Tourmaline emits negative ions and infrared heat when pressure is applied to it. These phenomena are known as “pyroelectric” and “piezoelectric”.

For heating, the dryer uses infrared heat and a ceramic heater coil, along with an 1800 watt motor.

The infrared heat is better for drying hair, because it dries the hair shafts from inside rather than heating the surface.

The manufacturer claims that the negative ions also break up water molecules into smaller sizes on the hair surface, making them evaporate more quickly.

There is also a setting to release an ultra high dose of negative ions for damaged hair.

It’s available at here for $200. A travel-sized one is also available here and here.
