Help!! How do you grow really thick hair?

Hey,

Well i'm a guy and i have quite thick hair which is pretty annoying. I want
to grow my hair long but its pretty thick, is there any way of growing my
hair long (not to long, that skate/punk look)? At the moment it grows to
around the middle of my ears, but thats not all over thats just on the side
and the rest is like bobbing out around the top and really thick looking
and it dosn't all grow down. Is there anything you can get to get your hair
less thick?

Oh and i usally just wear a hat but then it goes all curley and the bottem,
and if i don't wear a hat it goes frizzy.

Please help!! Thanks!
