A
The Bottom Line
Microneedling has strong evidence for supporting hair regrowth in alopecia areata, especially when combined with topical medications, and is backed by multiple randomized controlled trials.
- 25 out of 32 studies show positive effects, with 9 RCTs providing robust evidence
- Works by creating micro-injuries that stimulate healing responses and improve drug absorption
- Most effective when combined with topical agents like corticosteroids or vitamin D3
- Both professional clinical procedures and at-home derma rollers have been studied
