Chances of losing hair?

[huehue]

Just wanted to get an idea of how my future would look like with hair loss. Moms side is completely bald free. Dad's side generally has hair like this. Dad's father/grandpa had same hairline as my dad does right now when he died at 93 or so. Clearly it isn't a perfect hairline. I just don't understand where is the line set with balding genetics? When is a family line considered to have MPB genes? I have included a few pics of my dads hairline in this thread. He is 55.

for a 55 year old man, he has a great head of hair!

Your kind of barking up the wrong tree in the sense that no one has any real answers to your questions. I mean he is like NW 2 or 3 it looks like so if you want a NW 2 or 3 then do nothing but its not as simple as your dad because you might not follow that exactly. Its largely unpredictable so if you start losing hair the best advice is just do something if you care. So it doesnt look too bad from what he has if you followed that.
