Do false lashes fall off when you cry?

Depends, they usually fall out if the false lashes are like exactly on your lashes. If the glue is too strong, a lash or two might fall out when you take them out. If your careful not to put them directly ON your lashes, they probably won't come off. Putting them close to your lashes but not directly on them is usually safe but, if your natural lashes don't fall out even if you do put false lashes on your real ones, then that's probably fine if they are OK after applying them, no lashes fall out. If it's OK for you, then stick to it! :)
