Male Thin Brown Curling/Flipping Hair... HELP!

by Zach

Here is what my hair looks like after I iron it.

I have thin brown hair. I know pretty much nothing about hair and hair products so the only thing that goes in my hair is shampoo. My hair really bothers me because it curls and flips on the sides back and front but not on the top of my head, which looks really bad because I have thin hair.

It doesn't matter if my hair is short or medium length it always does this. So I blow dry and straight iron my hair and it looks fine.

My problem is that by the end of the day it curls and flips again. Also if I sleep in I don't have time to do anything to my hair so I end up wearing a hat all day.

What can I do with my hair?
