The Relation Between Androgenetic Thin Hair Diagnosed by Trichoscope and Benign Prostatic Hyperplasia

The study, conducted on 100 males (50 with androgenetic alopecia (AGA) and 50 controls), found a significant correlation between hair diameter in AGA diagnosed by trichoscopy and the presence of benign prostatic hyperplasia (BPH). Patients with AGA who had thin hair (<0.03 mm) showed significant differences in age, dihydrotestosterone level, testosterone level, and urinary symptoms compared to those with thicker hair (>0.03 mm). The findings suggest that individuals with AGA and thinner hair may be more susceptible to prostatic enlargement and related symptoms, and that trichoscopy can be used to diagnose the severity of AGA alongside the Hamilton-Norwood scale. The study indicates the need for further research on the effects of 5-alpha reductase inhibitors on both AGA and prostatic volume and poses the question of whether early AGA treatment could mitigate the risk of developing BPH.
