Hair straightening brush

1. A hairbrush, comprising:

a plurality of heating elements protruding from a face of the hairbrush, the plurality of heating elements defining a hair treating area dispersed on at least a part of the hairbrush's face at a specified density;

a plurality of heat insulating spacers each of which includes an end spaced from the face of the hairbrush, the plurality of heat insulating spacers configured on top of at least some of the plurality of heating elements, thereby giving rise to a space between the plurality of heating elements and a user's scalp during use; and

a plurality of heat insulating elongate peripheral spacers disposed at least around a portion of the hair treating area of the hairbrush, each of the plurality of heat insulating elongate peripheral spacers including an end spaced from the face of the hairbrush, at least some of the ends of the plurality of heat insulating elongate peripheral spacers located closer to the face than the ends of the plurality of heating insulating spacers.

2. The hairbrush of claim 1 , wherein the plurality of heating elements are arranged to maintain a specified distance between protruding ends of the plurality of heating elements and the user's scalp at between 1 mm and 30 mm.

3. The hairbrush of claim 1 , wherein the specified density of the plurality of heating elements is between 0.2 per cm 2 and 15 per cm 2 .

4. The hairbrush of claim 1 , wherein at least some of the plurality of heat insulating spacers that are connected on top of corresponding ones of the plurality of heating elements comprise silicon caps.

5. The hairbrush of claim 1 , further comprising a heat source arranged to heat the plurality of heating elements.

6. The hairbrush of claim 1 , wherein at least some of the plurality of heating elements comprise internal heat sources.

7. The hairbrush of claim 1 , further comprising a control unit arranged to control the plurality of heating elements.

8. The hairbrush of claim 1 , configured as a one-sided brush.

9. The hairbrush of claim 1 , wherein the specified density of the plurality of heating elements and a specified density of the plurality of heat insulating spacers are variable across the face of the hairbrush and the specified densities are related to maintain the specified distance between protruding ends of the plurality of heating elements and the user's scalp under at least one usage scenario.

10. The hairbrush of claim 1 , wherein the plurality of heat insulating elongate peripheral spacers are stiff and extend around at least a portion of the hair treating area.

11. The hairbrush of claim 1 , wherein the plurality of heat insulating elongate peripheral spacers are integrated with the face of the hairbrush around the heating area.

12. The hairbrush of claim 1 , wherein the plurality of heating elements are arranged in a pattern resulting in a plurality of substantially parallel undulating paths in at least one direction of hair strand entry.

13. The hairbrush of claim 1 , wherein the plurality of heating elements are arranged in a pattern resulting in a plurality of substantially parallel undulating paths in at least one direction of hair strand entry, and wherein the plurality of heating elements are disposed in a pattern offering a smooth path extending at an orientation other than the plurality of substantially parallel undulating paths in at least one direction of hair strand entry.

14. The hairbrush of claim 1 , wherein the plurality of heating elements are arranged in a pattern such that, along one axis, the plurality of heating elements are equally spaced.

15. The hairbrush of claim 1 , further comprising:

a heating plate extending over the face of the hairbrush;

wherein the plurality of heating elements are integrated with and thermally coupled to the heating plate;

wherein the heating plate and the plurality of heating elements collectively define the hair treating area.

16. The hairbrush of claim 15 , wherein the heating plate is curved.

17. The hairbrush of claim 15 , wherein the heating plate is convexly curved.

18. A method, comprising:

arranging a plurality of spacers to maintain a specified distance between protruding ends of a plurality of heating elements protruding from a face of a hairbrush and a scalp of a head that is being brushed, the hairbrush further including a plurality of heat insulating elongate peripheral spacers disposed at least around a portion of the plurality of spacers and the plurality of heating elements with ends of the plurality of heat insulating elongate peripheral spacers being closer to the face of the hairbrush than ends of the plurality of spacers;

wherein the plurality spacers are dispersed on at least a part of the hairbrush's face at a specified density selected to assure maintaining the specified distance with respect to a resilience of the plurality of spacers.

19. The method of claim 18 , further comprising connecting at least some of the plurality of spacers on top of corresponding ones of the plurality of heating elements.

20. The hairbrush of claim 1 , wherein the plurality of heat insulating elongate peripheral spacers are disposed around substantially an entirety of the hair treating area of the hairbrush including the plurality of heating elements and the plurality of heating insulating spacers.
