ghd Helios™ has a powerful new generation brushless motor whereas the ghd Air® features a brushed AC motor. The ghd Helios™ is also lighter than ghd Air® and features an enhanced ergonomic design. This allows the weights to be more evenly distributed across the hairdryer for a lighter styling experience. We also offer the ghd flight® which is our travel dryer to allow you good hair days wherever you are. For more information please visit our comparison page.
