Wig glue causing cancer? If that was true, every single actor who ever appeared in a "costume drama" where a wig had to be worn would have "forehead cancer", a particular type of cancer, this woman, who works in healthcare insurance, has never heard of. I mention this only because 1) I've never heard of forehead cancer; 2) movies take 6-12 weeks to finish; 3) many of the women on this forum would have this cancer because many of the women here still glue down their units.
I see you are a "newbie" here. Welcome. There was a discussion about forehead cancer and wig glue a few years ago. You may want to read it as a piece of reference. That is not the issue of my original post, but rather that of pulling my hair off my face. Incidentally, I never said I glued my unit down. And, thanks to hereditary and stress, I do not have enough hair in the front to have any leave-out. BTW, clips can pull out your hair as well.
Thank you all for your suggestions. I will work on making my unit's hairline better and do some ventilating.
