Abstract: The methodd provides for the attachment of extensions or wefts of hair to the naturally growing hair of a person. First, the location of where the extension is to be attached to the person is determined. Then, the hair is parted along that location. The hair along the part is gathered together in small clumps. A crimpable anchor device is located onto each clump of hair. Each anchor device is positioned along the respective hair clump to a position near the scalp of the person. The anchor devices are crimped so as to secure their positions. Then, the extension is sewn to the clumps of hair using needle and thread. The needle and thread pass through the respective clumps at locations between the anchor devices and the scalp. The naturally growing hair is allowed to fall in place so as to cover the points of attachment.
