Abstract: A method is provided for attaching a hair extension to a recipient's hair. The method comprises defining an anchoring structure for receiving attachment of the hair extension; positioning the hair extension adjacent to the anchoring structure; employing a hair extension attachment apparatus to attach the hair extension to the anchoring structure; wherein the employment includes manipulating a user manipulable hand member of the apparatus to position a shield mechanism between the recipient's scalp and the fastener as the fastener is being crimped; and to crimp a fastener to attach the hair extension to the anchoring structure. An apparatus is provided for attaching a hair extension to the recipient's hair. The apparatus comprises a mechanism for crimping a fastener to attach the hair extension; and a shield mechanism for preventing the fastener from contacting the recipient's scalp as the fastener is being crimped.
