Final answer:
The statement is false; hard wax is actually thicker than soft wax, which is important for its ability to grip and remove hair effectively, especially from sensitive areas with thicker skin.
Step-by-step explanation:
The statement that hard wax is thinner than soft wax is false. When comparing types of waxes used for hair removal, it is commonly noted that hard wax is typically thicker because it needs to be applied in a thick layer to be able to grip and remove the hair without the use of cloth strips. On the other hand, soft wax is thinner and is usually spread thinly over the skin and then removed with the aid of fabric or paper strips. This difference is particularly important for waxing sensitive areas such as the fingertips and lips, where the skin is already thicker (4 to 5 mm for glabrous skin) compared to hairy skin (2 to 3 mm).
