Abstract: A method for preparing a hair weft for applying to hair of a user. The method may include determining a length of hair weft to produce, measuring the length on a hair weft longer than the hair weft to produce, and cutting a base of the longer hair weft to produce a hair weft having the measured length. The method may further include cutting a double-sided tape to be utilized with the measured hair weft, where the double-sided tape may be composed of a double-sided adhesive film and non-adhesive backing adhered to each adhesive side. A non-adhesive backing may be peeled from the double-sided adhesive film to expose the double-sided adhesive film and the exposed cut double-sided adhesive film may be adhered to the base of the measured hair weft. The hair weft may be applied to a user's hair to form a hair extension.

Abstract: A hair extension kit may include a container configured to include multiple components for installing hair extensions. Within the container may be included a hair weft having a base with hair extending therefrom and double-sided tape configured to have a substantially planar portion. The double-sided tape may have a length of at least three inches and a height of at least one inch. The double-sided tape may be medical grade quality. A hair extension replenish kit may also be provided to include additional supplies to reuse the hair weft provided in the hair extension kit, thereby forming a hair extension system. The hair weft and double-sided tape may be configured such that no additional fasteners are used to secure the hair weft to a wearer's hair.
