This is what we used...it's by Conair and ceramic.
This has to be the easiest way to do dramatic wave curls I have ever tried. Literally just take a strand about 1 inch wide, close it "flat-iron style" over the hair at the scalp, then move down the strand (overlaping to keep it neat). Even did it on myself very easily (you do need a mirror to see where to place it next). The application reminds me of the way you krimped way back when.
I immediately told my friends with girls about this one!
