Far Infra red is produced from CHI 44 ceramic in all CHI products and tools giving the user amazing performance with every product. CHI Products and tools penetrate deeper into the hair and the results speak for themselves. FAR Infrared is the longest frequency of the infrared spectrum; it is invisible to human eyes. Far-infrared frequency can penetrate up to 1 ½ inches (4 cm) inside of the skin as well as inside of the hair. Far Infrared is drying the hair from inside out due to its ionic charge and colors are penetrating deeper. Far Infrared is heating up objects (hair/brush) not just the air. The recent studies have also shown that it can increase the blood circulation and metabolism. It can also help to maintain our general health.
