Scalp Neuropathy in Androgenetic Alopecia

The study explored the potential role of scalp neuropathy in androgenetic alopecia (AGA) by evaluating scalp sensation in 62 men, divided into non-AGA and AGA groups. The research found a significant association between neuropathy at the vertex and frontotemporal regions of the scalp and AGA. Specifically, 48% of men with AGA showed neuropathy at the vertex compared to 13% without AGA, and 63% of men with AGA displayed neuropathy at the right frontotemporal recess compared to 20% without AGA. The study suggested that scalp neuropathy might manifest as autonomic and peripheral neuropathy, potentially affecting the arrector pili muscle. However, the study was limited by its small sample size and showed association rather than causation. Further research with larger cohorts was recommended to validate these findings.
