Hard wax is a type of wax used primarily for hair removal. It is applied warm and hardens as it cools, allowing it to grip the hair without adhering strongly to the skin. This makes it effective for removing hair from sensitive areas, as it can minimize discomfort during the waxing process. Typically, hard wax is used in salons and at home for various body parts, including the face, bikini area, and underarms. It is often preferred for its ability to remove shorter hair and for providing a smoother finish compared to other waxing methods.
