Abstract: The invention provides a scalp hair strand/supplemental hair fiber strand attachment structure and method, which enables the scalp hair strand (1) to be firmly tied to the supplemental hair fiber strand (2) without giving a pull to the scalp from which scalp hairs grow, doing damage to the scalp and inflicting pain on the wearer while at work, with ease, in very short work time, and with no need of expertise. The tying portion of the scalp hair strand (1) to the supplemental hair fiber strand (2) is tied up via a binder or bonding adhesive and the tying portion (3) of both strands is further wrapped around with a tape (4) having an adhesive.
