My dad side of the family everyone was bald. But on my mother side everyone still has hair. Compared to my 2 brothers my hair is thick, long, and it grows fast. My dad told me when he was a kid he always had thin hair he told me I probably won't go bald. But how do I know I am safe? Is there any sings? Warnings? I am 17 right now and my hair is really long with no sings of balding.
