Many clients still not sure what lash cycle is or even know that our nature lashes shed over time. Everyone has different lash life cycle and even each individual lash has its own life cycle. This is something your lash tech can not tell by her bare eyes. But you, as a client, need to understand that our nature lashes grow and shed. So after a week or so, the extensions grow out with the nature lashes and sometimes they become too heavy and turn downwards.
It is better that you go back to your lash tech every 2 weeks to have it re-touched or filled or even removed if necessary. It all depends on your condition. It is actually not saving money when you plan to get a fill after 3rd week since most lash tech will tell you that you need to remove them because more % of your lashes are grown out like what it shows in the photo here. It is harder for lash techs to fix them for you at that point. So as a client, you must understand sometimes it is not that your lash tech doesn’t want to in-fill your lashes or charges more, its because technically, it is harder and much more work if they do in-fills.
