Invisibond has a light hold strength!. Best used for short term bond time. Use Invisi-Bond for a Light- hold - safe for skin. Will not bond to cloth/fabric wig caps. Must use tape around the perimeter of the wig in order to get best bond possible. If you bond and allow wig/hair piece to come in contact with Invisibond, it will not only get a poor bond but also difficult to clean/remove from wig cap. Using tape to protect wig cap is best choice. Adhesive is pressure sensitive. This means once you have bonded hair system to head you will need to rub back and forth the bonded area. This helps create a secure bond. I like to use the back of my hair brush to rub back and forth.
