Randomized trial of microneedling combined with 2% minoxidil topical solution for the treatment of female pattern hair loss in a Chinese population.

OBJECTIVE: To evaluate the efficacy and safety of 2% minoxidil combined with microneedling in the treatment of female pattern hair loss. METHODS: Forty female patients with female pattern hair loss were randomly divided into two groups with 20 patients each. The control group was treated with 2% minoxidil. The combined treatment group was treated with weekly microneedling in addition to daily minoxidil. The treatment period of both groups was 24 weeks. RESULTS: There were no significant differences in age or duration of disease between the two groups of patients. The effective rate in the combined treatment group was 85%, which was significantly higher than that of the control group (45%). The hair counts were also higher in the combined treatment group. All of the adverse reactions observed during the treatment period were mild. No severe adverse event was observed in either group. CONCLUSION: Microneedling combined with minoxidil had better efficacy for female pattern hair loss during the treatment period and follow-up. Microneedling combined with minoxidil therapy was safe and effective.
