Walker Tape C-22 Solvent Remover Spray is the best!
QUICK REMOVER & SAFE: Easily remove the adhesive and tape on hair systems.
Spray the solvent directly on the glue/tape area, and leave for 1 to 5 minutes, depending on the type of adhesive used and how long the hairpiece was fitted. Wipe with a soft cloth or cotton wool and wash the hair system.
