Genetics dictate how hair follicles respond to circulating hormones. In men predisposed to androgenetic alopecia, hair follicles along the temples, hairline, and crown possess androgen receptors that are hyper-sensitive to dihydrotestosterone (DHT). Over successive growth cycles, DHT binds to these receptors and causes follicular miniaturization. The growth phase shortens. The hair shaft thins, weakens, and eventually stops piercing the epidermal surface.

Finasteride alters this cascade at the molecular level. It is a competitive, specific inhibitor of Type II 5-alpha reductase, the intracellular enzyme responsible for converting free testosterone into DHT. A standard oral finasteride dosage of 1 mg daily suppresses serum DHT concentrations by approximately 65% to 70%, while lowering scalp DHT concentrations by more than 60%.

Follicles rescued from androgenic pressure can resume normal anagen cycles. Clinical trials spanning two decades indicate that finasteride halts progressive recession in roughly 83% to 90% of men over a five-year period. Significant regrowth occurs in approximately 65% of patients. It does not create new follicles out of scar tissue; it revitalizes struggling, miniaturized roots.
