OUAI Scalp Serum Thicker Fuller Hair 2 Fl Oz

OUAI Scalp Serum is a leave-in treatment formulated to support a healthier-looking scalp environment as a foundation for thicker, fuller-appearing hair. The formula combines exfoliating acids, including salicylic and lactic acid, with soothing and conditioning ingredients to help clear away buildup from oil, product residue, and dead skin cells that can accumulate at the root. OUAI, founded by celebrity hairstylist Jen Atkin, built its scalp-care line around the idea that scalp health is the starting point for stronger, more voluminous hair over time.

To use, apply the serum directly to the scalp on clean, towel-dried or dry hair, focusing on areas that feel oily, flaky, or congested, then style as usual without rinsing. Regular use is intended to leave the scalp feeling refreshed and balanced while helping minimize the look of thinning by supporting a cleaner follicle environment. It's best suited to those dealing with scalp buildup, oiliness, or looking to add a targeted step to an existing hair-care routine.

What's Included: One 2 Fl Oz OUAI Scalp Serum, genuine and sourced from authorized channels.
