What must a salon have to ensure public health and welfare?

To ensure public health and welfare, a salon must have adequate workspace for cleanliness and disinfection. This is crucial because a clean and properly maintained environment reduces the risk of spreading infections and maintains a safe atmosphere for both clients and staff.

Proper workspace allows professionals to carry out their services without contamination risks, ensures that tools and equipment can be effectively sanitized, and provides sufficient room for organizing products and materials in a way that supports hygiene practices. A focus on cleanliness and disinfection is foundational in the cosmetology industry to comply with health regulations and prevent any health-related incidents.

The other options do not directly contribute to public health and safety in the same way. A large display area for products, while visually appealing and important for sales, doesn't address sanitation requirements. A reception desk without barriers might enhance client interaction but does not influence cleanliness. A restroom facility is necessary for convenience and comfort but is not a comprehensive solution for overall public health in the salon environment.
