What term describes the condition where nails turn a variety of colors?

The term "discolored nails" accurately describes the condition where nails exhibit various colors. This terminology encompasses a range of color changes, which can be indicative of numerous underlying health issues or conditions affecting the nails. These colors may vary from yellow, green, blue, or purple and can result from factors such as infections, nutritional deficiencies, or systemic diseases.

Understanding this terminology is crucial for professionals in cosmetology as it aids in recognizing potential health concerns that may need to be addressed before proceeding with services. It emphasizes the importance of being vigilant about changes in nail color as they can serve as visible signs of health beyond mere cosmetic appearance. In contrast, the other terms do not accurately capture the general condition of nails changing in color; instead, they refer to specific conditions or abnormalities in nail structure or appearance. For example, leukonychia refers specifically to white spots on the nails, koilonychia describes spoon-shaped nails, and onychauxis pertains to thickened nails.
