The Expressions of Androgen Receptors and Estrogen Receptors in Bald and Non-Bald Areas of Androgenic Alopecia

The study "The Expressions of Androgen Receptors and Estrogen Receptors in Bald and Non-bald Area of Androgenic Alopecia" conducted 21 years ago, aimed to evaluate the difference in the expressions of androgen receptors (AR) and estrogen receptors (ER) in bald and non-bald areas. The study involved 6 cases of androgenic alopecia and used immunohistochemical analysis on biopsy specimens from both areas. The results showed that androgen receptors were at a higher level in the bald area, while estrogen receptors showed no difference between the bald and non-bald areas. The study concluded that locally increased androgen activities may be related to hair loss in androgenic alopecia, and estrogens have less relationship in the pathogenesis of androgenic alopecia.
