Try sleeping on your back if you have lash extensions. Sleeping on your face or side can cause your lash extensions to fall out sooner due to them getting snagged on your bedding, or just the general rubbing against your pillow, if you are a side sleeper then invest in a silk pillowcase which will help lashes to slide rather than getting caught on cotton cases.
Also if you are a side sleeper you may notice you loose lashes quicker on the side you tend to sleep on. This is normal and the only way to avoid this is sleep on your back, easier said than done I know ?
