You could try, perma-lash adhesive, by ANDREA.

I have been told that cancer patients use this because it is so hard to get off. I don't know about that. However I can tell you from personal experience that it is VERY hard to get off. In the link I attached it says that it lasts 6 weeks.

I think you can buy it seperately, if not it is part of the indervidual lash kit.
