Sensi-Tak by Walker Tape is a very low residue hair tape adhesive, which is popular for use on polyurethane due to its easy clean-up. Great for people who need more than a day to day, yet not looking for the longest adhesion hold either. This is a popular type of tape because many people re-apply their hair replacement systems daily or within a week. Sensi-Tak can last up to 2 weeks and works great on all hair systems and hairpieces.
