Make sure the Fast Lashes are thoroughly dry before sleeping or showering. We recommend applying them in the morning. If some lashes come off after sleeping, you can easily reapply them without having to reapply the entire set. In addition if you feel the Fast Lashes sitting after placing them, try applying them slightly higher, about 1/2mm above your own lash roots. Tweeze your Fast Lashes every night for long-lasting beautiful results.
