How Long Do Lash Extensions Really Last?

Lash extensions are bonded to your natural lashes, which means their lifespan is tied directly to your own growth cycle. Each natural lash grows, rests, and sheds on a 6–8 week cycle, so as your lashes shed naturally, the extensions go with them.

Fills every 2–3 weeks keep a set looking consistently full by replacing what's been shed. Going longer than that between fills is the single biggest factor in a set looking sparse.
