Eyelash enhancer without lash loss?

I already have pretty long lashes but decided to try the Revlon Grow Luscious mascara, which is supposed to lengthen/thicken/etc., and it did the job but eventually I noticed a couple lashes would fall out here and there when removing make up or slightly rubbing my eye.. What is the best product for enhancing lashes without the lash loss (or any other unwanted side effects)??
