Do temples naturally have less hair

[PaulS94]

Is it ever normal for temples to have less hair than the rest of your head? Mine seem to be a lot "thinner" than anywhere else, but I think I remember them being like this even when I was a kid. The thinness goes really deep into my temples though, almost halfway into my head but there doesn't seem to be any miniaturization. (At least not any that I can see with my naked eye) it just looks like there is less hair there. Around 50% less... I've even plucked out countless hairs from both sides and they look the same as hairs from the sides, middle, and back of my head in terms of thickness and length.

I know it's hard to tell about without any pictures, but with my hair type it's near impossible to see what I'm talking about. Could this possibly be related to stress and diet? I'm only 19 and I've been stressing like crazy about my hair since I was 16 and I'm also severely underweight...(going to see a doctor about this today.)

My mom's side of the family has a really bad history of male pattern baldness...almost every male is completely bald, and they won't tell me when they started losing their hair because they think I'm just being paranoid. >_> My dad doesn't have any hair loss though and my hair is almost exactly like his, which is the complete opposite of my mom's.
