Abstract: A fluid diffusion member, particularly useful for insertion in the hood of a hair dryer, or the like, wherein the diffusion member is shaped congruently and adapted to be retained within the hood of the hair dryer so as to diffuse the heated air emanating from the source of heated fluid so as not to disrupt the hairdo, or the like, of the individual using the hair dryer. The fluid diffusion member is, in one embodiment, dome-shaped and molded of an open pore polyurethane foam which satisfactorily breaks up the air, permitting adequate drying without attendant disruption of the hairdo. In other embodiments, interconnected segments make up the diffusion member.
