Is Hair Usually Thinner Around the Temples?

I am a 21 year old male and have noticed that if pick up my hair around the temple regions of my head, more scalp is visible than if i do it nearer the middle of my head. I dont seem to have a receeding hairline (maybe developing a mature hairline though). However i have noticed that many girls and young children have the same sort of idea on their head (scalp more visible around temple areas if hair is standing up) So my question is, Is the scalp generally more visible aroud the temple than it is in the middle of your head for example? Thank you.

The hair density above the ears is often less than the density elsewhere (like that of the back of your head). When people develop Diffuse Unpatterned Alopecia (DUPA), it is often seen first in the sides above the ears because the density there is as much as 30-60% less than in the scalp elsewhere. The answer to your questions is to have your hair mapped out for miniaturization, and if you have genetic balding or DUPA, it will clearly show up.
