What tool is often used to isolate natural lashes during extension application?

Tweezers are essential tools in the application of eyelash extensions because they provide the precision and control necessary to isolate individual natural lashes. Proper isolation is crucial for the effectiveness of the extension process, as it ensures that each natural lash is treated separately. This careful isolation prevents the risk of adhesive bonding multiple lashes together, which could cause damage to the natural lashes or lead to an undesirable appearance.

Using tweezers, a technician can grasp a single natural lash while keeping adjacent lashes separated. This level of detail is vital to achieve a professional-looking application and to maintain the health of the natural lashes. Other tools, such as scissors, brushes, and combs, serve different purposes in beauty treatments and do not provide the same level of precision needed for isolating lashes during the extension process. Thus, the use of tweezers is fundamental for the successful application of eyelash extensions.
