This article is educational only. It is not medical advice, and I am not a doctor. Minoxidil and finasteride are medicines with side effects and situations where they should not be used. Talk to a doctor or pharmacist before starting or stopping either one. See our Editorial Policy for how we research and update our articles.
“What should I do about my hair loss?” hides three different questions: do you want to slow the loss, thicken hair that is thinning but still there, or add hair where there is none left? Minoxidil, finasteride and a transplant each answer a different one.
What each one does
Minoxidil works directly on the hair follicles that are still alive, helping them grow. It does not act on the hormonal cause of pattern hair loss. According to Mayo Clinic, over-the-counter minoxidil comes as a liquid, foam or shampoo and works best applied once a day for women and twice a day for men.
Finasteride is a prescription pill that lowers DHT, the hormone that drives pattern hair loss in men who are genetically prone to it. Mayo Clinic describes it as a prescription drug for men and says many men taking it see their hair loss slow, and some see new growth.
A hair transplant does not treat the cause at all. It moves follicles that are resistant to DHT from the back and sides of the head to thinning or bald areas, as explained in our FUE vs FUT guide. It is the only one of the three that adds hair where no working follicles remain.
How well they work
- Minoxidil: Mayo Clinic says it takes at least six months to prevent further loss and start regrowth, and that you need to keep using it to keep the benefit.
- Finasteride: it may take a few months to tell whether it is working, and Mayo Clinic notes it may not work as well for men over 60.
- Together: hair restoration surgeon Dr. Jeff Donovan writes that finasteride is much more effective than minoxidil for male pattern hair loss, and that adding minoxidil gives a slightly better result than finasteride alone. Because they work in different ways, many doctors use them together.
Results vary from person to person, and studies measure “success” in different ways (stopping loss, visible regrowth or patient satisfaction), so be wary of any single percentage presented as a promise.
Side effects to discuss with a doctor
Minoxidil is applied to the scalp. Mayo Clinic lists scalp irritation and unwanted hair growth on nearby skin of the face and hands as possible side effects.
Finasteride acts on hormones throughout the body. Mayo Clinic lists rare side effects including reduced sex drive and sexual function and an increased risk of prostate cancer. In 2022, as reported by Reuters, the US Food and Drug Administration required finasteride labels to add suicidal ideation and behavior to the listed adverse reactions, while declining a petition to remove the drug from the market. Women who are or may be pregnant should not handle crushed or broken tablets.
Weighing these risks is a conversation for you and a doctor, not something to decide from an article. If you notice sexual side effects, low mood or anything else that worries you after starting finasteride, contact the prescriber rather than waiting it out.
Where a transplant fits
Medication can only work on follicles that are still alive. Once an area is completely bald, there is nothing left for minoxidil or finasteride to act on. Our PRP vs transplant comparison makes the same point: non-surgical treatments manage the hair you have, surgery adds hair where it is gone.
For people with established baldness, the options are not really competitors; they work in sequence. Mayo Clinic notes that hereditary hair loss will eventually progress despite surgery. That is why many surgeons recommend continuing medication after a transplant: not for the transplanted hair, which is generally resistant, but for the native hair around it. Skipping this is a common reason people feel a transplant “stopped working” years later, as we explain in our is it worth it and regret guides.
A rough way to think about it
- Early thinning, nothing completely bald yet: medication is the usual starting point, chosen with a doctor. It is cheap enough to try before any permanent decision, and it buys time to see how your hair loss develops (see our guide to transplants at a young age).
- Confirmed male pattern hair loss and you want the strongest non-surgical option: finasteride, often with minoxidil, after discussing the side effects first.
- Areas that are already bald: this is where a transplant becomes relevant, usually alongside medication for the surrounding hair.
- Already on medication and considering surgery: you usually do not have to choose. The common path is medication, surgery for what medication cannot reach, and medication afterwards.
Cost over time
Minoxidil and finasteride are ongoing costs for as long as you want the benefit; Mayo Clinic notes that stopping minoxidil means the benefit is likely to fade. A transplant is a large one-off cost for the treated area (see our cost by country guide), but most surgeons still recommend ongoing medication. Which is cheaper depends on your time frame.
Frequently asked questions
Can women take finasteride? That is a question for a doctor. Mayo Clinic describes it as a drug for men, and it must be avoided in pregnancy. Women’s hair loss is assessed differently, as our female hair transplant guide explains.
Do I have to use them forever? Generally, the benefit lasts only while you keep using them.
Can I stop medication after a transplant? Not automatically. Surgeons often recommend continuing it to protect the native hair around the grafts.
Are there newer treatments? Other medicines, such as oral treatments prescribed off-label, are used by some doctors. Check any claim about a new treatment against a medical source and discuss it with a doctor before acting on it.
