My Head Got Bigger?

hi there.
im a 17 year old boy who is worried about receding. i have a full head of hair but it is a bit thin in the left hand side at the temple. i have been told it has always been like this. my mothers dad went bald before 30, my dads dad did not go bald. but my dad has receeded a bit on top. when my hair is dry u cannot see my scalp but when wet it parts alot and seems thin!!also i was told that my head may have got bigger which may make it seem like it has receded! am i worrying over nothing??

Growing boys with growing and maturing heads, do not thin out their hair. You should get your scalp mapped out for miniaturization to find out if you have early genetic hair loss.
