Finasteride is FDA-approved for male pattern hair loss in men only. It is not for use by women or children. Women who are or may become pregnant should not handle crushed or broken tablets due to the risk of birth defects in a male fetus. Prescribed following an individualized medical evaluation; individual results vary.

Oral Finasteride

Block DHT. Keep your hair.

/ month

The most clinically proven oral treatment for male pattern hair loss. Finasteride works by blocking the conversion of testosterone into DHT — the hormone responsible for shrinking hair follicles in genetically susceptible men. By lowering DHT at the scalp, it slows or stops hair loss and helps many men regrow hair, particularly at the crown and mid-scalp.

Taken as a single 1 mg tablet once daily, finasteride is FDA-approved for androgenetic alopecia in men and is most effective when started early. Results typically become visible after 3–6 months of consistent use.

Key Features

Targets the Root Cause: Inhibits the 5-alpha-reductase enzyme to lower DHT, the primary hormonal driver of male pattern hair loss.

Slows and Stops Loss: Highly effective at halting the progression of thinning, helping most men hold on to the hair they have.

Regrows Hair: Many men see measurable regrowth at the crown and mid-scalp with continued daily use.

Clinically Proven: One of only two FDA-approved treatments for male pattern hair loss, backed by decades of clinical data.

Once-Daily Pill: A single small tablet a day — simple to take and easy to stay consistent with.

Works Even Better Combined: Frequently paired with minoxidil to address both the hormonal cause and follicle stimulation for stronger results.

FAQs

Common questions, answered.

How does finasteride work?

Finasteride blocks the enzyme 5-alpha-reductase, which converts testosterone into DHT — the hormone that shrinks hair follicles in men with genetic hair loss. By lowering DHT at the scalp, finasteride slows or stops hair loss and helps many men regrow hair.

What are the side effects of finasteride?

Most men tolerate finasteride well. The most reported side effects are sexual — decreased libido, erectile difficulties, or reduced ejaculate — and occur in a small percentage of users. These usually resolve if the medication is stopped, though a small number of men report persistent effects. Tell your clinician about any mood changes or breast tenderness.

How long until finasteride works?

Finasteride works gradually. Most men need at least 3 months of daily use before seeing benefit, with fuller results around 6–12 months. Continued daily use is required to maintain results.

Can women take finasteride?

Finasteride is approved for men only. Women who are or may become pregnant should not take it or even handle crushed or broken tablets, because it can cause birth defects in a male fetus. EOS Health prescribes oral finasteride for men.

Can I combine finasteride with minoxidil?

Yes. Finasteride and minoxidil are the two most proven hair-loss treatments and work through different mechanisms, so combining them often delivers better results than either alone. Your clinician can design a combined regimen that fits your needs.
