In short: topical finasteride is finasteride applied to the scalp as a spray or solution, often mixed with minoxidil. In trials it worked about as well as tablets for male pattern baldness, while lowering DHT in the blood less. That may mean fewer side effects throughout the body, but it isn't side-effect-free, and long-term data is still limited. It's a prescription medicine.
How it differs from the tablet
| Finasteride tablet (1 mg) | Topical finasteride | |
|---|---|---|
| How it's taken | Swallowed once a day | Applied to the scalp, usually once a day |
| Effect on blood DHT | Lowers it a lot (about two-thirds) | Lowers it much less |
| Evidence for hair | Strong, long-term | Good short-term trials; less long-term data |
| Side effects | Small risk of sexual and mood effects | Probably lower risk, but not zero; scalp irritation possible |
| Availability in India (Oct 2026) | Widely available generics, from ≈ ₹45 a month | Only combined with minoxidil; we found no finasteride-only spray sold by Indian pharmacies |
Does it work?
A large trial of a 0.25% finasteride spray found it improved hair counts about as much as the tablet over 24 weeks, with a much smaller drop in blood DHT. It has since been approved in several European countries.
In India, topical finasteride is sold almost entirely as minoxidil + finasteride combination solutions (typically 5% + 0.1%), from about ₹230–1,000 for 60 ml. A finasteride-only spray like the one in the European trial wasn't available from Indian pharmacies when we checked in October 2026. Evidence for the combination solutions comes mostly from smaller studies. → Minoxidil + finasteride solutions
Who might choose it
- Men who want finasteride's benefit but are worried about side effects.
- Men who had side effects on tablets (discuss with your doctor first).
- Men already using minoxidil who want one combined application.
Not for women who are or could become pregnant, or for children, the same as the tablet. Keep it away from partners and children, and wash your hands after applying it.
How to use it
(Follow the product label and your doctor.)
- Apply to a dry scalp over the thinning areas, usually once a day. Don't use more than prescribed.
- Wash your hands afterwards. Let it dry before contact with a partner, children or pillows.
- Expect the same timeline as other treatments: judge results at 6–12 months.
Side effects
- Scalp: itching, redness, dryness (often from the alcohol or propylene glycol base).
- Body-wide: sexual or mood side effects are possible but appear less common than with tablets. Report any change to your doctor. → Finasteride side effects
FAQs
Topical or oral: which is better? For effect, they're broadly similar in short-term trials. Tablets have far more long-term data. Topical may suit men who are concerned about side effects. Decide with your dermatologist.
Can I mix finasteride tablets into my minoxidil? No. Home-made mixes give unknown strengths, and crushed tablets are a risk to pregnant women.
Do I need a prescription? Yes. Finasteride in any form is a prescription medicine.
See a doctor soon if you have: round bald patches that appear suddenly · hair coming out in clumps · redness, pain, pus, scaling or scarring on the scalp · hair loss with fever, weight loss, irregular periods, acne or new facial hair · eyebrow or eyelash loss · hair loss in a child.
