Eric ...seems like factory-residue might be the issue here... which is why it`s best to give your new system a wash or two before cut-in....to ensure the lace is `clean`... you could try adding a little layer of glue on at the front there....my only concern is that it may not hold for too long if there actually IS residue still on the lace .... your wife can easily help you smear a little glue onto the tape at the back [assuming the lace has come free from the tape and the tape is still `good`against the skin].......what you could do is give the `free`lace a gentle wipe with a clean cotton cloth moistened with alcohol ..might help `clean`it a bit,but don`t soak it ..just a light wipe ---you can `clip`the loose area up `out of the way` with something like a clothes peg --simply clip the hair to the hair behind it..then apply a thin layer of glue at the front, on top of the existing glue....MAKE ABSOLUTELY SURE you allow the glue to go practically dry before pressing the lace down on it.....you can speed it up by aiming warm air from a hair dryer onto it --a little bit smeared onto the tape at the back should help hold your system back on again.... try that and see how you get on....it`s just a little touch-up which may get you through until your next appointment....if it doesn`t , you`ll have to go back to the stylist ...wouldn`t take her long anyways....probably 20 minutes tops to replace your bond....my feeling is this sounds like factory residue problem.
