Abstract
A hair brush includes a brush head and a bristle/handle assembly. The head includes a cylindrical barrel with a plurality of apertures in it, and the bristle/handle assembly includes a handle and a bristle tree assembly. The bristle tree assembly includes a central bristle rod, a plurality of bristles radially extending from the rod, and a connecting rod extending between the bristle rod and the handle. The bristle rod is positioned within the barrel, and the bristles extend through the barrel apertures in an extended position. The brush head and the bristle/handle assembly are not attached to each other, and instead they slide longitudinally relative to each other. When the handle and the barrel are slid apart from each other, the bristle rod travels with the handle to retract the bristles to a retracted positioned further within the barrel.
