What must be done to the areas of the client's body prior to a temporary hair removal service?

Prior to a temporary hair removal service, it is essential that the areas of the client's body are clean. This is crucial for several reasons. First, cleaning the skin helps to remove any dirt, oils, and bacteria that could interfere with the hair removal process or introduce contaminants that could lead to skin irritation or infection. A clean surface ensures that any products used, such as wax or depilatory creams, adhere properly and perform effectively. Additionally, cleanliness contributes to the overall comfort of the client and promotes better results, as any residual substances on the skin can affect the hair removal process.

While other options may seem relevant, they do not address the fundamental need for cleanliness before a hair removal procedure.
