Hair loss in males is not inherited from their fathers, it's inherited from their mothers, who inherit it from THEIR fathers. So look at your maternal grandfather, or your grandmother's father. (Or if your mother is balding, you're DEFINITELY going to go bald if you're male.) Even though if your grandfather or great-grandfather are balding, that doesn't mean you WILL go bald, it means you have a 50/50 chance of having inherited the genes for baldness.
