Hair Transplant Into a Thinning Area?

Hello doctor. I wanted to know if you have to lose all your hair first in a certain area before u can get a transplant or can you transplant hairs in an area that has vellus or thin hairs still there, but wouldn’t there be shock loss?

Take care

There could be shock loss if you’re not taking finasteride first, but that is the risk one takes when having a hair transplant in a thinning area. Transplanting in a completely bald area obviously won’t have the same risk factors, because there’s no existing hair to succumb to shock loss.
