Claims4
A hairbrush for styling hair, comprising:
- a rigid spine having a longitudinal axis, a top surface, and a bottom surface, and comprising first and second opposing portions, the first portion forming a head with a plurality of bristles attached thereto, and the second portion forming a handle;
- the first portion of the spine having a first curvature along the longitudinal axis of the spine, the first curvature causing the top surface of the first portion of the spine to be convex in shape along the longitudinal axis and causing the bottom surface of the first portion of the spine to be concave in shape along the longitudinal axis;
- and
- the second portion of the spine having a second curvature along the longitudinal axis of the spine wherein the first and second curvatures collectively form an S-shaped curve;
- and
- wherein the second potion of the spine further comprises a third curvature beginning near the junction of the first and second portions of the spine and extending through the distal end of the second portion of the spine, the third curvature being such that the resultant angle between the longitudinal axis and an imaginary line extending from the midpoint of a line across the narrowest portion of the proximal end of the second portion of the spine through the distal end of the second portion of the spine is about 1 degree and about 10 degrees.
