When must cosmetologists wash their hands or use hand sanitizer?

• A. After completing the service
• B. During the service
• C. Prior to servicing each client
• D. Only when hands are visibly dirty

Answer: (C)

The main concept is hand hygiene before any client contact to prevent cross-contamination. Washing hands or using hand sanitizer before servicing each client establishes a clean starting point, reducing the risk of transferring germs, chemicals, or other contaminants from your hands to the client’s skin, nails, or the tools you’ll use. If you wait until after the service, contamination could occur during the procedure, and some pathogens aren’t visible to the eye, so relying on post-service cleaning isn’t enough. Washing during the service is impractical and interrupts the workflow, and washing only when hands are visibly dirty ignores the many germs that aren’t visible. So, the best practice is to sanitize or wash hands before you begin with every client, preserving a hygienic baseline for the entire service. Between clients, re-clean as needed if you’ve touched something contaminated, but the crucial moment is the pre-client hand hygiene.
