What is the typical duration of eyelash extensions before a refill is necessary?

The typical duration of eyelash extensions before a refill is necessary commonly falls within the 4-6 week range. This timeframe is largely due to the natural growth cycle of eyelashes, which generally lasts about six weeks. As natural lashes shed and new ones grow in, some extensions will also fall out, leading to a less full appearance.

During the 4-6 week period, clients are advised to come in for a refill to maintain the fullness and look of their extensions. Regular maintenance helps to ensure the health of the natural lashes and the longevity of the extensions applied. This interval allows for the necessary upkeep without risking damage to the natural eyelashes.

Longer durations, such as 6-8 weeks or over 8 weeks, may result in an uneven appearance or can potentially lead to issues with the health of the natural lash, as too much time without refills might mean that too many extensions have fallen out relative to the growth of new natural lashes. The 1-3 week period typically wouldn’t allow for significant growth and might not justify a refill since clients may still have a number of extensions intact. Therefore, the 4-6 week window is the most suitable for optimal maintenance of eyelash extensions.
