I have a Chi iron also, I've had mine for about 3 or so years now. I don't use it that much anymore because I cut my hair pretty short and I used to only have a little bit of a wave anyways. So the chi does work great, it's supposed to cause less damage because it's ceramic. I'm not so sure about it not causing any damage at all though. What you can do is get a product that protects your hair from the heat. I use Bumble and Bumble Styling Lotion. Not only does it work as a styling product, but it also puts that protective layer on your hair so that when you go to blow dry your hair, or straighten your hair it keeps it from getting damgaged. You can find it online or at most nice salons. There's similar products also, but I just can't think of any others. Hope this helps.
