This is a common issue. It’s easier and less time consuming to do a touchup than a a full re-bond. But it can be done. A key is to clean the scalp properly so you can get a good bond. Take a clean cloth--preferably a micro-fiber towel--and dip it in 91% (or near that percentage) rubbing alcohol from your local drug store. Wipe the area that you want to re-attach until it’s clean. Any left over glue or tape residue is going to compromise the attachment. Then apply the tape or the glue to the area. I know it’s tricky at first. It takes some ‘getting used to’ in order to coordinate your hand with the area you want to work with. It helps to put a couple fingers down on the scalp to give you a ‘point of reference.’ Another thing you can do is use ‘Got 2 Be Glued Spiking Glue’ for the attachment. It’s a mild attachment but the beauty of that is that it’s water soluable so it’s an easy clean up while you’re ‘getting the feel’ of working on the back of your hear. Good luck!
