How long do individual eyelash extensions last?

Individual eyelash extensions last anywhere from 3-5 weeks (before a fill is needed) depending on your hair growth cycle and how well you take care of them.  Everyday you shed 1-4 eyelashes but you don't really notice this unless you are wearing eyelash extensions. After about  3-5 weeks you will notice some gaps in your eyelashes and need eyelashes reapplied on the areas where they have grown or fallen off. The other way eyelashes come off is the wear and tear of life.  Make them last longer by avoiding: mascara and eyelash curlers ( you won't need them anyways ), running water over your eyelashes in the shower,  rubbing your eyes,  sleeping on your face, and pulling at eyelashes.
