What tool is typically used for isolation in eyelash extensions?

The correct answer is the curved tweezers, which are specifically designed for precise isolation of individual natural lashes during the application process of eyelash extensions. Their curved design allows for better access to the lashes, enabling the lash technician to isolate one lash from the others efficiently. This isolation is crucial for proper application, as it ensures that the extension is bonded only to a single natural lash and prevents any potential clumping or sticking to adjacent lashes.

The use of curved tweezers not only enhances precision but also improves the overall speed and quality of the application. Their ergonomic design can reduce strain on the technician’s hand and wrist during lengthy appointments, contributing to better technique and results.

In contrast, scissors are not used for isolation as they are meant for cutting, whereas a brush is used for grooming or cleaning the lashes, and a ruler does not fulfill a role related to lash isolation at all. Each of these tools has its specific function in the lash extension process, highlighting the importance of selecting the correct tool for each task to achieve optimal results.
