Which tool is typically used to isolate lashes when applying extensions?

The use of straight tweezers for isolating lashes is favored due to their design, which allows for precision and control when separating individual eyelashes. These tweezers provide a firm grip, enabling the technician to isolate a single natural lash from the surrounding lashes without causing discomfort or damage. Precision in isolation is crucial to ensure that the extension adheres correctly to only one natural lash, which contributes to the overall aesthetic and health of the natural lashes.

While curved tweezers are also commonly used in lash extension procedures, they are more suited for picking up and applying the extensions rather than isolating the natural lashes. Scissors, on the other hand, are not appropriate for isolation as they are meant for cutting rather than delicately manipulating individual hairs. Forceps can be used in different contexts within beauty treatments, but they lack the specific design required for effective eyelash isolation.

Thus, straight tweezers stand out as the most suitable tool for the isolation process in the application of eyelash extensions.
