How often should eyelash extensions be refilled or maintained?

Eyelash extensions should generally be refilled or maintained every 2 to 4 weeks, depending on the individual's natural lash shedding cycle. This timeframe aligns with the natural growth and shedding phases of the client's lashes, which typically occurs on a cycle that can last anywhere from 28 to 60 days.

As natural lashes grow and shed, some extensions will fall off with them, leading to gaps in the lash line. Regular maintenance within this 2 to 4 week window ensures that the lash line remains full and that the extensions are replaced as needed. This practice not only enhances the appearance of the lashes but also helps avoid any stress on the natural lashes, promoting healthy lash growth.

In contrast, refilling every week may be excessive for most clients, as their natural lashes may not shed quickly enough to warrant such frequent touch-ups. Refills every month could also risk a less polished look, as clients by then may have lost significant numbers of extensions. On the other hand, maintaining lashes every 6 to 8 weeks would likely result in a noticeable degradation of the lash set, as many extensions would have fallen off and not been replaced in a timely manner.
