Propecia vs. Rogaine
See how Propecia and Rogaine compare on approved uses, dosing, side effects, and cost.
Key Takeaways
Propecia is a daily pill that blocks the hormone behind hair loss, while Rogaine is a topical solution or foam that stimulates regrowth directly at the scalp.
Propecia is approved only for men, but Rogaine has versions approved for both men and women.
Some people use both together, since they work through different mechanisms and are not interchangeable.

Propecia vs. Rogaine Indications
Propecia
Propecia is FDA-approved to treat male pattern hair loss, also called androgenetic alopecia, in men only. It works by lowering levels of a hormone that shrinks hair follicles over time, which can slow further thinning and, in some cases, regrow hair.
Approved only for men with male pattern hair loss
Taken as a daily 1 mg tablet
Not approved for women or children
Works on the hormonal cause of hair thinning
Rogaine
Rogaine is FDA-approved to regrow hair on the top of the scalp in men with hereditary hair loss and in women with female pattern hair loss. It is applied directly to thinning areas and is also used off-label for beard or eyebrow growth and some cases of alopecia areata.
Approved for both men and women
Targets hair regrowth at the vertex or top of scalp
Applied as a liquid solution or foam
Off-label uses include beard and eyebrow growth
Propecia vs. Rogaine Pros and Cons
Propecia
Propecia works from the inside by targeting the hormone responsible for pattern hair loss, which makes it convenient but requires a prescription. Its main tradeoffs are sexual side effects in a small percentage of users and a higher out-of-pocket cost than over-the-counter options.
Pros
Simple once-daily pill, no scalp application needed
Treats the underlying hormonal cause of hair loss
Long track record since 1997 approval
May slow hair loss progression, not just regrow existing hair
Cons
Requires a prescription
Not approved for women
Carries risk of sexual side effects like decreased libido and erectile dysfunction
Roughly $100 to $250 per month without insurance, before savings programs
Rogaine
Rogaine works locally at the scalp to stimulate regrowth, which avoids systemic hormonal effects but requires consistent daily application. It is available over the counter and costs less, though it can cause local skin irritation and unwanted hair growth elsewhere.
Pros
Available over the counter, no prescription needed
Approved for use in both men and women
No systemic hormonal side effects
Roughly $15 to $50 per month without insurance, before savings programs
Cons
Requires twice-daily application for the solution
Can cause scalp irritation or contact dermatitis
May cause unwanted facial or body hair growth
Hair loss often resumes if application stops
