Final answer:
Threading is considered more sanitary than waxing because it only uses thread, reduces the risk of removing skin layers, and the thread is disposed of after use, lowering cross-contamination risks.
Step-by-step explanation:
Threading is considered more sanitary than waxing because it involves contact with only the thread itself, reducing the risk of skin irritation and infection. Unlike waxing, threading does not remove a layer of skin which can leave the skin vulnerable to infection. Moreover, the thread used in threading can be disposed of after each use, minimizing the risk of cross-contamination between clients.
During waxing, the wax can sometimes be double-dipped into the wax pot, potentially leading to the spread of bacteria or infection, especially if the wax and the tools used are not properly sanitized between clients. Furthermore, people with sensitive skin may experience more redness and irritation from waxing compared to threading.
