Abstract
A hair dryer is provided which dries hair by directing thereagainst radiant infrared heat energy. The dryer includes an infrared (IR) energy source, such as a silicone carbide igniter, an anodized parabolic reflector for modifying the wavelength of IR radiation reflected by selective IR reflection, and a transparent IR filter lens on the outlet of the dryer to absorb unwanted wavelengths and a fan for developing a low velocity air stream which both cools the IR heat source and breaks up vapor layers on the hair. The wavelength of the IR radiation which is emitted is preferably from above about 0.8 microns to about 10 microns, which includes the maximum IR absorption spectrum of wet hair, i.e., about 2 to 3 and about 6 to 8 microns.
