• A. Cosmetologists should wash their hands with warm water and liquid soap
• B. Cosmetologists should wear gloves
• C. Cosmetologists should sanitize tools
• D. Cosmetologists should use sanitizer

Answer: (A)

Washing hands with warm water and liquid soap before a service is the primary way to remove dirt, oils, and microbes from the skin. The combination of soap and the mechanical rubbing action lifts contaminants off the hands, and rinsing washes them away. Warm water helps loosen oils, and liquid soap tends to rinse off more cleanly and reduce transfer compared to other soap forms. Drying hands afterward is also important to prevent remaining moisture from harboring microbes.

Gloves are important in certain procedures or when you have a skin issue, but they aren’t a substitute for handwashing; hands should be cleaned before putting on gloves and after removing them. Sanitizers can be useful when soap and water aren’t available or as a supplementary step after washing, but they don’t remove visible dirt and aren’t a complete substitute for washing before a service.

So this statement aligns with standard hand-hygiene practice and is the best choice.
