Hair dryer diffuser

A diffuser attachment for a hair dryer comprising a forwardly flared body portion wherein the maximum diameter portion thereof is at its forwardmost edge and having a reduced diameter rear neck portion adapted to be telescopically assembled on the air outlet end of the hair dryer, a diffuser plate concentrically mounted within said forwardly flared body portion with its forward edge spaced rearwardly of said forwardmost edge of said flared body portion and having a convex surface facing the flow of heated air from the hair dryer, the diameter of said diffuser plate being greater than the diameter of said air outlet end of the hair dryer but substantially less than the inner diameter of said flared body portion in a transverse plane defined by the forward edge of said plate whereby an annular gap defined therebetween has a radial dimension in said plane approximately one-fifth of the inner diameter of said flared body portion in said plane, and said forwardly flared body portion having a parabolic configuration with a short cylindrical portion at its forward edge.
