Hair extensions with increased durability and longevity

Abstract

An improved hair extension includes a base portion that is oblique with respect to a horizontal reference. The hair strands coupled to the base portion define an oblique (e.g., non-perpendicular angle) with respect to the base. In this configuration, the hair strands fall vertically while the base is angled. This prevents undue stresses in the hair and in the base due to bending when traditional hair extensions are placed in a tilted manner and reduces unwanted bumps due to these inflection points.

What is claimed is: 
     
         1 . A method of installing a hair extension section at an installation site of a wearer, the hair extension section comprising a base portion comprising a plurality of extension strands extending from the base portion at an oblique angle relative to a length of the base portion, the method comprising:
 selecting the installation site;   sectioning, at the installation site, natural hair of the wearer at the oblique angle such that an upper section of natural hair is parted from a lower section of natural hair by an angled path that is angled with respect to a sagittal axis of the wearer;   select the base portion from a set of base portions;   preparing an adhesive for attachment of the base portion to the lower section of natural hair;   aligning the base portion of the hair extension section with the angled path;   placing the prepared adhesive against the lower section of natural hair to affix the hair extension section against the lower section of natural hair such that the plurality of extension strands fall parallel to strands of natural hair of the lower section of natural hair; and   causing the adhesive to affix to the hair extension section against the lower section.   
     
     
         2 . The method of  claim 1 , wherein the base portion comprises a linear section and an angled section joined at a junction. 
     
     
         3 . The method of  claim 2 , wherein aligning the base portion of the hair extension section with the angled path comprise aligning the angled section of the base portion with the angled path. 
     
     
         4 . The method of  claim 1 , wherein causing the adhesive to affix to the hair extension comprises applying heat to the base portion. 
     
     
         5 . The method of  claim 1 , wherein the oblique angle is between thirty degrees and sixty degrees. 
     
     
         6 . The method of  claim 1 , wherein preparing the adhesive for attachment comprises removing a backing layer of adhesive formed on the base portion. 
     
     
         7 . The method of  claim 1 , wherein preparing the adhesive for attachment comprises heating the base portion. 
     
     
         8 . The method of  claim 1 , wherein preparing the adhesive for attachment comprises applying pressure to the base portion. 
     
     
         9 . The method of  claim 1 , wherein selecting the base portion from the set of base portions comprises selecting a respective base portion based on a respective oblique angle at which a respective plurality of extension strands extend from the respective base portion. 
     
     
         10 . The method of  claim 1 , wherein the plurality of extension strands comprise human hair with a common cuticle scale direction. 
     
     
         11 . A method of installing a hair extension section at an installation site of a wearer, the hair extension section comprising a base portion comprising a first section and a second section and a plurality of extension strands extending from at least one of the first section or the second section at an oblique angle relative to the respective section of the base portion, the method comprising:
 sectioning, at the installation site, natural hair of the wearer at the oblique angle such that an upper section of natural hair is parted from a lower section of natural hair by an angled path that is at least partially angled with respect to a sagittal axis of the wearer;   aligning at least one of the first section or the second section of the base portion of the hair extension section with the angled path;   placing the base portion against the lower section of natural hair to affix the hair extension section against the lower section of natural hair such that the plurality of extension strands fall parallel to strands of natural hair of the lower section of natural hair; and   affixing the hair extension section against the lower section at the installation site.   
     
     
         12 . The method of  claim 11 , wherein at least one of the first section or the second section comprise a curved path part. 
     
     
         13 . The method of  claim 11 , wherein the first section defines a first angle with respect to the sagittal axis and the second section defines a second angle with respect to the sagittal axis, the second angle different from the first axis. 
     
     
         14 . The method of  claim 11 , wherein affixing the hair extension section against the lower section at the installation site comprises sewing. 
     
     
         15 . The method of  claim 1 , wherein affixing the hair extension section against the lower section at the installation site comprises applying a keratin-based glue to at least one of the hair extension section or the installation site. 
     
     
         16 . A hair extension section comprising:
 a base portion comprising:
 a first section; and 
 a second section; and 
   a plurality of extension strands extending from at least one of the first section or the second section at an oblique angle relative to the respective section of the base portion.   
     
     
         17 . The hair extension section of  claim 16 , wherein the base portion comprise fabric. 
     
     
         18 . The hair extension section of  claim 16 , wherein the plurality of extension strands comprises natural hair with a common cuticle scale direction. 
     
     
         19 . The hair extension section of  claim 16 , wherein the based portion comprises a keratin based adhesive. 
     
     
         20 . The hair extension system of  claim 16 , wherein the oblique angle is between thirty and sixty degrees.
