Detangling-straightening comb for hairdryer or blower brush

Abstract

A hair detangling-straightening comb is intended to be fastened to the blowing end of a hair drying and styling appliance. The comb has a hollow body with an air inlet and a support having a plurality of teeth. The teeth have a widened base on the proximal side and a pointed tip on the distal side. A sectional profile of the teeth on the proximal side has a wavy shape that is progressively truncated over the wavy portions starting from the proximal side towards the distal side of the teeth.
