If glamorous credentials matter when choosing your hair care products, then let us introduce you to OAUI, the brand created by celebrity hairstylist and entrepreneur Jen Atkin—who is also the mastermind behind Mane Addicts, the all-things-hair digital hub with more than half a million followers on Instagram. Nordstrom's lineup of OUAI hair care products includes OUAI Wave Spray, a magical mist made with rice protein, and OUAI Hair Oil, which delivers a glossy, sleek finish while preventing heat damage and fighting frizz. OUAI is also famous for its core offerings of shampoos and conditioners for all hair types, plus dry shampoos and volumizing sprays. (And did we mention that the entire OUAI hair care line is paraben free, phthalate free and sulfate free? It is!) Also be sure to check out the brand's limited-edition perfumes and luxurious bath and body products. You'll always find the best of OUAI—it's pronounced "way" by the way!—and other top hair care brands at Nordstrom.
