The Keratin Protect Intelligent Straightener reads your hair’s unique moisture levels 8x per second, for a personalised styling session every time. The white heat protection icon on the housing of the straightener will flash when moisture is being actively detected within your hair, so you can see the straightener protecting your hair as you style. The straightener will never apply a damaging dose of heat, leaving your hair 5x stronger* and reducing the risk of splitting and damage. Patented intelligent heat protection sensor measures moisture levels in the hair 8 x per second, for 3 x more protection from damage and breakage
