Abstract
A method and apparatus for drying hair is disclosed. A helmet defines a space adjacent the hair and vacuum apparatus reduces the air pressure within the space. Infrared lamps apply infrared radiation to the hair and the moisture bearing fluid is removed from the space by a pump. In some embodiments, the fluid is dehumidified and recirculated. Preferably, temperature and pressure controls are provided and, in some embodiments, a co-solvent is added to a recirculated air stream.
Claims19
A method of drying hair comprising the steps of establishing an enclosed space surrounding the hair to be dried separate and sealed from atmosphere, reducing the air pressure within and throughout such space to a sub-atmospheric pressure below ambient pressure, maintaining the sub-atmospheric pressure throughout the space and applying infrared radiation to the hair.
Apparatus for drying hair comprising, in combination, a helmet having an open end, said helmet defining an enclosed space adjacent the hair to be dried sealing means adjacent said open end of said helmet for separating said enclosed space from the atmosphere, vacuum means including a vacuum head mounted within such space and vacuum pump means located exterior of such space in fluid communication with said vacuum head for reducing the air pressure throughout such space, wherein a sub-atmospheric pressure is maintained throughout such space during drying and infrared means within such space for directing radiant energy toward the hair.
