A hair brush ( 10 ) has two portions ( 12, 24 ) joined by a hinge ( 16 ) at one end and each having brush heads ( 18, 20 ) at the other end. In profile, the brush heads are curved such that one is concave and the other is convex and, as a result, they nest within each other when closed together and apply their contour to hair trapped between the brush heads.
