Hair Number per Follicular Unit as a Marker of Treatment Response to Combined Autologous Scalp‐Derived Micrografts and Allogeneic <scp>SHED</scp> ‐ <scp>CM</scp> in Male Androgenetic Alopecia

The study evaluated the efficacy and safety of a combined treatment using autologous scalp-derived micrografts (MG) and allogeneic dental pulp stem cell-derived conditioned medium (SHED-CM) in 59 patients with male androgenetic alopecia (MAGA). The treatment achieved a 69.5% response rate without serious adverse events, though 33.9% of patients experienced mild, self-limited injection-site pain and petechiae. Responders showed increases in hair diameter and hair number per follicular unit (HN/FU), which was a key marker distinguishing them from non-responders. The study concluded that the combined treatment was well-tolerated and led to significant improvements, with changes in HN/FU serving as a practical marker for assessing treatment response.
