You know what? Under normal, everyday circumstances, even straighties don't have frizz-free hair, or at least not perfectly smooth hair. I was getting really hung up on frizz, and then I started looking at all the heads of hair around me, and realized there was frizz on every single one of them. Even the most beautiful heads of hair had some level of frizz. So now I don't worry too much about being frizz and just try to keep the curls nice--if your curls look good, no one is really going to look at the frizz anyway.
