Which hygiene practice is essential before performing any procedure on a client?

• A. Ventilation check
• B. Wearing gloves
• C. Sanitize tools only after procedures
• D. Handwashing or sanitizing hands prior to starting work

Answer: (D)

Hand hygiene before starting any client contact is the foundation of infection prevention in barbering. Thoroughly washing with soap and water or using an approved hand sanitizer removes or kills the microorganisms you could transfer to the client, tools, or surfaces. This step is essential even if you plan to wear gloves, because gloves don’t eliminate the risk of contamination from hands to client if hands aren’t clean to begin with, and gloves can have micro-tears or become contaminated during removal. Tools should be cleaned and disinfected between clients as part of proper hygiene, not only after a procedure. Ventilation checks address the room environment, not the direct hygiene practice needed before touching a client.
