I have been using this tape (1" x 3" strips) for almost 10 years on sides and back thinskin perimeter. A while ago, I noticed that wherever this tape has been touching, there is a noticeable depression in my scalp.

It's weird. Has anyone experienced this?

Anyone?
As an experiment, I put a small piece on my forehead at bedtime and in the morning, there was a little "creater" where the tape was. It doesn't happen with blue lace tape.
