Dyson Supersonic Hair Dryer vs ghd Helios Professional Hairdryer

The ghd Helios is the stronger pick for most shoppers: more power, a ceramic heating element, and a higher owner rating across a much larger pool of reviews. The Dyson Supersonic wins on control and attachments, with four heat settings, three speeds and five magnetic tools that reviewers say hold steady and cut frizz. Both are well built; reviewers praise the Dyson's quiet airflow and the ghd's fast heat-up, though some find the Dyson heavy and a few report counterfeit units sold outside authorized channels.

• Choose the Dyson Supersonic if you want fine control over heat and speed and a full set of magnetic attachments for smoothing, diffusing and styling.
• Choose the ghd Helios if you have thick hair, want maximum airflow and fast heat-up, and prefer a simpler two-speed dryer with a long cord.
