What is the name of the nail product that gives color and shine?

The nail product that gives nails color and shine is nail polish. Also called nail varnish or nail enamel, it is a lacquer applied to fingernails or toenails for decoration and protection.

Modern nail polish usually contains a film-forming polymer, commonly nitrocellulose, dissolved in a volatile solvent. Pigments provide color, while other ingredients influence gloss, flexibility, drying time, and durability. Gel polish uses acrylate-based materials and is hardened with ultraviolet or LED light, making it different from ordinary air-drying polish.

Nail polish has a long history. Nail-coloring traditions in China are often dated to around 3000 BCE, and ancient Egyptians used henna to tint nails. Base coat is applied before colored polish to improve adhesion and help prevent staining; top coat is applied afterward to add protection and shine. Neither is the general name for the colored product itself. Regular polish may last several days, while properly applied gel polish can last around two weeks.
