Is the old adage true? Everything I have read suggests that your mother's father's hairline (or lack of one) is the firmest indicator of where you'll be. Isn't it unfortunate that the only male relative in my family who ever had noticeable hair loss was my mom's dad. No one else in my family had it. My dad is 81 and still has kept most of his hair. So I just wonder does that mean I will end up like him? My older brother is not bald and he is 50, but I am in my mid 30s , and I am noticing some thinning here and there. Its just not a good feeling. Does that mean I am doomed to be like my grandfather- just that one guy ?
