It is impossible to give a general answer to this question and would be dishonest. The durability of artificial eyelashes is different for every person and depends on many different factors:
– How do you handle the eyelashes? If you touch them often or rub your eyes, the lashes will not last as long.
– How well and thoroughly do you follow the instructions for aftercare?
– What is the natural growth cycle of your lashes?
– What is your makeup routine?
Normally, the artificial lashes fall out during the natural hair change of your own lashes. As 2-5 natural lashes fall out every day, you need to have your lash extensions filled up to ensure that the lashes continue to look evenly thick.
