Tourmaline is the best of the best when it comes to flat iron plates. It’s a semi-precious stone that is crushed and molded to create the gentlest straightening process for your hair. This quality material allows for the least damage and the greatest reward when it comes to using a flat iron. Some of the most popular ones from this category are the Corioliss Hair Straighteners and the Karmin Hair Straighteners.
