Extenda-Bond has been a favorite in the industry for quite some time. You probably know it by its distinctive holes which allow the scalp to breathe. As part of our maximum wear category (2-4+ weeks), It’s one of our longest holding tapes. You can expect a 4 week hold from this acrylic adhesive. It also has a very dull finish that is virtually invisible under the unit. It’s flexibility makes it extremely comfortable to wear.
