I replied to your question on the other thread there.... my experience has been the opposite to yours...got less itchiness as time went on rather than more frequent....which would lead me to guess that it may be a sensitivity to whatever bonding product you are using there? Maybe try changing to a different one or ...just temporarily ... try using `Got2b`glued for a few days...yes it won`t give a complete bond right to the very edge, but it WILL hold 90-95% of the rest of the system in place for you [and it`s cheap to buy and easy to rinse out/off] ...you can use a little normal glue or tape at the front in case it lifted/ became free.....just to see if your nape irritation settles down...... hope that helps...must be pretty uncomfortable and the danger is if you really go at it hard with your finger nails and break the skin while itching it, then you may get more` problems `...... from what you say it sounds like it`s the bonding product, but of course, I may be totally wrong.....
