Hair coloring sheets

Abstract

A hair coloring device comprises: a first rectangular sheet having a top edge, a bottom edge, opposing side edges, a front surface, and a back surface; a second rectangular sheet having top edge, a bottom edge, opposing side edges, a front surface, and a back surface; wherein the back surface of the second rectangular sheet is secured to the front surface of the first rectangular sheet after hair coloring is applied to hair disposed between the first rectangular sheet and the second rectangular sheet and wherein the top edges, bottom edges, and opposing side edges are aligned; and wherein the first rectangular member and the second rectangular member each comprise a transparent thermoplastic material. A process of coloring hair includes using the hair coloring device.

1 . A hair coloring device, comprising:
 a first rectangular sheet having a top edge, a bottom edge, opposing side edges, a front surface, and a back surface;   a second rectangular sheet having top edge, a bottom edge, opposing side edges, a front surface, and a back surface;   wherein the back surface of the second rectangular sheet is secured to the front surface of the first rectangular sheet after hair coloring is applied to hair disposed between the first rectangular sheet and the second rectangular sheet and wherein the top edges, bottom edges, and opposing side edges are aligned; and   wherein the first rectangular member and the second rectangular member each comprise a transparent thermoplastic material.   
     
     
         2 . The hair coloring device of  claim 1 , wherein the transparent thermoplastic material comprises polyvinyl chloride, polyethylene terephthalate, polycarbonate, polypropylene, polystyrene, polymethyl methacrylate, polyamide, acrylonitrile butadiene styrene, styrene acrylonitrile resin, or a combination thereof. 
     
     
         3 . The hair coloring device of  claim 1 , wherein the transparent thermoplastic material comprises polyvinyl chloride. 
     
     
         4 . The hair coloring device of  claim 1 , wherein the transparent thermoplastic material comprises polyethylene terephthalate. 
     
     
         5 . A method of coloring hair, comprising:
 applying a first transparent rectangular sheet to a portion of hair, wherein the first rectangular sheet has a top edge, a bottom edge, opposing side edges, a front surface, and a back surface;   applying hair coloring to the portion of hair;   applying a back surface of a second transparent rectangular sheet to the front surface of the first transparent rectangular sheet; and   monitoring the hair coloring process through the transparent first rectangular sheet and the transparent second rectangular sheet.   
     
     
         6 . The process of  claim 5 , wherein the first transparent rectangular sheet and the second transparent rectangular sheet each comprise a transparent thermoplastic material. 
     
     
         7 . The process of  claim 5 , wherein the transparent thermoplastic material comprises polyvinyl chloride, polyethylene terephthalate, polycarbonate, polypropylene, polystyrene, polymethyl methacrylate, polyamide, acrylonitrile butadiene styrene, styrene acrylonitrile resin, or a combination thereof. 
     
     
         8 . The process of  claim 5 , wherein the transparent thermoplastic material comprises polyvinyl chloride. 
     
     
         9 . The process of  claim 5 , wherein the transparent thermoplastic material comprises polyethylene terephthalate.
