Abstract
Abstract A hair dryer of the type having a rigid hood within which a person''s head is positioned in order to dry the hair by means of heated air discharged through perforations on the inner wall of the hood toward the hair to be dried. Means are provided to circulate steam into the helmet and out through the perforations whereby the steam fills the volume under the hood. A detachable extension is provided on the hood to extend the lower edge of the hood downwardly to horizontal plane thereby providing an enclosure within which the entire head may be received for the purpose of treating the hair and face with steam. Control means on the enclosure permit adjustment of the level of steam enclosed within the hood and the extension.
