Abstract
Abstract A hairbrush includes a plurality of flexible concentric rings supporting bristles or teeth. The flexible concentric rings are flexibly connected by flexible hinges which allow the rings to deflect away from the direction of brushing. The teeth carried by the concentric rings are stiff, allowing deep penetration of the hair. The flexibly mounted concentric rings allow the stiff teeth to easily slip past any snags or knots encountered in the hair by deflecting away from the direction of brushing.
