A superior heat protection spray that works from the inside out, helping to protect hair from thermal damage and breakage. With a weightless formula and no added build-up, the CHI 44 Iron Guard helps to seal the cuticle and works to prevent future damage. This spray helps to protect your hair from the heat of the iron, while adding shine at the same time. It's great for any hair type, but especially ideal for dry, curly, or thick hair because it will help reduce frizziness and flyaways.
