ACT+ ACRE Stem Cell Scalp Serum 2.2 fl oz — Cold-Processed, Vegan Lightweight Leave-In Treatment

ACT+ ACRE Cold Processed Stem Cell Scalp Serum is a lightweight, leave-in scalp treatment formulated with apple stem cells, bamboo extract and aloe to help strengthen hair, hydrate the scalp and reduce visible shedding.

This concentrated 2.2 fl oz serum is cold processed to preserve delicate actives and designed for daily use on clean, damp or dry scalps. The formula combines botanical stem cells, sodium hyaluronate and plant extracts to support the scalp environment that hair follicles rely on, while remaining vegan, color safe and free from sulfates, silicones, parabens and synthetic fragrances.

How should I use this serum for best results?

Apply the serum directly to the scalp once daily, using 1–2 pipettes to target thinning areas. Massage gently to distribute the product, then leave it in—no rinse required. Consistent use helps maintain hydration and keeps active ingredients working between washes.

• Use on clean, damp or dry scalp.
• Apply 1–2 pipettes per session, focusing on thinning zones.
• Massage until absorbed; do not rinse.
• Daily application recommended for sustained support.

What are the key ingredients and what do they do?

The serum blends apple stem cells to support the scalp environment, bamboo extract for strengthening minerals, and sodium hyaluronate plus aloe vera for targeted hydration. These ingredients were included to help fortify hair strands and improve scalp moisture balance without weighing hair down.

• Apple stem cells — botanical support for scalp health.
• Bamboo extract — silica-rich botanical to help strengthen strands.
• Sodium hyaluronate & aloe — lightweight hydration for the scalp.
• Cold-processed formulation preserves active potency.

Is this serum safe for color-treated or sensitive scalps?

Yes—this formula is color safe and free from common irritants like sulfates, parabens, silicones, phthalates and synthetic fragrance. It’s trichologist formulated and designed to be gentle, though patch testing is recommended for very reactive skin.

• Color-safe for chemically treated hair.
• Free from sulfates, silicones and parabens.
• Vegan and gluten free.
• Patch test first if you have high sensitivity.

When will I notice changes in shedding or fullness?

Individual results vary, but consistent daily use provides the environment needed for observable changes over weeks. Clinical feedback in study settings suggests users often notice differences within a few months, while many continue regular use to maintain improved scalp condition.

• Daily application encourages gradual improvement.
• Visible changes typically reported after several weeks to months.
• Combine with a balanced routine for best maintenance.
