What is a potential result of using too much adhesive during eyelash application?

Using too much adhesive during eyelash application can lead to damage of the natural lashes. Excessive adhesive increases the weight on the natural lashes, which can strain them and cause breakage or premature shedding. This damage can result in sparse eyelashes and can even lead to traction alopecia if the natural lashes are unable to support the weight of the extensions over time.

The options regarding eyelash longevity and appearance suggest effects that are not aligned with the proper techniques for application. For instance, while it might seem that more adhesive could lead to longer-lasting extensions, in reality, overuse can lead to problems that diminish longevity due to the natural lashes' compromised health. Additionally, an increase in volume may briefly result from clumping due to excess adhesive; however, this is not a desired outcome as it also increases the risk of damage. Lastly, the assertion that there would be no impact on the lashes is incorrect, as the consequences of using too much adhesive are clearly detrimental to the integrity of the natural lashes.
