Heated hair straightening brush and heated hair straightening dryer brush

Abstract

The present invention relates to a heated hair straightening brush (a “heated straightening brush”) as well as a heated hair straightening brush that also dries hair (a “heated straightening dryer brush”). As one non-limiting example, the invention relates to a heated straightening brush and/or a heated straightening dryer brush that has a slightly curved front to the brush head, which is heated, and where the exposed edges on the sides of the brush head, also heated, are curved to help style the hair. As an alternative non-limiting embodiment, the invention relates to a heated straightening brush and/or a heated straightening dryer brush having a curved front and curved sides of the brush head where the density of bristles and 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. As a further non-limiting embodiment, the invention relates to a heated straightening brush and/or a heated straightening dryer brush having a curved front and curved sides of the brush head where the brush head is textured and/or coated in whole or in part, including but not limited to having coating in the shape of strips and/or channels at any location on the brush head. The invention also includes, but is not limited to, a heated straightening brush and/or the heated straightening dryer brush having a curved front and curved sides and further having a handle that is detachable from the brush head. The invention further relates to the brush head for a heated hair straightening brush and/or a heated straightening dryer brush where the front and both sides of the brush head are curved and heated and at least a portion of the brush head has a texture or a coating.

What is claimed is: 
     
         1 . A heated straightening brush comprising a brush head having a front surface, two side surfaces, and a back surface, wherein the front surface of the brush head is curved and wherein the two side surfaces of the brush head are curved. 
     
     
         2 . The heated straightening brush of  claim 1 , wherein the front surface of the brush head is heated and wherein both of the side surfaces of the brush head are heated. 
     
     
         3 . The heated straightening brush of  claim 1 , wherein the front surface of the brush head has bristles or tufts. 
     
     
         4 . The heated straightening brush of  claim 3 , wherein neither of the side surfaces of the brush head have bristles or tufts. 
     
     
         5 . The heated straightening brush of  claim 3 , wherein at least one of the side surfaces of the brush head has bristles or tufts, and wherein the overall density of the bristles or tufts on said at least one side surface is less than the overall density of the bristles or tufts on the front surface of the brush head. 
     
     
         6 . The heated straightening brush of  claim 1 , wherein at least a portion of one surface of the brush head has a texture and/or a coating. 
     
     
         7 . The heated straightening brush of  claim 6 , wherein the texture and/or coating is in the shape of strips and/or channels. 
     
     
         8 . The heated straightening brush of  claim 1 , wherein the side surfaces of the brush head have a radius of curvature R s  and the front surface of the brush head has a radius of curvature R l , wherein R s  is less than R l , and wherein the ratio of R s  to R l  is about 1:1.1 to about 1:10. 
     
     
         9 . The heated straightening brush of  claim 1 , further comprising a dryer mechanism, wherein at least one surface of the brush head is heated, directly or indirectly, by a heating mechanism other than exposure of the surface to hot air of the dryer mechanism. 
     
     
         10 . A heated straightening dryer brush comprising a brush head having a front surface, two side surfaces, and a back surface, wherein the front surface of the brush head is curved and wherein the two side surfaces of the brush head are curved. 
     
     
         11 . The heated straightening dryer brush of  claim 10 , wherein the front surface of the brush head heated and wherein at least one of the side surfaces of the brush head is heated. 
     
     
         12 . The heated straightening dryer brush of  claim 11 , wherein the both of the side surfaces of the brush head are heated. 
     
     
         13 . The heated straightening dryer brush of  claim 10 , wherein the front surface of the brush head has bristles or tufts. 
     
     
         14 . The heated straightening dryer brush of  claim 13 , wherein neither of the side surfaces of the brush head have bristles or tufts. 
     
     
         15 . The heated straightening dryer brush of  claim 13 , wherein at least one of the side surfaces of the brush head has bristles or tufts, and wherein the overall density of the bristles or tufts on said at least one side surface is less than the overall density of the bristles or tufts on the front surface of the brush head. 
     
     
         16 . The heated straightening dryer brush of  claim 10 , wherein at least a portion of one surface of the brush head has a texture and/or a coating. 
     
     
         17 . The heated straightening dryer brush of  claim 16 , wherein the texture and/or coating is in the shape of strips and/or channels. 
     
     
         18 . The heated straightening dryer brush of  claim 10 , wherein the side surfaces of the brush head have a radius of curvature R s  and the front surface of the brush head has a radius of curvature R l , wherein R s  is less than R l , and wherein the ratio of R s  to R l  is about 1:1.1 to about 1:10. 
     
     
         19 . The heated straightening dryer brush of  claim 10 , wherein at least one surface of the brush head is heated, directly or indirectly, by a heating mechanism other than exposure of the surface to hot air of the dryer.
