Hair extension attachment

Various embodiments of wefted hair extension attachments include attachment strands extending from the weft edge of the attachment. These attachment strands are braided or intertwined directly into the braids formed in the native hair of the wearer as those braids are being formed, without need for additional sewing and thread, adhesives, or other attachment apparatus. Use of the present hair extensions saves considerable time for both the person who is installing the hair extensions on the wearer, as well as for the wearer. This is due to the combining of the braiding of the wearer's native hair into an attachment braid or braids, and the securing of the hair extension(s) to the braid(s), in a single step, rather than requiring the braids to be formed and then attaching the hair extensions in a subsequent step, as is accomplished conventionally.
