get a ceramic one it doesn't pull on ur hair
i JUST saw a study about this...I can't remember which was rated the best....you should google it or something. whatever you do, don't spend all your money on a CHI straightener. i bought one. they are very expensive but totally overrated. Its not that good on my thick wavy hair. i think the best one in the study was actually like a conair one that you can get at the drugstore for a good price. not sure....you should look it up
