Hair extension

Abstract

A hair extension has a linear fixing member from which hairs perpendicularly branch, arranged in a flat configuration and is formed by two flexible tapes adhered to each other to form a fixing strip, with hairs embedded between the two flexible tapes by a fixing adhesive layer arranged therebetween. The tapes are flexible and made of thermoplastic material provided with a plurality of through holes over the surface thereof. The linear fixing member has at least one uncovered adhesive face provided with a pressure-activated and non-permanent further adhesive layer. The tapes are pressed against each other, so that the hairs and the adhesive material of the fixing adhesive layer are at least partially penetrated into the through holes, and the exposed adhesive face forms a support surface for a plurality of peelable films, each separated from the other by a further non-permanent adhesive layer.

1 . Hair extension ( 1 ), of the kind used for the thickening of hair, has comprising a linear fixing member ( 2 ) from which hairs ( 3 ) perpendicularly branch, arranged in a flat configuration, wherein:
 the linear fixing member ( 2 ) is formed by two flexible tapes ( 4 ,  5 ) adhered to each other so as to obtain a fixing strip, with hairs embedded between the two flexible tapes ( 4 ,  5 ) due to a fixing adhesive layer ( 6 ) arranged therebetween;   the tapes ( 4 ,  5 ) are provided with a plurality of through holes arranged about a surface thereof;   the linear fixing member ( 2 ) comprises at least one uncovered adhesive face provided with a pressure-activated and non-permanent further adhesive layer ( 8 ); and   the tapes ( 4 ,  5 ) being pressed against each other, so that the hairs ( 3 ) and the adhesive material of the fixing adhesive layer ( 6 ) are at least partially penetrated into said through holes the uncovered adhesive face providing a support surface for a plurality of peelable films ( 9 ), each being separated from one another by a further non-permanent adhesive layer ( 8 ), the surfaces thereof being configured to be uncovered comprise, with respect to said layer ( 8 ), an adhesiveness greater than the rear surface of each film ( 9 ), so that said surfaces configured to be uncovered be are adhesive surfaces.   
     
     
         2 . Hair extension ( 1 ) according to  claim 1 , wherein the flexible tapes ( 4 ,  5 ) are comprised of a thermoplastic material. 
     
     
         3 . Hair extension ( 1 ) according to  claim 1 , wherein the flexible tapes ( 4 ,  5 ) of the linear fixing member ( 2 ) are both formed by a network of woven threads, the through holes being determined by the network meshes, the threads being comprised of a thermoplastic material. 
     
     
         4 . Hair extension ( 1 ) according to  claim 1 , wherein proximal ends ( 7 ) of the hair reach the an upper edge of the flexible tapes ( 4 ,  5 ). 
     
     
         5 . Hair extension ( 1 ) according to  claim 1 , wherein the tape and film material are comprised of a transparent material. 
     
     
         6 . Hair extension ( 1 ) according to  claim 5  wherein said material is polyester or polyurethane based. 
     
     
         7 . Hair extension ( 1 ) according to  claim 3 , wherein the network has an overall thickness not greater than 200 μm. 
     
     
         8 . Hair extension ( 1 ) according to  claim 1 , wherein the adhesive fixing layer ( 6 ) is an acrylic based adhesive. 
     
     
         9 . Hair extension ( 1 ) according to, which is  claim 1 , further comprising a weft extension, wherein hairs ( 3 ) are evenly distributed along said linear fixing member ( 2 ). 
     
     
         10 . Hair extension ( 1 ) according to  claim 8 , wherein the hairs ( 3 ) are provided in the form of individual lock-like extension in which the hairs are joined in distinct and separated locks, the proximal ends thereof being equidistant to each other along the linear fixing member ( 2 ). 
     
     
         11 . Hair extension ( 1 ) according to  claim 1 , wherein one or more of said further adhesive layers ( 8 ) comprise a thermosetting glue. 
     
     
         12 . Hair extension ( 1 ) according to  claim 1 , wherein said linear fixing member ( 2 ) comprises, on both opposed sides thereof, a further adhesive layer ( 8 ), on one of said sides, the adhesive layer comprising a thermosetting glue.
