Abstract: A hairbrush head is connected to a front end of a handle and includes a solid cylindrical body having a bristle holder made of metal sheet attached to a circumferential surface thereof. The hairbrush head is so shaped that a space is provided between the circumferential surface of the cylindrical body and the bristle holder, so that hot air from a hairdryer passes through holes provided on the bristle holder into the space to circulate therein and thereby evenly distributes heat over the hairbrush head to facilitate easy hair setting.
