July 2023 in “International journal of trichology” In this study, no significant association was found between the severity of androgenetic alopecia in males and trichoscopy features such as hair diameter diversity, vellus hair, and white dots, suggesting that trichoscopy may not predict alopecia severity based on the Hamilton–Norwood scale.
This study found that in men with androgenetic alopecia, nitric oxide synthase protein expression was significantly higher at androgenetic sites compared to non-androgenetic sites or those of healthy controls, suggesting a possible role in hair follicle regulation.
