Make sure you use a heat protecter for starters. Another thing that works is make sure it is a ceramic straightener, most straighteners are ceramic anyways but just make sure. A more expensive one is a chi but only the coating is ceramic underneath the ceramic coating is a metal because it helps the conduction of the heat. A really good one that is a little more expensive is a royale straightner but the plates are ceramic all the way through so it is better for your hair. I have used both but i prefer the royale because it glides over my hair much more smoothly and my hair doesn't frizz and easily afterward. Chi can be bought at lots of hair salons, I bought mine from Regis a hair salon in most malls, My Royal is sold in one of the booths at the mall but if you dont have a booth in your mall you can buy them on amazon
I don't think there are ones like that.i mean there are really good ones but they cost alot more..um you should buy a heat protectant and spray it in your hair before you use any heat.try not to straighten your hair alot because you want to keep it as healthy as possible.
paul mitchell straightners are probably the best straightners you can get your hands on. i love it!
