What must a cosmetologist ensure when using shared tools?

When using shared tools, a cosmetologist must ensure that they are cleaned and disinfected. This is crucial for maintaining hygiene and preventing the spread of infections and diseases between clients. Proper cleaning and disinfection of tools such as scissors, combs, and brushes ensure that any pathogens, hair, skin cells, or product residues left from one client are effectively removed before being used on another. This practice aligns with public health guidelines and is fundamental to maintaining a safe and sanitary environment in a cosmetology setting. Prioritizing cleanliness helps promote trust and safety for both clients and professionals.
