my dads old. hes in his 60's, he has thin hair and doesn't have much hair top of his head. in older family photos he had hair when he was in his 30s and 40s. I'm trying to figure out how prone i am to hairloss, and since he is older i'm not sure if his age is a factor. My question is, is old age a factor for losing hair, or does it have to do with genetic male pattern baldness?
