Scalp Microneedling: Controlled Injury for Regeneration

Learn how tiny punctures stimulate growth factors that jumpstart new hair development.

Source: Dermatologic TherapyPublished on: December 20, 2024
Abstract in Plain English

Microneedling, a technique using fine needles to create controlled skin micro-injuries, has shown surprising potential for stimulating new hair growth. A 2024 randomized study in Dermatologic Therapy compared microneedling with and without topical Minoxidil.

Key Findings
  • Participants receiving both microneedling and Minoxidil showed a 3× higher regrowth rate.
  • The procedure increased collagen formation and activated growth factors like VEGF.
  • Minimal downtime and mild redness were reported as the only side effects.
  • Weekly treatments for three months maintained long-term density gains.
Why It Matters

Microneedling’s low cost and minimal risk make it an attractive adjunct to standard therapies. It triggers the body’s own regenerative response, bridging cosmetic and biological repair.

Study Limitations

Needle depth and pressure were not standardized across all practitioners.
