Cosmetology · Nail and Skin Service Safety

The general rule for any tool that touches a client's skin, nails, or hair is:

Correct answer

Clean and disinfect reusable tools, and discard single-use ones, before reuse

  1. A Never clean anything
  2. B Only clean metal tools once a month
  3. C Use it on everyone
  4. D Clean and disinfect reusable tools, and discard single-use ones, before reuse

Why this is the answer

The general rule across all cosmetology services is that any tool contacting a client's skin, nails, or hair must be cleaned and disinfected (if nonporous and reusable) or discarded (if single-use/porous) before it is used again. This single principle underlies infection control for hair, skin, and nail services alike. The exam repeatedly tests whether candidates apply this rule consistently to every implement and service. Internalizing it as a universal habit is one of the most important safety takeaways of the licensing exam.
