This iron is built with Pulse Technology® for Fast Heat-Up and Instant Heat Recovery, which means NO "hot spots" and continuous even heat for, excellent straightening and long lasting results, for perfect straight hair every time. The Nano Ceramic® surface of this iron is engineered exclusively to emit far-infrared heat that is kinder to the keratin protein in your hair. Keratin refers to a family of fibrous structural proteins and is the key structural component of hair. The heat produced by the "KIS" iron straightens your hair and eliminates frizz and curl by closing the cuticle of the hair making the hair smooth and shiny. Different hair types require different heats to close the cuticle and achieve straight, shiny hair without damage. Nano Technology is a method of processing the ceramic ingredients and applying them in nano-sized particles to the plates of the flat iron. This increases the effectiveness of ceramic's ability to straighten the hair cuticle and a greater benefit is gained from the far-infrared heat.
