A weave involves attaching wefts, or tracks, of store-bought hair to your own hair to add extra body and length. The hair used for a weave may be human or synthetic, and it's attached by way of needle and thread stitching or

bonding glue. Sewing in a weave is a long process that should be done by an experienced stylist, so if you want a weave right away, the quicker option is to glue one in yourself in just a few minutes' time.
