There is no universal fill schedule. Yours depends on your own lash cycle and how you treat the set.
Extensions do not fall out because the extension fails — they fall out because the natural lash they are attached to sheds, the way all lashes eventually do. A fill is not a top-up so much as replacing extensions on lashes that have shed and grown back in since your last visit.
Natural lash growth cycles vary meaningfully between people, and so does how gently you treat a set day to day — sleeping position, rubbing, oil-based products near the eyes, and how well you followed aftercare all affect how a set holds up. Anyone quoting you a single number that applies to all clients is simplifying.
A technician removes extensions that have grown out or are sitting awkwardly, cleans the natural lashes underneath, and applies new extensions to fill the gaps. It takes less time than a full set because most of the lash line is still holding.
Noticeable gaps, extensions sitting at odd angles because the natural lash beneath has grown well past them, or lashes that feel heavier and start catching on things are better indicators than a calendar date.
That is a reasonable choice too. Left alone, a set thins gradually as extensions shed with the natural lashes underneath, and eventually there is nothing left to fill — no removal appointment is required if you would rather let it run out on its own, though a proper removal is still the better option if you want to switch services.
