ACT+ ACRE Microbiome Cooling Scalp Serum — 2.2 fl oz | Peppermint Menthol Relief, Amino M3 Complex for Itchy, Flaky Scalp

Act+Acre Microbiome Cooling Scalp Serum is a leave-on treatment that calms itching and visibly reduces loose dandruff while supporting a balanced scalp microbiome.

This concentrated daily serum blends cooling menthol with a targeted Amino M3 Complex and botanical pre- and post-biotics to help restore scalp comfort and reduce visible flakes. Designed for all hair textures — straight, wavy, curly, and coily — it’s cold-processed to preserve active potency and formulated without sulfates, parabens, silicones, or synthetic fragrances.

How quickly will I feel relief from scalp itch?

Cooling ingredients like menthol and menthyl lactate provide immediate soothing sensation on contact, so most users feel relief after the first application. Relief is topical and temporary; continued daily use helps maintain comfort.

• Instant cooling on application for prompt itch reduction
• Use 2–3 pipettes directly on clean or dry scalp
• No rinse required — lightweight, non-greasy finish

Can this reduce visible dandruff and flakes?

Clinical testing of the Amino M3 Complex showed a meaningful decrease in adherent dandruff appearance after regular use, with measurable results at 30 days. The formula combines microbiome-supporting ingredients to improve scalp environment, which can reduce recurring flake visibility over time.

• Clinical study reported 52% reduction in adherent dandruff appearance at Day 30
• Contains prebiotics, postbiotics and amino acid lipids to support balance
• Suitable for ongoing spot treatment and daily maintenance

How do I incorporate this into my routine without weighing hair down?

Apply directly to the scalp in small amounts and massage gently; the serum is formulated to absorb without leaving heavy residue. It’s intended as a leave-in treatment so you can use it before styling or between washes for targeted relief.

• Apply 2–3 pipettes to clean scalp, massage, then style as usual
• Safe as a spot treatment on dry hair where needed
• Cold-processed formula preserves actives while staying lightweight

Who is this for? This serum is made for anyone experiencing dry, itchy scalp and visible loose flakes who prefers plant-based, cruelty-free care.
