What is included in the practice of eyelash technicians?

The practice of eyelash technicians primarily involves the application, removal, and trimming of eyelash extensions or fibers to enhance the length and volume of natural lashes. This process is essential to ensure that the extensions are applied correctly and safely, providing the desired aesthetic results for clients while maintaining the health of their natural lashes.

Application and removal are critical components of the technician's role, as they must be trained to handle adhesives and ensure that the extensions are securely attached and can be removed without damaging the client's natural eyelashes. Additionally, proper trimming is necessary to create a natural look and to customize the extensions to fit the individual client's eye shape and personal style.

The other options do not accurately reflect the specific scope of practice for eyelash technicians. The application and removal of color agents are more in line with hair coloring services rather than eyelash work. Providing facial treatments involves a different set of skills and licenses. Finally, the use of permanent wave solutions pertains to hair treatments and does not apply to eyelashes. Thus, the correct choice encapsulates the core activities that define the role of an eyelash technician.
