Does Microneedling Prevent Hair Loss

This was a topic GQ explored this week with Dr. Michele Green. While research on microneedling alone for hair loss is limited, studies suggest it can increase hair count—especially when combined with proven therapies like minoxidil or PRP. Dermatologists emphasize that microneedling works best as part of a broader, ongoing hair-loss plan rather than as a standalone option. Dr. Green says that you might experience minor redness, swelling, and pain, though side effects tend to be mild and short-lived. You might shed less overall, but at best, one can expect “modest to meaningful” improvements in fullness, shaft thickness, density, and overall hair health.

On its own, microneedling shows modest benefits, but research and dermatologists agree it works best as a complementary therapy. She notes that medical-grade hair loss therapies like oral Propecia are likely to be more effective. “However, scalp microneedling can work with other therapies—oral, topical, or in-office treatments—to prevent hair loss and promote hair regrowth,” she says.
