Oral finasteride (1 mg Propecia/Proscar) is FDA-approved для male pattern hair loss с extensive long-term safety data. Topical finasteride (compounded — not FDA-approved as а standalone product) is gaining popularity as compounding pharmacies and telehealth services (Hims, Keeps) offer it. Topical efficacy: recent RCTs show comparable hair regrowth к oral 1 mg в the first 6 months, с possibly less sustained efficacy beyond year 1 (data sparse). Systemic absorption is roughly 1/40th of oral (still some, not zero — sexual side effects reported but lower rate). Cost: oral generic ~$5-15/month; topical compounded $25-50/month. Best candidate для topical: men с oral-related sexual side effects who want к continue treatment. First-line for most: oral.
