Is there anyone with absolutely awful hair genetics (family members/relatives with NW7 in their 20s) that succeeded with finasteride?

I'm curious if anyone has maintained a full head of hair on finasteride despite the deck being completely stacked against them genetically.

I'm losing ground on fin, and both of my uncles (on my mom's side) and my grandpa had full on NW7s in their mid 20s. Dad's side is all bald as well, but not to that extent. I can tell I have very strong balding genes, I'm curious if there's anyone that should be slick bald right now is walking around with a full head of hair because of fin.
