What procedure involves using depilatories or waxes?

The procedure that involves using depilatories or waxes is indeed related to hair removal. Depilatories are chemical products that break down the structure of hair, allowing it to be easily wiped or washed away from the skin's surface. Waxing, on the other hand, is a physical method wherein a warm wax is applied to the skin and then removed, taking the hairs along with it. Both methods aim to achieve smooth, hair-free skin and are commonly used in salons.

In contrast, hair drying involves the use of heat or airflow to remove moisture from hair, which does not involve removing hair itself. Skin exfoliation is a procedure that focuses on removing dead skin cells to improve skin texture and appearance, rather than addressing unwanted hair. Scalp cleansing refers to the process of cleaning the scalp, usually in relation to hair care, but it does not pertain to hair removal. Therefore, hair removal is the correct association with the use of depilatories and waxes.
