My hair is naturally a combination of 3A and 3B. I would like to get it to be more 3A and/or wavy. I don't know anything at all about straightening the hair using chemicals, and I am looking into it because I am just tired of having to use the curling iron to get bigger, less 3B curls.

This is my hair after I use the curling iron to lessen the curls (hopefully it works):
