It depends upon what portion of the electricity use is for the heating element, and what portion is used for the fan. The Heating element is a resistive load, and is 100% efficient. The fan is an inductive load, and is not 100% efficient. I imagine that in most hairdryers they are not putting super high-efficiency motors in to drive the fans, but I also suspect that the vast majority of the energy used will be by the heating coils, so your overall efficiency will likely still be very high.
