Few people know that blow-drying too hot can cause severe damage to the hair. Thanks to the Heat Brush, this is a thing of the past. The brush reacts to heat and helps you to prevent damage.HH Simonsen's innovative hairbrush technology sets new standards and allows you to control the heat during styling. When the hair dryer heats the head of the heat brush to 60°C, the black tube turns pink. This allows the stylist to regulate the heat to prevent damage to the hair. When the brush head has cooled down to a safe temperature, it turns black again. Since the ceramic tubes store the heat, styling is even faster when blow-drying. The heat-resistant "zig-zag" bristles adhere well and the ergonomic handle is particularly non-slip.The Heat Brush is available in three different sizes to shape the perfect curls and add volume to the hair. The unique Heat Brush also makes the hair silky soft, shiny and voluminous.
