What does longevity refer to in eyelash extensions?

Longevity in the context of eyelash extensions specifically refers to the duration before natural lashes begin to shed. This concept is crucial because it impacts how long the extensions will remain in good condition before requiring a fill or touch-up. Each natural eyelash has its own growth cycle, and as these lashes shed, the extensions attached to them will also fall off. Understanding longevity helps lash technicians provide clients with accurate expectations about the lifespan of their extensions and when they might need maintenance.

The process of natural lash shedding is a normal part of the hair growth cycle, typically lasting around 4 to 6 weeks for a natural lash to complete its cycle. Hence, true longevity in eyelash extensions is tied to how well the extensions adhere during this period and the timing for maintenance appointments.
