http://www.closettherapyblog.com/blog/eyelash_extensions/index.html Individual eyelashes are glued onto your existing eyelashes. You can choose how full or long you want them, and as your natural eyelashes fall out, the extension attached falls out also. They last up to two months. I would love to have a set of falsies that could last up to 2 months! The cost puts me off, however. I found a nearby salon that will do it for $100, which surprises me considering it's a nice salon and everyone else is charging around $250. Maybe their pricing list online was outdated.
