I use it combined with BRHG. It gives me great curl definition, frizz control, and decent hold, but since I need a hard hold I add the BRHG. Our dews are generally fairly moderate, but can reach into the 60s (actually are in the mid-60s next couple of days) and KCCC will still work decently for me. I haven't tried it in dews over 70 though. Many people really love it, but some who try it hate it, so YMMV!
