Value of Hormonal Levels in Patients with Male Androgenetic Alopecia Treated with Finasteride: Better Response in Patients Under 26 Years Old

This study found that patients with male androgenetic alopecia who were 26 years old or younger had a better response to treatment with finasteride, with significant differences in hormone levels and improvement in alopecia. Specifically, higher levels of 5α-DHT at baseline were associated with better response to treatment in this age group. Patients over 26 years old had a slower improvement in alopecia and did not show significant changes in hormone levels during treatment. The study also found that the levels of PSA decreased during treatment in both age groups.
