Which factor can significantly impact the longevity of a manicure?

The longevity of a manicure is heavily influenced by the type of nail polish used. Different nail polish formulations can affect how well the manicure adheres to the nail and how resistant it is to chipping, wear, and fading. High-quality polishes that offer strong formulas, such as those combined with gel-like finishes or those containing strengthening ingredients, typically provide better durability and a longer-lasting shine compared to lower-quality options.

While the length of the client's nails, frequency of salon visits, and weather conditions can also impact the overall experience and appearance of the manicure, they do not have as direct an effect on the actual performance and longevity of the polish itself. A high-quality polish can withstand wear better, regardless of nail length or environmental factors, making it a primary contributor to how long the manicure looks fresh and intact.
