Does adding microneedling (tiny skin punctures) to minoxidil help it work better than minoxidil used alone?

Adding microneedling (at-home or in-clinic) to minoxidil appears to meaningfully boost hair regrowth beyond minoxidil alone, with only a modest increase in mild irritation risk -- a reasonable, low-cost add-on for people already using minoxidil.

What they did

Pooled 12 randomized controlled trials comparing minoxidil plus microneedling against minoxidil alone in people with androgenetic alopecia, examining hair count, hair diameter, and doctor-rated improvement.

What they found

Combined therapy significantly improved hair count (standardized mean difference 1.32) and hair diameter (SMD 0.34) compared with minoxidil alone. Doctors' visual assessments favored the combination about 5 times more often (odds ratio 5.01). Needle depth, treatment duration, and device type did not substantially change outcomes. Mild, self-limiting side effects were somewhat more common with the combination (74 vs 59 events) but none were serious.

Limitations

Nearly all participants were Asian, Middle Eastern, or North African, so it is unclear whether results generalize to other populations (including typical Western or mixed-ancestry groups); could not analyze results by age; substantial heterogeneity in microneedling schedules across studies.
