What role does a pre-treatment play in the application process?

A pre-treatment is essential in the application process of eyelash extensions as it prepares the natural lashes for better adhesion. By cleansing and priming the lashes, the pre-treatment removes any oils, makeup residue, or other impurities that could interfere with the bonding process of the adhesive. This optimal preparation ensures that the extension adheres more effectively to the natural lashes, which is crucial for the longevity and overall quality of the eyelash extensions.

Other options, while they might seem relevant, focus on aspects not directly related to the primary purpose of a pre-treatment. For example, while enhancing the durability of extensions and increasing color retention of extensions are important considerations in the overall eyelash extension process, they are typically achieved through the quality of the adhesive used and the aftercare provided, rather than through the pre-treatment itself. Thicker lashes are not achieved through a pre-treatment, but rather through the choice of extension length and volume applied during the procedure. Thus, the role of a pre-treatment is specifically to create optimal conditions for a strong and lasting bond between the natural lash and the extension.
