NOZZLE

An attachment for a hair styling apparatus includes an air inlet for receiving airflow from a hair styling apparatus, an air outlet, a duct for conveying air from the air inlet to the air outlet, at least one aperture in a wall of the duct, and a guiding wall within the duct and in proximity to the at least one aperture, wherein the guiding wall forms a barrier at an upstream side of the at least one aperture. Cool ambient air is entrained through each aperture into the attachment by the heated airflow from the hair styling apparatus. The entrained airflow passes internally along the wall of the duct and functions to minimize the temperature of the wall.
