Remove and re-apply tape extensions
Tape extensions stay in your hair for about 8 weeks, then you have to remove and re-apply them. For that you would need remover fluid and new tapes either in a roll or pre-cut tapes.
How to re-tape extensions:
Pull the old tape off the extension strand and remove residue with remover fluid. Attach the new tape onto the strand – done. Now you can re-apply the strand to your hair.
