Like many dryers, the Wahl PowerDry has a cold shot button. It also features 3 heat settings and 2 speed settings operated from rocker switches on the handle and it comes with a couple of nozzles (1 slim, 1 wide) for some drying versatility. What makes it different from other dryers is the tourmaline grill that lies across the air output; the semi-precious gemstone tourmaline is a glittering mass of negative ions just waiting to be released by a blast of heat from the PowerDry’s 2000-watt motor. These negative ions travel with the heated air and lock moisture into the hair’s cuticles, giving it tremendous shine and delivering a sleek finish to your style. As you might expect from a professional dryer, the Wahl PowerDry comes with a salon-length 3-metre cord, designed to help you reach right round any client.
