Hairstyles for wavy, hard-to-manage hair?

My hair is exactly the same way and I used to have the same problem. I find the longer my hair gets, the more the problems goes away. When you get your hair cut, ask for long layers and for them to thin your hair out. I used herbal essences shampoos and conditioners. Since you shouldn't wash your hair everyday because it needs the natural oils to keep it healthy, I use head and shoulders for frizzy hair on my in between days, but only a little bit. Also frizz ease by john freida works really good. Put a dime size glop in after you shower, when your hair is still wet. Hope I helped!
