How can eyelash extensions affect natural lashes if misapplied?

Eyelash extensions can indeed cause lash breakage if they are misapplied. This can occur due to several reasons, such as using the wrong type of adhesive, applying extensions that are too heavy for the natural lashes, or improper placement. When an extension is too heavy, it can put excessive stress on the natural lash, leading to breakage or premature shedding. Additionally, if the extension is poorly bonded, it can create tension that disrupts the natural growth cycle of the lashes. Proper technique, product selection, and ensuring the health of the natural lash are essential to prevent damage.

In contrast, the other options do not accurately reflect the potential consequences of misapplied eyelash extensions. While they may enhance natural growth when applied correctly, they do not inherently promote growth if misapplied. Instead, they can hinder the natural lash’s health. The idea that they provide no effect on natural lashes is also misleading, as their application will always interact with the natural lashes in some way. Lastly, eyelash extensions cannot change a client's eye color, as that is a physical characteristic unrelated to lash application.
