OUAI Scalp Serum Balancing Scalp Treatment, 2 fl oz — Hyaluronic Acid & Adaptogens

OUAI Scalp Serum is a lightweight, skin-inspired scalp treatment formulated to hydrate the scalp, support fuller-looking hair, and soothe discomfort for all hair types.

Designed like skincare for your scalp, this serum combines hyaluronic acid with adaptogenic botanicals — Arctic Root, Siberian Ginseng, and Chaga Mushroom — to replenish moisture and help maintain a healthy barrier. The formula is fragranced with OUAI's Cape Town scent, a calming mix of spearmint, ginger, basil, and green fig, making daily application a pleasant ritual. It's presented in a 2 fl oz vial perfect for targeted use and easy inclusion in your routine.

How does this serum hydrate a dry scalp?

The serum uses hyaluronic acid to attract and hold moisture at the scalp surface, while lightweight oils help seal that hydration without weighing hair down. Together, the ingredients create a balanced environment that feels less tight and looks healthier.

• Hyaluronic acid delivers surface hydration and retains moisture.
• Lightweight carrier oils prevent residue and buildup.
• Adaptogens support scalp resilience against daily stressors.

Will this product work with my hair type and styling routine?

Yes — the serum is formulated for all hair types, from fine to coily, and won’t interfere with styling. It’s lightweight enough for daily use and designed to be applied directly to the scalp, avoiding heavy layering that can flatten styles.

• Suitable for fine, medium, and thick hair textures.
• Apply before or after styling depending on preference.
• Non-greasy finish preserves volume and texture.

How should I use the OUAI Scalp Serum for best results?

For targeted care, part hair and apply a few drops directly to the scalp, massaging gently to distribute. Use daily or as needed: small, consistent applications help maintain hydration and comfort without product buildup.

• Part hair and dispense drops onto scalp zones needing attention.
• Massage lightly for 10–20 seconds to encourage absorption.
• Can be used on damp or dry scalp; no rinse required.

What sensory experience can I expect from the Cape Town scent?

The Cape Town fragrance offers an earthy, calming aroma with green and herbal top notes that feel fresh but subtle. It’s formulated to be noticeable without overpowering, making each application a pleasant, mindful moment.

• Top notes: spearmint and ginger for freshness.
• Herbal heart: basil for an aromatic, grounding layer.
• Base: green fig introduces a soft, natural sweetness.

Who is this for: OUAI Scalp Serum is ideal for anyone seeking a simple, daily scalp treatment that merges skincare sensibility with haircare. If you want lightweight hydration, a soothing sensation at the root, and a formula that pairs well with all hair textures and your existing styling products, this serum fits into a practical routine without fuss.
