I'm wearing the full caps now all the way to the nape so that I don't keep any of my own hair anymore. I really like how this looks on day one of the attachment, but I am finding that I have to reattach the "hairline" of the nape by the next day---because of a dirty line that the glue leads to. Anyone have any ideas on how to avoid this? If I didn't sleep on my back it would help, but I'm not willing to sacrifice that. Unfortunately, the hair needs to be the shortest at the nape in order to achieve the look I want.
