ABSTRACT:
The hairbrush includes an elongated member having a handle segment and a bristle substrate segment. The bristle substrate defines an hourglass shaped core having a central region that is either cylindrically shaped or has a substantially similar elliptical cross-sections bounded on either side by dimensionally larger end regions. A plurality of hairbrush bristles are attached over the bristle substrate. The hairbrush bristles can have substantially equal lengths such that the outer peripheral portions of the plurality of hairbrush bristles defines an hourglass shape. Alternatively, the hairbrush bristles can have varying lengths such that the bristle ends form a planar surface or substantially cylindrical surface. Rectangular and oval shaped bristle substrates are also disclosed. The plurality of hairbrush bristles may be disposed over the bristle substrate individually or in groups of small bundles, and can form varying patterns such as a linear pattern, a spiral pattern or a predetermined, spaced apart pattern.
