Objective: In this study, the safety and efficacy of scalp repair serum microneedles combined with oral drug administration and topical medication were investigated for the treatment of moderate to severe androgenetic alopecia. Methods: Twenty patients, consisting of 4 males and 16 females, who sought treatment for moderate to severe androgenetic alopecia at our hair medicine research center alopecia specialty clinic between August and December 2022 were randomly selected for the study. Male patients underwent oral administration of finasteride topical application of 5% minoxidil, and biweekly scalp repair serum microneedle therapy. Female patients were administered spironolactone or Diane‐35 orally and applied 2% minoxidil topically, paired with biweekly scalp repair serum microneedle therapy sessions. After seven treatments, the scalp repair serum microneedle was discontinued, but oral administration and topical applications were continued, followed by a 1‐month follow‐up. Using a hair dermoscopy, hair follicles in a fixed region on the top of the head were manually counted per unit area to evaluate the hair restoration status of the patients quantitatively. Results: All 20 patients completed 3 months of combined therapy and a 1‐month follow‐up. On average, the patients experienced an increase of 42.6 hairs, with an efficiency rate of 100%. Significant differences were observed in hair count between any two of the first seven treatments (p < 0.001). A significant negative correlation was discovered between the initial pre‐treatment hair count and the total improvement of hair (p < 0.001), indicating that the greater the degree of hair loss before treatment, the more pronounced the improvement. Conclusion: Scalp repair serum microneedle combined therapy in moderate to severe androgenetic alopecia significantly reduces the number of microneedle treatments required, enhances treatment efficacy, and improves therapeutic outcomes.
