What does "porous" refer to concerning items in a salon?

"Porous" refers to materials that have tiny holes or spaces, which allow liquids and gases to pass through or be absorbed. In the context of a salon, when items are described as porous, it means that they can absorb moisture, chemicals, and other substances. This property makes porous items less hygienic than non-porous items, as they cannot be adequately sanitized or disinfected between uses.

For example, certain fabrics, sponges, or natural materials can retain hair products, skin cells, or bacteria, potentially leading to contamination. Understanding the nature of porous items is crucial for maintaining sanitation standards in a salon environment, where the health and safety of clients are a priority. Thus, recognizing that porous items should typically be disposable or designated for single use reinforces the practice of hygiene in salon settings.
