So what makes the ghd air ™ different? Well, almost everything. Its much more powerful than a normal hairdryer. The ghd air ™ doesn't just dry your hair, it uses advanced ionic technology to lock in moisture for softer, shinier results that last for longer, with far less frizzing. Variable power and temperature controls, plus the choice of two nozzles, allow you to tailor your blow-dry to your hair type, while a cool shot button helps you set your style in place with a blast of cold air.
