Human hair wefts are hair extensions made from human hair instead of synthetic fiber. Hair extensions add fullness and length to one's own natural hair. Human hair wefts should be made from hair that has not been processed in any way or colored.
The majority of human hair wefts are sourced from Asia, most frequently India, China and Korea. As an export economy, the selling of human hair is growing in Asian regions at a rate of 10 to 30 percent a year. There are several methods of attaching human hair wefts, such as clip-in, bonding, micro loops and tracking.
