What is the normal water content range of nails?

The normal water content range of nails is typically between 15-25%. Nails, like many biological tissues, contain a significant amount of moisture to maintain their flexibility and resilience. This hydration is crucial as it helps prevent brittleness, reduces the chances of cracking or splitting, and allows the nails to maintain structural integrity during everyday activities.

Understanding this range is important for nail technicians, as it informs product selection and the techniques used in nail care. For instance, nails that are too dry may benefit from moisturizing treatments, while those with higher moisture content might not require the same level of hydration. This knowledge also aids in identifying potential nail disorders, as deviations from the normal range can indicate underlying health issues or damage.
