What could happen if you apply too long lash extensions on a natural lash?

Applying lash extensions that are too long for a natural lash can lead to breakage of the natural lashes. When an extension is excessively heavy or long compared to the natural lash, it can cause stress on the natural lash's structure. This can result in the natural lash not being able to support the weight of the extension, leading to potential damage. This kind of stress can weaken the natural hair, making it more prone to breaking or falling out prematurely.

In contrast, the other options do not accurately reflect the consequences of using overly long extension lashes. Increased growth rate does not occur as a result of having longer extensions; the growth cycle of natural lashes remains the same regardless of the extensions. Similarly, the idea of faster shedding does not stem from the length of the extensions themselves, but rather from the health and integrity of the natural lash. Therefore, protecting the health of natural lashes is crucial when selecting the appropriate length of extensions.
