What are the signs of a bacterial infection in the salon?

The signs of a bacterial infection in the salon include redness, swelling, and pus in affected areas. These indicators are commonly associated with infections and result from the body’s inflammatory response to pathogens. When bacteria enter the skin through cuts or abrasions, the immune system responds by increasing blood flow to the area, leading to redness and swelling. The presence of pus, which is a collection of dead white blood cells, bacteria, and tissue debris, further indicates that an infection is present.

In contrast, the other options reflect different skin or hair conditions rather than infections. Dry skin and flaking could indicate a condition like eczema or psoriasis, while excessive oiliness pertains to seborrhea or other skin issues that do not inherently signify infection. Changes in hair color are typically linked to chemical processes or environmental factors and do not suggest a bacterial infection. Understanding these distinctions is crucial for maintaining a safe and hygienic salon environment.
