In a second preferred embodiment (not shown), the sides of the brush head contain bristles or tufts of any kind or in any pattern so long as the density of the bristles or tufts on the sides of the brush head is less than the density of the bristles or tufts on the front of the brush head. The bristles or tufts associated with the present invention are not limited in material, size, or shape; any bristle or tuft in any configuration may be used so long as there are no bristles or tufts on the sides of the brush head or, alternatively, the density of the bristles or tufts on the sides is less than the density of the bristles or tufts on the front of the brush head.

[0051] As non-limiting preferred examples, less density of bristles or tufts can be obtained by having fewer bristles or tufts on the sides than on the front of the brush head, by having finer bristles or tufts on the sides than on the front of the brush head, or by having bristles or tufts of a different shape, thickness, height, or kind on the sides of the brush head versus the front of the brush head. In another embodiment, the sides of the brush head may contain bristles or tufts so long as the bristles or tufts on the sides create less friction per inch against hair than the bristles or tufts on the front of the brush head. As one non-limiting preferred example, the sides may have a single row of bristles or tufts

[0052] In preferred embodiments, the bristles or tufts of the heated straightening brushes and/or the heated straightening dryer brushes, whether at the front of the brush head or on the side of the brush head or at both places, are placed on or through a solid surface. In some preferred embodiments, the bristles or tufts could be placed in rows, patterns, designs, or at random. In some preferred embodiments, the arrangement of bristles and tufts may, but are not required to, vary between the front of the brush head and the sides. As non-limiting examples of preferred embodiments, the bristles or tufts (a) could be flexible, semi-flexible, firm, rigid, or any combination thereof; (b) could vary in height or be uniform in height; (c) could have a variety of diameters or cross-sections, be fin-shaped, taper, be uniform in diameter, or any combination thereof; or (d) could be set in waves and/or have a ball edge. Multiple types of bristles or tufts may be combined on the same heated straightening brush and/or the heated straightening dryer brush. In one embodiment, the bristles or tufts may be suitable for use only on dry hair. In another embodiment, the bristles or tufts may be suitable for use only on damp hair. In another embodiment, the bristles or tufts may be suitable for use only on wet hair. In other embodiments, the bristles or tufts may be suitable for use on either wet or dry hair. The bristles or tufts may be made of any natural, synthetic, or a combination of natural and synthetic material that will withstand the heat generated by the heated hair straightening brush, including but not limited to silicone bristles or tufts, silicone-coated bristles or tufts, nylon bristles or tufts, plastic bristles or tufts, metal bristles or tufts, or coated metal bristles or tufts.

[0053] In some preferred embodiments of the heated straightening brush and/or the heated straightening dryer brush, the brush head has texture and/or a coating. As preferred examples, the sides, front, and/or back of the brush head may have texture and/or a coating located on all or substantially all of at least one side of the brush head. In another preferred example, all or substantially all of brush head of the heated straightening brush and/or the heated straightening dryer brush may be coated and/or textured. In one preferred embodiment, only the front and sides of the brush head may have texture and/or a coating in whole or in part. In some preferred embodiments, the areas of texture and/or coating may be in the shape of strips, dots, channels, or other shapes or patterns or at random on any surface of the brush head.

[0054] In some preferred embodiments, one or both of the sides of the brush head may be fully or partially covered with texture and/or coating. In one preferred embodiment, the sides of the brush head may have texture and/or coatings in the shape of strips or channels. In other preferred embodiments, one or both of the sides of the brush head may not be coated, may not be textured, or may not be coated or textured.

[0055] In preferred embodiments, the coating material may protect the hair from heat and/or promote shine. Such coatings, when present, can include, but are not limited to coatings made of silicone. Other preferred examples of coatings may include, but are not limited to silicone strips, silicone strips with silicone bristles, and/or silicone channels.

[0056] In certain preferred embodiments, heated straightening brush and/or the heated straightening dryer brush having a brush head where one or both of the sides do not have any bristles or tufts may have a coating in any pattern or placement.
