hair help

I have super thick wavy hair. I love my hair but my issue is I have to straighten it everyday. Even if I want to let it just be wavy, it is so unruly I have to still do it. Even my bangs curl like crazy. Because of this my hair is becoming super dry and dead. Even with heat protectant spray. I really want to stop ironing my hair so it can become healthy but how can I deal with this crazy hair? Any hair tips or tricks?  Plus here is a picture of my hair  without straightening. Thanks!
