This curling iron made unpredictable curls, and then they didn't hold. I have thick but fine almost shoulder-length hair. For years, I have been using the Hot Tools gold-plated 1.25" iron. Recently, my hair became EVEN more curl-resistant than it had been in the past. So I thought I'd try a smaller diameter barrel. I stayed with the same brand and style, but changed to this model with the tourmaline finish. So, I'm going to return it and order the Hot Tools 1" with the gold finish, and see if that does the trick.
