Yes...ive been trying it for 2 days as I received my hair piece in the post on Thursday. I've never tried anything like this and had high expectations after watching so many you tube videos. It's been a nightmare. Ghostbond was suggested by my supplier. I went to work Friday and am a commercial cleaner so I do sweat a bit but nothing extreme. Within 4 hours the glue had broke down into a white sticky mess. In the end I had to peel the hairpiece off and thankfully had my cap with me. Cleaned it all up, prepared my scalp again and reapplied yesturday evening. Woke up and again it was coming away slightly around the hairline so I glued it back. Went into town and it's hardly a boiling hothe day but the glues done the same thing agsin..turned to mush and my piece is falling offrom and my scalp is very wet. I don't even sweat much so how people say ghostbond lasts for weeks I don't know.. it's usless on me. I'm screwed till I can find an alternative!
