Using separate tools for each client is the best practice for preventing cross-contamination. This approach significantly reduces the risk of spreading bacteria, viruses, or other pathogens between clients, as each individual receives service with tools that have not been in contact with another client's skin or hair. By maintaining a dedicated set of tools for each client or using disposable items, cosmetologists create a safer environment and uphold hygiene standards critical in beauty settings.

Other methods, such as cleaning tools after use or reusing them, may not adequately prevent cross-contamination, especially if the cleaning process is not thorough or timely. Sharing products among clients can also lead to contamination, as multiple clients using the same product can easily transfer microorganisms. Regular sanitation practices are essential, but they do not substitute for the primary measure of using separate tools, particularly in a professional cosmetic practice.
