0.3 mm Derma Roller – Scalp & Hair Growth Support

Dr. Groot™ 0.3mm Derma Roller is a professional-grade microneedling tool designed specifically for the scalp. Used before applying hair serums or growth treatments, it creates micro-channels in the scalp skin that significantly increase the absorption and efficacy of active ingredients — so your hair products actually reach the follicle, not just the surface.

What it does: Microneedling at 0.3mm stimulates collagen production in the scalp, promotes increased blood flow to follicles, and supercharges the effectiveness of topical hair growth products like minoxidil, rosemary oil, or Dr. Groot™ serums.

• ✅ 0.3mm needle depth — effective for scalp use, no pain, no downtime
• ✅ 540 titanium micro-needles for precise, even coverage
• ✅ Increases serum absorption by up to 80%
• ✅ Stimulates natural scalp healing response and follicle activity
• ✅ Dermatologist-recommended technique for hair thinning and hair loss
• ✅ Reusable, hygienic, easy to clean

How to use: On clean, dry scalp, gently roll 3–4 times in each direction (horizontal, vertical, diagonal) over thinning areas. Apply your serum or growth treatment immediately after. Use 1–2x per week.

Best for: Men and women experiencing hair thinning, receding hairline, or reduced hair density who want to amplify the results of topical treatments.

Best used with the Dr. Groot™ Scalp Roll-On Serum or Scalp Relief Tonic for a clinical-grade at-home hair restoration protocol.
