(18) balding or just mature hairline?

[nobodyimportantatall]

Been noticing somewhat of a recession happening in typical fashion from what I've seen in pictures and videos, just wondering if I should be concerned? I think I'm a Norwood 2 but i am somewhat of a hypochondriac about most things. My scalp hair also feels thinner compared to my back and sides, and you can also just about make that out in the picture (if it actually uploaded correctly)

Also i read that male pattern baldness actually comes from your grandfather on your mother's side instead of your actual father, is this true? My dad is bald and said his got bad at 19, but I've never met my grandparents on my mother's side for reasons I'm not explaining to strangers on the internet, i also asked my mother and she isn't sure if he is bald or not.

Thanks,

-A
