Maybe… but also maybe not. Both male pattern and female pattern hair loss does tend to run in families, but there is nothing specific about your mother’s father’s hair pattern in either case. While we are a mixture of both our mother and fathers DNA, we are not exactly 50/50 which is why sometimes we look more like our mothers or our fathers. For those who take after one parent more than the other, it is more likely they will share that parent’s side of the family for hair loss genetics.
