結論

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
