Waxing is an example of a non-chemical method for hair removal because it utilizes physical means to remove hair from the root. This process involves applying a warm (or cold) wax to the skin, placing a cloth strip over it, and then quickly pulling the strip away, which removes the hair along with the wax. This technique relies on the adherence of the wax to the hair and the subsequent removal through physical force, rather than a chemical reaction, making it a non-chemical approach.

In contrast, the other options involve chemical or technological methods for hair removal. For instance, laser hair removal uses concentrated light to target and damage hair follicles, while depilatory creams contain chemicals that dissolve hair. Electrolysis involves the use of electric currents to permanently destroy hair growth, which is also a technological method. Thus, waxing stands out as the only option that strictly employs non-chemical techniques for hair removal.
