How often should eyelash extensions be refilled to maintain their look?

The best interval for refilling eyelash extensions is every 2 to 4 weeks. This timeframe allows for the natural growth cycle of eyelashes to take place without leaving any gaps or resulting in an uneven appearance. As natural eyelashes shed, the extensions attached to them will also fall out, making regular refills necessary to maintain a full and lush look.

Different factors can influence this schedule, such as the person's natural lash growth rate, their lifestyle, and how well they care for their extensions. Generally, refilling every 2 to 4 weeks is considered optimal to keep extensions looking their best and to ensure that the lashes remain healthy and intact without causing stress to the natural lashes.

Other suggested timeframes, such as every week, every month, or every 5 to 6 weeks, may not adequately consider the natural shedding process and may lead to a less desirable aesthetic. Weekly refills could be overly frequent and impractical for most clients, while extending the refill period too long may result in an uneven and sparse appearance.
