Top features
OUAI Scalp Serum is a skin-care-inspired scalp treatment combining hyaluronic acid with adaptogenic botanicals—Siberian Ginseng, Arctic Root, and Chaga Mushroom—plus peptides to support scalp hydration and the appearance of thicker, fuller hair. Applied daily via dropper to the scalp, it's designed to reduce discomfort and create a healthy scalp barrier for all hair types. The formula is paraben-, phthalate-, and sulfate-free and carries OUAI's signature Cape Town scent (spearmint, ginger, basil, green fig). Reviews praise scalp calming and hydration; growth claims remain largely anecdotal. At $27/oz, it sits in the premium mid-tier, justified more by brand trust and botanical blend than clinical density evidence. Community sentiment is moderately positive, with users noting it soothes dry scalp but cautioning that it's primarily a hydrating serum, not a proven growth accelerator.
