Virgin Machine Weft Hair Extensions Brazilian 100% Human Hair Sew In Bundles Off Black (#1B)

Hair wefts, also known as machine wefted hair extensions, are a type of hair extension construction method. They involve the use of a machine to sew or weave human hair strands together to create a long, continuous track of hair. In the machine hair weft extension process, the hair strands are aligned and evenly distributed before being sewn or machine-woven onto a thin strip of fabric or lace. This strip is referred to as the weft, which serves as the foundation of the hair extension. It's worth noting that hair wefts require professional installation by a trained stylist to ensure proper application and minimize the risk of damage to the natural hair. They can be attached to the natural hair using methods such as sewing, bonding, or clipping, depending on personal preference and the expertise of the stylist.
