What is the main purpose of a manicure?

The main purpose of a manicure is to improve the appearance and health of hands and nails. A manicure typically involves cleaning, shaping, and grooming the nails, along with caring for the surrounding skin. This process not only enhances the aesthetic appeal of the hands but also promotes the overall health of the nails and skin. Regular manicures can help prevent nail disorders and can contribute to better hygiene. This focus on health and appearance makes it clear why this option is the most accurate representation of the primary goals of a manicure.

The other options do involve aspects related to manicures, but they are not the primary purpose. Removing calluses is often associated with pedicures and foot care rather than manicures. While nail art is a popular addition to manicures, it is more of a decorative enhancement rather than the main objective. Promoting nail polish sales is more of a business strategy and not a fundamental purpose of performing a manicure. Therefore, the correct choice centers on the essential aim of promoting healthy and attractive nails and hands.
