Finasteride

Finasteride is the gold-standard prescription treatment for male-pattern hair loss (androgenetic alopecia). By blocking the enzyme 5-alpha reductase, finasteride reduces DHT levels by approximately 70%, effectively halting hair follicle miniaturization. Clinical studies show it stops hair loss progression in over 90% of men and promotes visible regrowth in 65% of patients within 12 months of consistent use.

At hi-doctor.ai, our EU-licensed doctors evaluate your hair loss pattern, medical history, and suitability for finasteride through a comprehensive online consultation. If appropriate, you receive your prescription within 24 hours with medication delivered discreetly to your door.

Finasteride works by selectively inhibiting Type II 5-alpha reductase, the enzyme responsible for converting testosterone into dihydrotestosterone (DHT) in the scalp. DHT is the primary hormone responsible for shrinking hair follicles in genetically susceptible men. By reducing scalp DHT levels by ~70%, finasteride allows miniaturized follicles to recover and resume producing thicker, longer hairs.

The standard dose is 1mg daily, taken orally. Results typically become noticeable after 3-6 months, with maximum benefit at 12-24 months. Finasteride must be taken continuously to maintain results.

Finasteride is generally well-tolerated. In clinical trials, side effects occurred in less than 4% of men and included: decreased libido (1.8%), erectile difficulty (1.3%), and decreased ejaculate volume (0.8%). These side effects are typically mild and reversible upon discontinuation. Our doctors discuss all potential risks during your consultation.
