When you have aggressive hair loss, Finasteride is like the first step of a long set of stairs that you will climb. Either you will keep climbing, or fall off, no other option.
I was on Finasteride for one year. I kept losing my hair, and grew some puffy nipples along with it. Later on I started using Alpicort which helped me regrow everything that I lost but I couldn't keep using it due to estrogenic side effects. After that I switched to RU58841 which has much fewer side effects than Finasteride and is very close to maintaining but not quite, so I keep very slowly losing hair but at 1/5th of the pace that I did on Finasteride. The next logical step is to bump up the topical regimen, so now I am moving to experimental anti-androgens and those are going to be enzalutamide and darolutamide.
Also during this whole time I keep using Minoxidil. I recently added the dermastamp as well. I used Ketoconazole for a year but found it to be totally worthless.
Bottom line is as I said, if giving up is not an option, and you are not afraid of experimenting with things that are untested and potentially unsafe, there is always something next to try...
