Hi doctor, I used oral finasteride for many years but never stop my MPB progress and give me hard side effects. So after stopping the drug, i started with topical finasteride and after 3 months it appears to me that there is regrowth and including the temples (a tough place to get results).
I believe that topical finasteride reduced much more topical DHT than oral, so that neither produces more sebum on the scalp. Why even prescribe oral finasteride giving serious side effects, if topical is much better?
In the United States, I am not aware of an FDA approved form of topical finasteride. If there was a topical form of this drug sold commercially, the FDA would have to review it for safety and effectiveness, which would likely take years before coming to market. Unless you’re buying a compounded topical lotion or shampoo from a licensed pharmacist, anyone today who is claiming to supply a topical finasteride is violating the FDA regulations and would be open to FDA sanctions or prosecution.
I don’t know what you’re using (brand or dosage), nor do I know of its safety or effectiveness. That said, the reason I prescribe oral finasteride as opposed to a topical is that the oral is a prescription drug that is available for sale in any pharmacy. I don’t know of any topical finasteride sold here. If you’re outside the US, the rules may be different… but I’m a US-based physician.
