The ghd Helios™ boasts a new generation brushless motor, while the ghd Air® is equipped with a brushed AC motor. You'll find that the ghd Helios™ is lighter than the ghd Air® and has an improved ergonomic design. This design helps to distribute the weight more evenly across the hair dryer, for a lighter styling experience. We also have the ghd flight+, our travel dryer, so you can enjoy great hair days no matter where you are. For more details, please visit our comparison page.
