A hair extension, according to one embodiment, includes a section of hair having front and back sides, and an adhesive layer attached to the back side of the section of hair. The section of hair is affixed together at one lengthwise end by a pliable polymer. The affixed-together end of the section of hair is retained within the polymer, and the polymer is exposed widthwise across the section of hair on the section of hair's front and back sides. The polymer on the front side of the section of hair is sized and shaped to facilitate attachment of an adhesive layer that may be separately applied by a user or stylist. The adhesive layer on the back side of the section of hair facilitates attachment of the section of hair to natural hair of a user. Alternatively, adhesive layers may be pre-attached to both sides of the section of hair.

A method for hair-braiding that includes making a lace closure is described. The one-stranded method includes making a lace closure with synthetic hair, parting locks of the synthetic hair from the lace closure into sections of hairs, pulling a loop of a crochet over a hook, attaching the sections of hairs to the hook, pulling the hook with the attached sections of hairs through the loop of the crochet, wrapping the sections of hairs around the crochet, tying a portion of the sections of hairs around the crochet, and applying heat to the wrapped sections of hairs to heat shrink the sections of hairs.
