Abstract
Abstract This hair drier has a fan for producing a stream of air, a heater for heating the stream, and a cubicle adapted to be fixed to a wall. The cubicle has a forwardly and downwardly open aperture for access of a person''s head to a head-receiving space defined by a lining which extends downwardly at the rear of the cubicle to such an extent as to dry shoulder-length hair. The lining extends forwardly over a person''s head, and downwardly over the user''s forehead to dry hair at the user''s forehead. In use the cubicle is preferably fixed to a wall, for instance at a height which is adjustable to allow a user to stand comfortably.
