The Royale Smart hair straightener features ceramic plates, far-infra red heat, preserving moisture in the hair shaft and protecting the hair cuticles from damage. In fact regular use of the styler results in healthier hair. Since buying this flat iron, I have purchased other styling tools that also serve to straighten my hair. This flat iron still works great (as is much healthier for your hair than a typical flat iron) but no longer use it.
