Abstract: A hair drier hood is formed of an approximately sickle shaped laterally open cap (1) and a pair of arms (4, 5) located on the opposite sides of the cap. Each of said arm has a heating element (12), and a plurality of spaced apart heating elements (8) are located in the cap. A box shaped projection (2) is located at the end of the cap arranged to be located adjacent the neck of a person. A blower (13) is positioned in the projection (2) and arranged to direct air into the cap. In the cap (1) the heating elements (8) are separated from ducts (15, 16) by a reflector (10). The reflector (10) contain air outlet orifices (9) spaced apart along the cap. Air is directed through the ducts (15, 16) along the length of the cap (1) and passes through the air outlet orifices (9) and toward the head of the person using the drier.
