I am 30. I just started using finasteride 3 months ago, also started using Regaine two weeks ago.
My dad is 70 and still has a good bit of hair, not a totally full head but probably more than most 70 year olds. However my grandads were bald, but not until later in life, one grandad died at age 90 and he was bald enough at that stage, but I think he had a good bit of hair for most of his youth. My other grandad I think went bald younger, and he was proper bald. I have two brothers and they both have no hair loss at all, male cousins don't seem to have it and uncle has a fair share of hair at age 62. The baldness gene is definitely there and I seem to be the unfortuneate one in my fsmily thst has got it.
