How bad is my hair? I'm 16.

[MHD]

All photos above were made when my hair was wet and pulled back as far as possible. I'm 16 and I'm wondering if I'm balding? Sometimes I see hair on my hands when I rub my head or see hair on desk, but not too much, usually 1 hair, but it happens many times. Funny when I try to pull my hair out I usually don't pull a single one. Left temple looks pretty bad to me and I think my hair on forehead is pretty thin. My dad is not bald, he however has these temples, he usually has short hair so it's more noticable but they are not big so he's not balding (at least not yet, 45). Dad's dad has all his hair. Mother's dad was party bald (at front) but he started at about age of 50 and at the age of 92 he still had hair, at least on top and back. I hope I was specific enough, my family is not bald, I've never seen any member of my family bald, I really hope I won't be the first one . Also I started eating healthier, and being more active (I'm skinny and tall but I don't really like sports). Can I do anything about my hair, should I worry? Also does whey protein cause hairloss? Just wondering because I read it somewhere.
