Step-by-step explanation:
An esthetician would use hard wax mainly for sensitive areas like the eyebrows, upper lip, and bikini area, due to its ability to adhere solely to hair, reducing pain and irritation. As an esthetician, you would most likely use hard wax to wax a client's more sensitive areas, such as the eyebrows, upper lip, and bikini area. Hard wax adheres only to the hair and not the skin, which can reduce pain and irritation in these sensitive spots. Unlike soft wax, hard wax is applied in a thick layer and removed without the use of strips, making it more suitable for small, precise areas where more delicate work is needed.
