What is the purpose of applying a nail dehydrator?

To strengthen
To remove moisture
To add shine
To extend length

The correct answer is: To remove moisture

A nail dehydrator is used to remove moisture from the nail bed before applying nail polish or artificial nails. This creates a clean and dry surface for the polish or nails to adhere to, leading to a longer lasting manicure or set of artificial nails. "To strengthen" (A) and "to extend length" (D) may seem like possible purposes for a nail dehydrator, but they are not its primary functions. "To add shine" (C) is also incorrect as a nail dehydrator does not necessarily add shine to the nails. It simply prepares them for the application of other products. Therefore, the purpose of a nail dehydrator is specifically to remove moisture, making option B the correct answer.
