A pulsating attachment for use with an electric hair dryer that has a tubular end through which air is expelled is described comprising a coupling section with an asymmetrical and unbalanced single impeller supported in the coupling for rotation therein and mounting structure connecting the coupling and the tubular end whereby the expelled air rotates the impeller and, due to its unbalanced mounting, creates a pulsating flow of air at a constant flow rate from the coupling. This results in a rotating path of pulsating air on the head of the user to create a fluffing action.
