Curls Without Heat: Headband

It seems to be that people are figuring out ways to get there straight hair to curl without heat. I've notice lots of peopled will use a head band to curl there hair over night. Sometimes this can cause your hair to to become fuzz if you have thin hair or its to dry. The other problem can be that the front will curl but the back won't, probably because you hgave to much hair in thwe back and its to wet in the back.
