What type of tweezers are used to hold the side lashes away from the main isolated lash?

The correct answer identifies straight tweezers as the type that is effectively used to hold side lashes away from the main isolated lash during the application of eyelash extensions. Straight tweezers provide a stable grip and allow the technician to maneuver around the isolated lash easily. This is crucial for ensuring precision and cleanliness in the application process, as it prevents unintended contact with surrounding lashes and helps the technician maintain focus on the precise area they are working on.

While curved tweezers can also be useful in certain circumstances, they are typically designed for different tasks, such as applying extensions or picking up lashes at difficult angles. Pointed tweezers have a sharper tip and are often suited for isolation or picking up smaller items, but they lack the broad grip area that straight tweezers offer for holding multiple lashes in place. Flat tweezers, on the other hand, provide a different type of grip and may not be as effective for isolating specific lashes due to their shape and design. Therefore, straight tweezers stand out as the optimal choice for the task of holding side lashes away during the application of eyelash extensions.
