Haircut style? any idea? anyone.?

Are there any cute or any good haircut style for wavy hair? I have long natural wavy hair and and my wavy hair is kind of loose because my hair is becoming a little bit straight. It is also a little thick and don't use any hair gel or spray and don't use any heat very much. I use heat 2 time a month. My length of my hair is middle of my back. Website will be wonderful.
