Which factor is crucial for determining proper infection control in the lash extension process?

The cleanliness of tools is fundamental for maintaining proper infection control during the lash extension process. When applying eyelash extensions, various tools such as tweezers, scissors, and trays come into direct contact with both the client's natural lashes and the skin around the eyes. If these tools are not properly sanitized, they can harbor bacteria, viruses, or other pathogens that could lead to infections.

Ensuring that all tools are cleaned, disinfected, and sterilized as appropriate minimizes the risk of cross-contamination between clients and helps protect both the technician and the client from potential health issues. The application environment should also be clean to maintain a high standard of hygiene, which further supports effective infection control.

While client consultation, the type of adhesive used, and lash length selection are important aspects of the lash extension process, they do not directly impact infection control in the same way that the cleanliness of tools does. Therefore, maintaining high standards of cleanliness for all tools and equipment is crucial to ensure a safe and healthy experience for clients receiving eyelash extensions.
