Hair Loss Treatments: Finasteride vs Minoxidil — Which Is Right for You?
How finasteride works
Finasteride is a prescription-only tablet taken once daily. It works by blocking the conversion of testosterone into dihydrotestosterone (DHT), the hormone responsible for shrinking hair follicles in men with hereditary hair loss. By reducing DHT levels, finasteride slows further hair loss and, in many cases, promotes regrowth.
Clinical trials have shown that around 86% of men who take finasteride daily either maintain their existing hair or experience regrowth, particularly in the crown area. It typically takes three to six months of daily use before visible results appear, and continued use is required to maintain the benefits.
How minoxidil works
Minoxidil (sold under the brand name Regaine) is a topical treatment applied directly to the scalp. It's available without a prescription as a foam or liquid solution. Minoxidil works by increasing blood flow to the hair follicles, which may stimulate dormant follicles and promote regrowth.
Results vary between individuals, and like finasteride, minoxidil requires consistent daily use for at least three to four months before improvements become visible. Stopping treatment typically results in hair loss resuming within a few months.
Key differences at a glance
Finasteride: Oral tablet, prescription-only, once daily, targets the hormonal cause of hair loss (DHT), most effective for crown and mid-scalp thinning
Minoxidil: Topical application, available without prescription, applied once or twice daily, increases blood flow to follicles, effective for crown thinning
Can you use both together?
Yes. Many clinicians recommend using finasteride and minoxidil together for a combined approach — finasteride tackles the underlying hormonal cause while minoxidil stimulates follicle activity directly. This combination is often considered the most effective non-surgical approach to treating male pattern hair loss.
Side effects to be aware of
Finasteride side effects are uncommon but can include reduced libido, erectile difficulties, or mood changes in a small number of men. These usually resolve after stopping the medication. Minoxidil can cause scalp irritation, dryness, and some initial shedding (which is usually temporary and a sign that dormant follicles are being stimulated).
Which is right for you?
If your hair loss is recent and primarily at the crown, either treatment may help. If it's more advanced or you want to target the hormonal root cause, finasteride (alone or combined with minoxidil) may give you the best results. Our clinicians can help you decide based on your individual pattern and preferences.
