Abstract
A hair care device for use in untangling hair includes a body portion and a plurality of substantially parallel flexible bristles made of soft plastics material and projecting from the body portion. The bristles are arranged such that over at least a part of the area of bristles, some of the bristles are of shorter length. The bristles and the shorter length bristles are interspersed over the at least part of the area of bristles.
Claims16
A hairbrush for untangling hair, the hairbrush comprising:
- a body portion having a plurality of flexible bristles projecting therefrom such that each of the plurality of flexible bristles is substantially parallel to the rest of the plurality of flexible bristles;
- the plurality of bristles including a plurality of first bristles and a plurality of second bristles alternately arranged to position first bristles adjacent second bristles, the first bristles extending from the body portion to a first distance and the second bristles extending from the body portion to a second distance with the first distance less than the second distance;
- wherein the first distance is approximately equal to a height of the second bristles when the ends of the second bristles are bent sideways,
- wherein each of the plurality of second bristles is configured and dimensioned and the plurality of second bristles is arranged to thereby bend to engage tangled hairs to position a free end of the second bristles proximate free ends of the first bristles and to thereby release hair that remains tangled to the first bristles so that the first bristles may untangle hair that remains tangled;
- and
- wherein the plurality of flexible bristles directly projects from a contiguous concave surface of the body portion.

A hairbrush for untangling hair, the hairbrush comprising:
- a body portion having a plurality of flexible bristles directly projecting from a contiguous concave surface of the body portion such that each of the plurality of flexible bristles is substantially parallel to the rest of the plurality of flexible bristles;
- the plurality of bristles including a plurality of first bristles and a plurality of second bristles arranged in alternating linear rows of first bristles and second bristles, the first bristles extending from the body portion to a first distance and the second bristles extending from the body portion to a second distance with the first distance less than the second distance;
- wherein the first distance is approximately equal to a height of the second bristles when the ends of the second bristles are bent sideways,
- wherein the rows of first bristles and second bristles are offset relative to those in adjacent rows to centrally dispose each first bristle between second bristles except at a periphery of the body portion;
- and
- wherein each of the plurality of second bristles is configured and dimensioned and the plurality of second bristles is arranged to thereby bend to engage tangled hairs to position a free end of the second bristles proximate free ends of the first bristles and to thereby release hair that remains tangled to the first bristles so that the first bristles may untangle hair that remains tangled.
