Offering the highest amount of tack available, the Pro Flex strips have a blue backing (like the blue tape) but they are also dotted with small holes which allow the scalp to breathe. Pro Flex hairpiece tape strips are ideal for extended wear systems and will provide a secure bond up to 4-6 weeks. They come in 12 inch strips that can be cut down to use on hairpieces of any size. Proper scalp cleaning and preparation is essential to getting a long lasting bond. We also sell these in 5 count packs.
