What is the function of a nail tip?

A nail tip primarily serves the function of extending the length of a natural nail. Nail tips are usually made of plastic and are adhered to the natural nail to provide an additional surface that can be shaped and styled. This makes it possible for clients to achieve longer nails than what their natural growth allows.

Enhancing color, while a possibility when using tips in conjunction with polish or other enhancements, is not the primary function of the nail tip itself. Strengthening the natural nail can occur with certain products or techniques, but it is not a function of the nail tip alone. Massaging the cuticles, while important for nail care, is unrelated to the function of nail tips.

Thus, the correct answer emphasizes the main purpose of nail tips, which is to add length and allow for more versatile nail designs.
