What is the key characteristic of a chemical depilatory?

1. Creates heat to remove hair

2. Dissolves hair at skin level

3. Requires a prescription

4. Can only be used on coarse hair

The correct answer is: Dissolves hair at skin level

The key characteristic of a chemical depilatory is that it dissolves hair at the skin level. Chemical depilatories contain active ingredients, such as calcium thioglycolate or potassium thioglycolate, that break down the protein structure of hair, allowing it to be easily wiped away from the skin's surface. This process is effective because it targets the hair just below the surface, making it a convenient option for hair removal without the need for physical methods like shaving or waxing. In contrast, the other options suggest different methods or requirements that do not apply to chemical depilatories. For example, the generation of heat to remove hair would typically describe methods like laser hair removal or waxing. The necessity of a prescription is more commonly associated with stronger medications or treatments rather than over-the-counter depilatories, which are generally accessible. Additionally, while chemical depilatories can be effective on various hair types, they are not limited to coarse hair; they can be used on fine or medium hair as well. This versatility makes them a popular choice for many individuals seeking hair removal solutions.
