In genetically susceptible men, dihydrotestosterone (DHT) can progressively shorten the hair growth cycle and contribute to follicle miniaturisation. Over time, affected hairs may become finer, shorter and less visible, often around the crown, mid-scalp or hairline.
Finasteride targets the DHT pathway.
Finasteride is a 5-alpha-reductase inhibitor. It reduces the conversion of testosterone to DHT, helping slow the process that drives androgenetic alopecia. With consistent use, some men maintain more existing hair and may experience increased growth. Response varies, and ongoing treatment is generally needed to maintain benefit.
Men who notice hair loss alongside low energy or reduced libido may benefit from reviewing our hormone therapy options.
