Installing replacement hair

Abstract

Example methods of installing replacement hair includes installing a fitted scalp mesh over natural hair of a subject experiencing hair loss or hair thinning and pulling from about 80% to 100% of the natural hair beneath the fitted scalp mesh through the fitted scalp mesh as a plurality of natural hair groupings. The method can also include forming a plurality of hair tracks oriented transverse relative to the lateral spacing with multiple natural hair groupings having different starting locations along the individual hair tracks. Individual natural hair groupings of the individual hair track can pass through and are secured by at least two hair fasteners along the individual hair track. Additionally, the method can include installing at least one hair weft on the fitted scalp mesh.

1 . A method of installing replacement hair, comprising:
 installing a fitted scalp mesh over natural hair of a subject experiencing hair loss or hair thinning, wherein the subject has at least 50% natural hair with a majority of the natural hair being at least 2 inches in length;   pulling at least about 60% of the natural hair beneath the fitted scalp mesh through the fitted scalp mesh to an exterior of the fitted scalp mesh, wherein the natural hair is pulled through as a plurality of natural hair groupings having lateral spacing of about 0.5 inch to about 2 inches on average;   forming a plurality of hair tracks along the exterior of the fitted scalp mesh, wherein individual hair tracks are oriented transverse relative to the lateral spacing and include multiple natural hair groupings having different starting locations along the individual hair tracks, and wherein individual natural hair groupings of the individual hair track pass through and are secured by at least two hair fasteners along the individual hair track; and   installing at least one hair weft on the fitted scalp mesh.   
     
     
         2 . The method of  claim 1 , comprising pulling from about 80% to 100% of the natural hair beneath the fitted scalp mesh through the fitted scalp mesh to the exterior of the fitted scalp mesh. 
     
     
         3 . The method of  claim 1 , wherein the hair fasteners include microbeads having a size no larger than about 4 mm. 
     
     
         4 . The method of  claim 1 , wherein the lateral spacing is in alignment with a front hairline of the subject, and wherein hair groupings are also spaced apart in a direction transverse to the lateral spacing at about 1.5 inches or less on average and the hair fasteners are spaced apart in a ventral to dorsal direction. 
     
     
         5 . The method of  claim 1 , wherein the plurality of natural hair groupings is spaced apart laterally at from about 0.5 inch to about 1.5 inches on average. 
     
     
         6 . The method of  claim 1 , wherein the hair fasteners are spaced apart in a direction transverse to the lateral spacing at about 0.5 inch to about 2 inches on average. 
     
     
         7 . (canceled) 
     
     
         8 . The method of  claim 1 , wherein installing the fitted scalp mesh includes shaping the fitted scalp mesh from a flexible mesh material by:
 gathering a portion of the flexible mesh material to form a fitted shape with excess flexible mesh material positioned at an interior of the fitted shape;   stitching the flexible mesh material with the excess flexible mesh being excluded from the fitted shape; and   removing at least 90% of the excess flexible mesh from the interior of the fitted shape to form the fitted scalp mesh.   
     
     
         9 . The method of  claim 1 , wherein installing at least one hair weft includes stitching a top closure hair weft to the fitted scalp mesh at a location over a frontal scalp such that a perimeter of a top closure support of the top closure hair weft extends laterally beyond both apexes of the frontal-temporal recesses of the subject. 
     
     
         10 . The method of  claim 9 , wherein the perimeter of the top closure support extends laterally to about each lower hairline of each temporal scalp. 
     
     
         11 . The method of  claim 1 , wherein installing at least one hair weft includes:
 stitching a top closure support of a top closure hair weft to the fitted scalp mesh at a location over a frontal scalp; and   stitching a finishing weft support of a finishing hair weft to the fitted scalp mesh at a distance from the top closure support from about 0.5 inch to about 2 inches.   
     
     
         12 . The method of  claim 11 , wherein stitching the finishing weft support to the fitted scalp mesh includes using a polymeric water-resistant thread forming a continuous basket stitch. 
     
     
         13 . The method of  claim 11 , wherein stitching the finishing weft support to the fitted scalp mesh includes stitching the finishing weft support to the fitted scalp mesh at a location opposite the direction of hair flow from the finishing hair weft. 
     
     
         14 . The method of  claim 11 , wherein the finishing hair weft includes a polymeric skin flat finishing weft support having a thickness of less than about 0.15 mm. 
     
     
         15 . The method of  claim 11 , wherein the finishing hair weft includes a hand-tied weft support having a thickness of less than about 1 mm. 
     
     
         16 . The method of  claim 1 , wherein the subject is suffering from a hair loss due to a medical condition or medical treatment related to cancer, alopecia, trichotillomania, hormone imbalance, or medication-induced hair loss. 
     
     
         17 - 51 . (canceled) 
     
     
         52 . A system for installing replacement hair, comprising:
 a fitted scalp mesh or a scalp mesh material adaptable to form a fitted scalp mesh sufficient to cover at least a majority of the natural hair of a subject, wherein the fitted scalp mesh has openings sufficient to pull through about 80% to 100% of the natural hair from beneath the fitted scalp mesh to an exterior of the fitted scalp mesh in natural hair groupings spaced apart laterally at from about 0.5 inch to about 2 inches on average and also spaced apart in a direction transverse to the lateral spacing at about 0.5 inch to about 2 inches;   a top closure hair weft having a size sufficient to laterally cover a front hairline of a subject at the frontal scalp and which extends laterally beyond both apexes of the frontal-temporal recesses of the subject; and   a plurality of finishing hair wefts adapted to extend outward from the top closure hair weft along the fitted scalp mesh.   
     
     
         53 . The system of  claim 52 , further comprising a plurality of microbeads having a size of less than about 4 mm. 
     
     
         54 . The system of  claim 52 , wherein the top closure hair weft extends down each temporal scalp covering substantially a front hairline of the subject from ear to ear. 
     
     
         55 . The system of  claim 52 , wherein the finishing hair weft includes a polymeric skin flat finishing weft support having a thickness of less than about 0.15 mm, and wherein the polymeric skin flat finish weft support is devoid of adhesive. 
     
     
         56 . (canceled) 
     
     
         57 . The system of  claim 52 , wherein the finishing hair weft includes a hand-tied weft support having a thickness of less than about 1 mm.
