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.
Claims15
A hairbrush for use in untangling hair, comprising:
- a body portion free of a handle extension;
- a plurality of flexible bristles uniformly distributed on the body portion and projecting from 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 shorter length bristles and longer length bristles, at least some of the shorter length bristles and longer length bristles arranged in alternating linear rows of longer length bristles and shorter length bristles, with at least some of the shorter length bristles and longer length bristles arranged in alternating linear rows being offset relative to those in adjacent rows;
- the shorter length bristles sized and dimensioned to bend at a first distance from the body portion, with a first ratio defined as a ratio of the first distance to the length of the shorter length bristle;
- the longer length bristles sized and dimensioned to bend sideways at a second distance from the body portion, with a second ratio defined as a ratio of the second distance to the length of the longer length bristle;
- the second distance greater than the first distance and the second ratio greater than the first ratio;
- and
- wherein the length of the shorter length bristles is approximately equal to the second distance.

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;
- the first bristles having a length approximately equal to a height of the second bristles when the end of the second bristles is 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 each of the first bristles has a first taper structure and each of the second bristles have a second taper structure, with the first taper structure differing from the second taper structure.
