Interlocking Hair Extensions

Abstract

An interlocking hair extension is provided. The hair extensions are designed to rotate around an axis running the length of the piece and lock into place using alternating, offset teeth and magnets. The unique arrangement provides for hair extensions that can be used in both permanent and semi-permanent installations and that can be applied by a user without assistance from a third party.

What is claimed is: 
     
         1 . A hair extension weft comprising:
 a support strip;   at least one magnet attached to said support strip;   engaging members provided along an edge of said support strip; and   hair affixed to said support strip;   wherein said engaging members extend outward from said edge of the support strip, said weft being magnetically connectable with another weft of similar design following alignment of said engaging members of each weft.   
     
     
         2 . The hair extension weft of  claim 1  wherein said hair is sewn onto said support strip. 
     
     
         3 . The hair extension weft of  claim 2  wherein said hair comprises human hair. 
     
     
         4 . The hair extension weft of  claim 1  wherein said at least one magnet is a bar magnet running the length of said support strip. 
     
     
         5 . The hair extension weft of  claim 1  wherein said at least one magnet comprises discrete magnets spaced at intervals along the length of said support strip. 
     
     
         6 . The hair extension weft of  claim 5  wherein said magnets are encased in a polymer coating. 
     
     
         7 . The hair extension weft of  claim 5  wherein said magnets are encased in small sacs affixed onto said support strip. 
     
     
         8 . The hair extension weft of  claim 1  wherein said engaging members comprise teeth affixed to said edge of said support strip in a gapped arrangement. 
     
     
         9 . The hair extension weft of  claim 8  wherein said teeth have an upward tilt away from the horizontal plane of said support strip and are affixed along an upper portion of said edge of said support strip. 
     
     
         10 . The hair extension weft of  claim 10  wherein the distance said teeth extend away from the horizontal plane of said support strip is less than the thickness of said weft. 
     
     
         11 . A hair extension weft comprising:
 a support strip having a lower portion, an upper portion, and an upper edge;   at least one magnet attached to said upper portion of said support strip;   engaging members provided along said upper edge of said support strip; and   hair affixed to said lower portion of said support strip;   wherein said engaging members extend outward from said upper edge of the support strip, said weft being magnetically connectable with another weft of similar design following alignment of said engaging members of each weft.   
     
     
         12 . The hair extension weft of  claim 11  wherein said hair is sewn onto said support strip. 
     
     
         13 . The hair extension weft of  claim 11  wherein said at least one magnet is a bar magnet running the length of said support strip. 
     
     
         14 . The hair extension weft of  claim 11  wherein said at least one magnet comprises discrete magnets spaced at intervals along the length of said support strip. 
     
     
         15 . The hair extension weft of  claim 11  wherein said at least one magnet is encased in a polymer coating. 
     
     
         16 . The hair extension weft of  claim 11  wherein said engaging members comprise teeth affixed to said upper edge of said support strip in a gapped arrangement. 
     
     
         17 . The hair extension weft of  claim 16  wherein said teeth have an upward tilt away from the horizontal plane of said support strip and are affixed along an upper portion of said edge of said support strip. 
     
     
         18 . The hair extension weft of  claim 17  wherein the distance said teeth extend away from the horizontal plane of said support strip is less than the thickness of said weft. 
     
     
         19 . The hair extension weft of  claim 11  wherein said at least one magnet comprises discrete magnets spaced at intervals along the length of said support strip and said engaging members comprise teeth affixed to said upper edge of said support strip in a gapped arrangement, wherein said teeth have an upward tilt away from the horizontal plane of said support strip and are affixed along an upper portion of said edge upper edge of said support strip wherein the distance said teeth extend away from the horizontal plane of said support strip is less than the thickness of said weft. 
     
     
         20 . A method of placing interlocking wefts of hair extensions on a person comprising:
 creating a seam line in the hair of a person's head;   placing a bottom weft of hair along the length of said seam line;   pulling a width of natural hair from above said seam line and placing said width of natural hair over said bottom weft;   placing a top weft of hair on top of said bottom weft and said width of natural hair;   aligning engaging members along corresponding edges of said top and bottom wefts; and   magnetically affixing said top and bottom wefts to each other;   wherein said top and bottom wefts are securely held to said width of natural hair via magnetic forces and the frictional resistance of said natural hair within said engaging members.
