Artificial hair integrations, more commonly known as hair extensions, hair weaves, and fake hair add length and fullness to human hair. Hair extensions are usually clipped, glued, or sewn on natural hair by incorporating additional human or synthetic hair. These methods include tape-in extensions, clip-in or clip-on extensions, micro/nano rings, fusion method, weaving method, and wigs.
Tape-in hair extensions last from four to eight weeks and the hair can be gently combed and washed while wearing the extensions. In addition, the extensions need to be treated with specialized shampoos, conditioners and styling products to keep them in top condition. The extensions can be taken off easily by the application of glue remover and can be easily installed by using liquid adhesive or glue tape.
Clip-in weaves, also known as clip-in hair extensions, can be integrated into natural hair to add length and volume. The clip-in hair extensions most commonly come in as a long strand of one contoured piece that can be cut into multiple layers for creating separate layers on a user’s head. When the hair is purchased it often comes with clips, which are sewn into the hair. It is also possible to buy the hair (in bundles) and the clips separately; the clips can then be sewn on by the purchaser or by a stylist.
