i've had customers having to come in to get lashes put on every weekend, because they were previously wearing those "individuals" that are glued on with hair glue... and they lost chunks of their own lashes! since some of the glue bonds to the eyelash hairs, it may rip them off! i've seen it happen to alot of people. i don't don't think it's worth it, even if they stay on for a long period of time. not to mention the possibility of it getting into your eye! umm going to the ophthalmologist for an allergic reaction to a foreign substance can be really expensive! NOT WORTH IT PEOPLE!
