Which of the following is NOT a characteristic of a healthy nail?

A healthy nail is typically characterized by a smooth surface, consistent color, and being strong and flexible. Nails should be free of any defects or irregularities. The presence of pitting is an abnormal condition characterized by small indentations on the nail surface, which can indicate underlying health issues or conditions such as psoriasis or other skin disorders. This makes pitting a key sign of an unhealthy nail rather than a healthy one. The other qualities noted, such as a smooth surface and consistent coloration, reflect good nail health and indicate that the nail is growing properly and is not compromised by damage or disease. Strong and flexible nails are also vital as they can withstand the everyday rigors without splitting or breaking, signifying good overall health and proper care.
