About the method BEAUVOIR Professional Tape-In hair extensions are the easiest to remove and reapply while achieving the most secure application to the hair. After the backing of the one-sided polyurethane tape has been removed, the weft is attached to the hair. In order to "sandwich" the hair, the weft with the hair connected is pulled upward and a new weft is put to the other side of the tape. A single panel secured with single-sided tape may be necessary for clients with exceptionally thin hair, particularly around the temples and side of the head. Beauvoir Professional: This blend combines 50% single donor virgin hair with 50% high-grade remy cuticle hair. Our Single Donor Virgin hair is sourced from just one donor, guaranteeing unparalleled quality. Before cutting, the hair is carefully braided while it’s still on the donor, ensuring that when it’s sent to the factory, the natural cuticle direction is evident. This eliminates the need for the damaging cuticle alignment process. Our remy cuticle hair is the highest grade remy cuticle hair available. The fusion results in hair that boasts 50% more cuticle integrity than standard extensions, ensuring longevity, enhanced appearance, and superior washability.
