Wax hair is the term used to describe _noun_ the process of removing unwanted body hair using hot or cold wax. This method is typically done in a salon or at home and involves spreading a thin layer of wax over the desired area, allowing it to cool and harden, and then quickly pulling it off in the opposite direction of hair growth.
Waxing is a popular hair removal technique because it is relatively simple and affordable, and the results can last for several weeks. It is also considered a more permanent hair removal method than shaving or tweezing, as it removes the hair from the root. The first known use of wax hair removal was in ancient Egypt, where beeswax was used for this purpose.
