The main difference between hard wax and soft wax lies in their application and removal process. Hard wax, as the name suggests, hardens upon cooling and can be removed without the use of a strip. This characteristic allows it to shrink around the hair as it cools, making it less painful during removal for certain treatment areas. In contrast, soft wax remains pliable, requiring a cloth or paper strip to remove it after application. This difference in form and technique gives each type of wax its unique advantages depending on the treatment area and hair type.

While hard wax is ideal for sensitive areas such as the bikini line and underarms due to its gentler removal process, soft wax is often preferred for large areas or finer hair because it can quickly cover more surface area and may adhere better to the skin. However, the necessity of a strip for soft wax fundamentally differentiates it from hard wax, which is why the correct answer emphasizes the characteristics associated with hard wax and soft wax in terms of their removal method.
