  • Patent number: 4030158
    Abstract: A hair brush, particularly useful for blow waving has a back of open frame construction to facilitate the flow of hot air. Folded single bristles are inserted into holes on the front surface of the brush in a staggered relatively uniform arrangement. The bristles are relatively thick in diameter and include a bead at one end to avoid scratching the scalp. The thickness of the bristles enables them to withstand the heat of the air used in blow waving.
