Go get a "Julia Roberts haircut". take a look at the hairstyles she's had, because she has really poofy hair. And go thru and see what styles you like the best and pick it for yourself.
When you have poofy or thick hair it is best to have layers so that you can get rid of some of the bulk. Another great choice is to have your hair thinned with the special scissors that hair stylists have. Grow your hair out longer than shoulder length because then it will lay better.
I recommend getting a style that thins your hair out. It's also important to take into consideration the shape of your face. Products also help to tame an uncontrollable mane as well as styling techniques. As questions the next time you have your hair done.
Well if you embrace your locks go for layers and angles. When your hair is nice and thick you can pull off this look. If you want to detur from it, get it thinned out with a razor and go for something short.
