Why is one side more flat??

I part my hair to my left and that side is always nice and big but my right side is so flat.  How can I fix that?

Try alternating your parts.  I've been told by a stylist that because I sleep on one side can cause hair to behave different.  So I try to go to sleep on alternate sides.
Also, it's pretty common to have different curl patterns/types on different parts of your head, so that may be part of the issue.
