Which of the following is an important hygiene practice in eyelash extension application?

Using clean tools for each client is a fundamental hygiene practice in eyelash extension application because it helps prevent the spread of bacteria, viruses, and other pathogens. Clean tools ensure that any materials that come into contact with a client's skin or eyelashes do not transfer harmful organisms. This practice is essential for maintaining a safe and sanitary working environment, which protects both the technician and the client from potential infections or allergic reactions.

Additionally, clean tools help to ensure the integrity of the eyelash extensions application, as dirty tools can affect the quality of the bond between the natural lash and the extension. Proper sanitation protocols promote the health and safety of all clients, creating a professional atmosphere that encourages customer trust and satisfaction.
