What is the purpose of an eyelash extension bonder?

The purpose of an eyelash extension bonder is to increase retention and enhance bond strength between the natural lashes and the extensions. A bonder works by creating a strong adhesive connection, ensuring that the extensions adhere well and last longer. This is crucial for maintaining the look of the extensions over time, as it helps minimize the chances of premature shedding or loosening.

In the context of the other options, providing color to the extensions is not the function of a bonder; instead, it serves as an adhesive enhancer. Similarly, while there are products designed to safely remove extensions, that is not the role of a bonder. Lastly, cleaning the natural lashes is a separate step in the lash extension process that involves different types of products, typically cleansers or shampoos specifically formulated for lash care. Therefore, the primary role of a bonder is indeed to enhance the longevity and strength of the bond between the natural lashes and the extensions.
