The Weft Hair is an extension of the hair designed to make one's hair appear thicker or longer. This type of hair piece is particularly popular among teenagers and young adults, though they are accessible for most ages. Both synthetic hair pieces as well as human hair pieces are used to make hair wefts. It is a collection of hair strands sewn onto a super-thin cloth strip ready for the stylist to work into the hair. Weft Hair is very effective and suitable.
