Nail polish is a cosmetic product applied to the nails to enhance their appearance. It comes in various colors and finishes, such as glossy, matte, or glittery. Nail polish is typically made from a mixture of solvents, resins, and pigments, which help it adhere to the nail surface and provide a vibrant color. To apply nail polish, one usually starts with a base coat to protect the nails, followed by one or more layers of colored polish, and finishes with a top coat for shine and durability. Proper application can help prevent chipping and extend the life of the manicure, making it a popular choice for personal grooming and self-expression.
