Semi-permanent eyelash glue is the question... I've been using the Marvelash glue, but I really don't think too much to it at all, 2/3 the lashes last 1 week maybe. Please help if any of you know what's the best glue about to use?! Also a friends mentioned that there's a hair extension glue on the market that is also very good for lashes, but don't know what the make is :?: heeelp xo
