Weft hair extensions are not new, so you can be purchase them from beauty supply stores. The extensions are available in either synthetic fiber or 100% human hair. Wefts are strands of hair that are woven into long, cloth bands. The bands, not the actual extension hair, are what you attach to your natural locks.
Wefts are applied to your hair with a special type of latex glue made specially for hair extensions. Give your hair the length and body you want by applying weft hair extensions.
