How often should clients have their eyelash extensions filled?

Clients should have their eyelash extensions filled every 2 to 4 weeks to maintain a full and natural look. This time frame allows for the natural lash growth cycle, which typically sees natural lashes shedding and renewing themselves every 6 to 8 weeks. During this period, some extensions may fall out along with the natural lashes, creating gaps. Regular fills within the 2 to 4-week range help ensure that these gaps are filled and that the extensions continue to look their best.

Scheduling fills within this recommended range also maximizes the appearance and retention of the extensions, while minimizing the risk of damage to the natural lashes, which could occur with longer intervals between fills. This timeframe offers clients the best combination of maintenance and aesthetics, supporting the longevity of their eyelash extensions.
