Which term best describes the act of applying a false nail over a natural nail?

The term that best describes the act of applying a false nail over a natural nail is nail enhancement. This practice involves augmenting or improving the appearance of natural nails through various techniques, including the application of artificial nails, gel, acrylics, or other materials designed to enhance the aesthetic appeal and durability of the nails. Nail enhancements not only provide a cosmetic improvement but also allow for customization in shape, length, and design, catering to individual preferences.

In contrast, the other terms do not capture the specific action of applying false nails. Nail strengthening refers to methods aimed at improving the structural integrity of natural nails, while nail care encompasses broader maintenance practices, including cleaning and moisturizing nails and cuticles. Nail sculpture, while related to artificial nails, often refers to the art of molding materials to create specific shapes or designs, which may involve more detailed techniques than simply applying a false nail. Thus, nail enhancement is the most accurate term for this process.
