Abstract
A diffuser attachment for a hair dryer includes a perforated face plate having a diameter between 2 and 6 times that of the nozzle portion of the hair dryer to which the diffuser is attached, and a plurality of spaced apart slot portions in the sidewall of the diffuser attachment enabling unheated air to enter the diffuser attachment during use and enabling heated air to escape after use, thus avoiding overheating.
