Which factor can lead to nail brittleness?

Lack of hydration is a major factor that can lead to nail brittleness. When nails do not receive adequate moisture, they lose their elasticity and can become dry and fragile. Hydration is essential for maintaining the natural moisture balance in the nails, which helps them remain strong and flexible. Without sufficient hydration, the structural integrity of the nail is compromised, making them more prone to breaking, chipping, and splitting.

While frequent filing, excessive buffing, and regular polishing can contribute to nail health issues, they do not have the same direct relationship with hydration levels in the nails. These practices, if done excessively, can cause thinning or damage, but ultimately, the primary cause of brittleness is related to a lack of moisture in the nails. Proper hydration through water intake, moisturization, and the use of nourishing oils is important for maintaining healthy, resilient nails.
