How Microneedling Works
Microneedling involves creating micro-injuries in the scalp using fine needles, which trigger the body’s wound-healing response. This releases growth factors that activate dormant follicles and improve blood flow. Studies confirm a significant increase in density when combined with topical minoxidil.
Clinical Evidence
A 2024 randomized trial published in the Journal of Cosmetic Dermatology showed that microneedling plus minoxidil led to 45% greater regrowth versus minoxidil alone after 24 weeks. It’s now a top in-office treatment for androgenetic alopecia.
Home vs. Clinical Treatments
At-home derma rollers (0.5 mm) can be used weekly, while in-clinic sessions use 1.5 mm devices for deeper stimulation. Always disinfect tools before use to prevent infection.
Safety Tips
Do not microneedle on inflamed or infected scalps. Avoid combining with strong actives immediately after treatment. Mild redness and flaking are normal for 24–48 hours.
Expert Opinion
Dr. Emily Hartman explains, “Microneedling increases topical absorption by up to 300%. When done correctly, it’s one of the most effective non-surgical regrowth methods.”
