pink peppercorn.

At current pricing for 8 oz, it's a premium purchase but competitive with other luxury masks. Because the formula is built for thick, dry, or damaged hair, shoppers with fine hair should look at a lighter mask instead.
