Curl enhancers have never done much for me. I just put some of my leave-in on the frizzy spots when I need to. Trying a curl enhancer isn't a bad idea though, it could work for you, you never know. Also, my hair looked better when I stopped using gel and started using cream. I've since switched to mousse, but cream is good too, might be another thing worth trying.
