Japanese are crazy about the Nanocare dryer currently sold in Japan for 20,000 Yen ($167). Since it's release in July 2006, this dryer has already sold over 110,000 units thanks to its ability to reduce frizz and make hair strong and lustrous, reports Trends in Japan. The Nanocare EH5441 is is "equipped with a device that uses electricity to break down airborne moisture into micro droplets, which are delivered together with a stream of hot air. The minute droplets have a radius of 18 nanometers (a nanometer is a billionth of a meter) and contain minus ions. When they are sprayed on the head, oil that has built up on the scalp is loosened, making it easier to wash away. A subsequent shampoo leaves users feeling refreshed and reportedly makes hair lustrous and supple."
