Who do I blame for my hair loss?

So I am looking in the mirror right now and my hair line is receding!!!! I am 21 and to young to be losing my hair. I haven't been this sad/angry in a long time. Someone tell me which one of my parents is responsible for this? Is it the father who determines his son's hair gene's or my mom. I need to know which parent is F*&%$#@ responsible for this!
