What does the term "longevity" refer to in the context of eyelash extensions?

In the context of eyelash extensions, "longevity" primarily refers to the duration that the extensions remain intact and adhere to the natural lashes before they start to shed and require touch-ups. This consideration encompasses several factors such as the quality of the adhesive used, the application technique, and the aftercare provided by the client. Understanding longevity is essential for both the technician and the client, as it directly impacts how often maintenance appointments will be necessary, which affects client satisfaction and the overall success of the eyelash extension service.

While the natural growth speed of eyelashes and the durability of the extensions are relevant to the longevity concept, they do not encapsulate the full range of meaning related to how long the extensions stay effective and aesthetically pleasing. The required length of the extensions pertains more to the dimensions of the lashes rather than their lasting power on the natural lashes. Thus, the focus on the timeframe before shedding emphasizes the practical aspect of eyelash extensions and their upkeep.
