Bodywaves

My hair is pretty long and layered. I really like it, but I want to try something different so that I don't get bored with it. I think that I look cute with curly hair, but I get tired of curling it all the time and it usually doesn't look the same by the end of the day. I think that I want to try a bodywave, to maybe give my hair some curl and a little volume. The only problem is that I don't know exactly what a bodywave is, what it will do to my hair, or if it might damage it. If you or anyone you know can help, please e-mail me a.s.a.p.!!!!Thanks for your help,Julie
