Short-Term Efficacy of Autologous Cellular Micrografts in Male and Female Androgenetic Alopecia: A Retrospective Cohort Study

The study on autologous cellular micrografts (ACM) for androgenetic alopecia (AGA) in 140 patients (113 females, 27 males) aged 18-65 demonstrated significant short-term improvements in hair density, thickness, and follicular unit count, particularly in the frontal region. Negative indicators like thin hair percentage and yellow dots decreased, and the mean hair-covered scalp area increased, providing notable cosmetic benefits. Two-thirds of patients showed favorable changes in cumulative hair thickness, and over 50% improved in other parameters. Despite the promising results, the retrospective and noncontrolled design limits the study's external validity, and longer follow-up is needed to confirm long-term efficacy.
