The right side of my head is different than the left side. Any suggestions?

I am asking if there's any way to make the both sides of my head to look the same.At first I thought it was my hair but when I got a haircut there's a some sort of a flat on the right side of my skull.When I look at the mirror the left side looks normal with its round sides but when I look at my right side, needless to say my self esteem deteriorates.Is there any way to change that?
