What characteristic differentiates hard wax from soft wax?

Hard wax is specifically designed to set quickly and has a unique lip or edge that allows for easy removal without the need for a cloth strip. This characteristic makes it particularly effective for sensitive areas, such as the face and bikini line, where precision is important. By solidifying upon cooling, hard wax adheres to the hair rather than the skin, which can minimize discomfort during the hair removal process.

Other types of wax, such as soft wax, require strips for removal and tend to adhere to both the hair and the skin, which can lead to a different experience during the waxing process. The quick setting and ease of removal of hard wax cater to specific waxing techniques, making them suitable for a variety of clients and hair types. Understanding this feature is vital for estheticians as it impacts the choice of products based on the clientele's needs and the areas being treated.
