Finasteride vs. Rogaine
See how Finasteride and Rogaine compare on approved uses, dosing, side effects, and cost.
Key Takeaways
Finasteride is a daily oral tablet that lowers DHT, the hormone linked to hair follicle shrinkage in male pattern baldness.
Rogaine (minoxidil) is a topical treatment applied directly to the scalp and is available over the counter for both men and women.
The two drugs work through completely different mechanisms and are sometimes used together for a stronger combined effect on hair regrowth.
Finasteride vs. Rogaine Drug Summary
Finasteride
Finasteride is a 5-alpha-reductase inhibitor that blocks the conversion of testosterone into DHT, the hormone that shrinks hair follicles in male pattern baldness. It is taken as a 1 mg tablet once daily for hair loss, and requires a prescription. A 5 mg version (Proscar) is also FDA-approved for enlarged prostate.
Rogaine
Rogaine (minoxidil) is a topical vasodilator that widens blood vessels in the scalp to improve blood flow and stimulate hair follicles. It is applied directly to the scalp as a solution or foam, once or twice daily, and is available without a prescription. It is FDA-approved for both men and women.

Finasteride vs. Rogaine Indications
Finasteride
Finasteride is FDA-approved for male pattern hair loss and for symptomatic benign prostatic hyperplasia in men with an enlarged prostate. It is sometimes used off-label for hirsutism in women with hyperandrogenism, though it is not approved for use in women.
Male pattern hair loss (androgenetic alopecia)
Benign prostatic hyperplasia (BPH)
Off-label: hirsutism in women with hyperandrogenism
Rogaine
Rogaine is FDA-approved to regrow hair on the vertex of the scalp in men and on the top of the scalp in women with hereditary hair loss. It is also used off-label for beard growth, eyebrow growth, and alopecia areata.
Male pattern hair loss (vertex/crown)
Female pattern hair loss (top of scalp)
Off-label: beard and eyebrow growth
Finasteride vs. Rogaine Pros and Cons
Finasteride
Finasteride works systemically by lowering DHT levels throughout the body, which can slow hair loss at its hormonal source. It requires a prescription and ongoing monitoring, and carries a small but real risk of sexual side effects that some men report continuing after stopping the drug.
Pros
Convenient once-daily pill, no scalp application needed
Targets the underlying hormonal cause of male pattern baldness
Also FDA-approved to treat enlarged prostate (BPH)
Affordable prescription cost, often $10 to $50 per month
Cons
Requires a prescription and doctor follow-up
Not approved for use in women
Sexual side effects may persist after stopping the drug
Can lower PSA levels, complicating prostate cancer screening
Rogaine
Rogaine acts locally on the scalp to improve blood flow and stimulate follicles, without affecting hormone levels elsewhere in the body. It is available without a prescription and approved for both men and women, but it must be applied consistently and only works on certain areas of the scalp.
Pros
Available over the counter, no prescription needed
FDA-approved for both men and women
Comes in foam or liquid solution to fit preference
Foam version lowers risk of skin irritation from propylene glycol
Cons
Requires application once or twice daily to the scalp
Only approved for the vertex or top of the scalp, not a receding hairline
Can cause unwanted hair growth on the face or body
New hair loss and shedding often occurs if treatment is stopped
