What function does a nail form serve?

A nail form is a tool used primarily in the process of creating nail extensions, especially with acrylic or gel applications. Its main function is to shape and support the extension of the nail as it is being built. When a nail technician applies a nail form, it acts as a mold that allows for the desired length and shape to be achieved, whether it be a square, oval, or another style. The form also provides the necessary support for the product (like acrylic or gel) as it hardens, ensuring a well-structured and aesthetically pleasing extension.

The other options pertain to different aspects of nail care and maintenance but do not relate to the specific purpose of a nail form. Disinfecting nail implements is crucial for hygiene and safety practices in a salon but is unrelated to the shaping of nails. Enhancing nail color is a function of nail polish and gels, not forms. Strengthening natural nails often involves the use of treatments or specialized products, rather than forms, which are intended for extensions and not directly for reinforcing natural nail integrity.
