Which type of wax is removed when it is set?

Hard wax is the correct choice because it is specifically designed to harden as it cools, allowing it to be removed without the need for a strip. This type of wax adheres to the hair rather than the skin, making it less painful upon removal and ideal for sensitive areas or coarse hair. Hard wax is applied warm and, once it has cooled and set, is pulled away by grasping the hardened wax itself, facilitating effective hair removal.

The other types of wax mentioned either do not harden or require a strip for removal. Soft wax and strip wax typically remain pliable, necessitating a cloth or paper strip to aid in their removal. Cold wax, on the other hand, is used at room temperature and also requires a strip. Understanding the properties of each wax is essential for determining their best uses in esthetic practices.
