Taking finasteride & hair transplant

26 y.o., I’m Norwood 2~3 with slight vertex loss. I’ve been on Fin for nearly 4 years and, as far as I can tell, it completely halted my hair loss. I don’t think I grew back any hair and it didn’t do a thing for my shedding for some reason, which I still have heaps, and I still have some miniaturized hairs along the hairline and vertex. But my hair seems to be in the same place as it was when I started taking the pill.

So I was thinking I’d maybe get a transplant eventually to get my hairline back to where it was, but there’s one thing concerning me: what if Fin suddenly starts losing effectiveness and my thinning resumes? Is that something that happens and have to keep in mind? Or even if it’s still receding at a very slow rate that I can’t really tell. I’m not sure I want to keep paying for further expensive transplants to play catch with my hairline.

Is there even a way to tell that it’s “safe” that your hair loss will surely be perfectly stable to get a permanent fix?

Finasteride continues to work, at least in slowing down the hair loss in most men. When getting a hair transplant, taking finasteride will prevent shock loss so you should continue to take it even after the hair transplant, possibly for your lifetime.
