What is the water content range of a healthy nail?

A healthy nail typically contains a water content range of approximately 15 to 25 percent. This moisture level is crucial for maintaining flexibility and strength, ensuring that the nails are resilient against breaking or chipping. The presence of water in the nail helps to maintain its integrity, allowing it to respond well to external stresses without becoming overly brittle or soft.

In contrast, water content levels outside this range can lead to various issues. For example, a lower water content may result in dry, brittle nails that are more prone to breakage, while excessive moisture might contribute to nail fragility and make them more susceptible to fungal infections. Therefore, understanding the optimal moisture content is key for both nail health and effective nail care practices in cosmetology.
