Hair Extension and Method for Hair Extension

Abstract

A hair extension strip includes a hollow hair extension strip end piece and a number of extension hair strands that are embedded in the hair extension strip end piece. The hair extension strip end piece comprises a hair extension hollow tube having predetermined inner diameter and predetermined length. The hair extension strip is made by a process comprising steps of aligning ends of a predetermined number of hair strands; applying melted thermoplastic resin around the aligned ends of the hair strands, removing excess thermoplastic resin, forming a hollow hair extension strip end piece by wrapping the hair strands around a centering rod, and cooling the hair extension strip end piece with the hair strands embedded.

1 . A hair extension strip comprising:
 a) a hollow hair extension strip end piece; and   b) a predetermined number of extension hair strands that are embedded in the hair extension strip end piece.   
     
     
         2 . The hair extension of  claim 1 , wherein the hair extension strip end piece is made of thermoplastic resin of predetermined amount. 
     
     
         3 . The hair extension of  claim 2 , wherein the hair extension strip end piece comprises a hair extension hollow tube having predetermined inner diameter and predetermined length. 
     
     
         4 . The hair extension of  claim 3 , wherein the predetermined inner diameter is from about 1/16 inch to about ⅜ inch. 
     
     
         5 . The hair extension of  claim 4 , wherein the predetermined length is from about 1/16 to about ½ inch. 
     
     
         6 . The hair extension of  claim 5 , wherein the predetermined number of extension hair strands is from about 200 to about 450. 
     
     
         7 . The hair extension of  claim 6 , wherein the predetermined amount of thermoplastic resin is from about 0.01 gram to about 0.04 gram. 
     
     
         8 . The hair extension of  claim 3 , wherein the predetermined number of extension hair strands is from about 200 to 450. 
     
     
         9 . The hair extension of  claim 8 , wherein the predetermined amount of thermoplastic resin is from about 0.01 gram to about 0.04 gram. 
     
     
         10 . A hair extension strip that is made by a process comprising steps of:
 a) aligning ends of a predetermined number of hair strands;   b) applying melted the thermoplastic resin around the aligned ends of the hair strands,   c) forming a hollow hair extension strip end piece by wrapping the hair strands around a centering rod; and   d) cooling the hair extension strip end piece with the hair strands embedded.   
     
     
         11 . The hair extension of  claim 10 , wherein the predetermined number of extension hair strands is from about 200 to 450. 
     
     
         12 . The hair extension of  claim 11 , wherein the centering rod is circular and has a predetermined diameter. 
     
     
         13 . The hair extension of  claim 12 , wherein the predetermined diameter is from about 1/16 inch to about ⅜ inch. 
     
     
         14 . The hair extension of  claim 13 , further comprising step of removing excess thermoplastic resin so that the amount of thermoplastic resin applied on the ends of the hair strands is from about 0.01 gram to about 0.04 gram. 
     
     
         15 . The hair extension of  claim 14 , further comprising step of cutting the end of the hair extension strip end piece whereby the cut end has a flat cross section.
