We don’t know too many people that are using their hair straighteners vertically, but there must be a few since ISA has made a point of clarifying that this model is intended only to be used horizontally, i.e., perpendicular to your hair. According to the manufacturer, using the hair straightener horizontally reduces hair pulling for a more comfortable experience. This may be particularly important to you if your hair tends to knot easily or you have unruly curls and texture.
Easy-to-use and safer for strands, the ghd Classic 1" Inch Styler with ceramic heat technology operates at the optimum 365°F styling temperature for smooth, no-frizz styling.
