Name a method of hair removal that involves the use of a heated wax.

Waxing is the method of hair removal that involves the use of heated wax. During the waxing process, warm wax is applied to the skin in the direction of hair growth. When it cools slightly, a strip of cloth or paper is placed over the wax and is quickly pulled away against the direction of hair growth, effectively removing the hair from the root. This technique not only offers longer-lasting results compared to shaving but can also result in finer regrowth over time.

The other methods mentioned serve different purposes or employ different techniques. Shaving cuts the hair at the skin's surface and does not remove it from the root, which means regrowth occurs more rapidly. Threading, predominantly used for facial hair removal, involves twisting a thread to pull hairs from their follicles, while epilating refers to the use of an epilator device that mechanically removes hair from the root but does not involve the application of wax. Thus, while they all relate to hair removal, waxing specifically utilizes heated wax as a key component of its method.
