OUAI Thick Hair Shampoo is a deeply moisturizing, frizz-fighting shampoo formulated specifically for thick hair that needs a rich, thorough cleanse without being stripped of moisture. Marshmallow root detangles and softens, shea butter delivers deep hydration, and avocado oil smooths frizz and adds the shine customers consistently call out in reviews, leaving hair silky soft from root to ends. Gentle enough for daily use, it lathers luxuriously and rinses clean, and is sulfate-free, paraben-free, and phthalate-free, making it a strong option for thick hair types who want a clean formula that does not compromise on performance. Color-safe and compatible with keratin-treated, chemically-processed, extension, wig, and synthetic hair, there are no trade-offs for how you treat or style your hair. Pair it with OUAI Thick Conditioner to lock in moisture and complete the frizz-control routine, or layer in OUAI Leave-In Conditioner for added detangling and heat protection, all from OUAI, the hair, body, and fragrance brand built to take you wherever you go. Scented with Mercer Street, featuring notes of Italian lemon, jasmine, and white musk, the fragrance is one of the first things customers mention alongside how well it works for thick hair.
