A front nozzle for hair dryer, includes at least: one outer surface; one tapered portion extending along an axis; one flattened portion extending perpendicularly to the axis in fluid communication with the tapered portion and having a front slit at one end thereof; one main channel for the passage therethrough of air flow coming from the hair dryer, the main channel including at least one converging portion and at least one diverging portion downstream thereof; one secondary channel including at least one opening at the outside of the nozzle and at least one front opening downstream of the converging portion of the main channel to contact the air flow passing through the secondary channel with the main air flow passing through the main channel, the secondary channel extending between the outer surface and the main channel so as to thermally insulate, at least partially, the outer surface. |
