What can be a sign of dehydration or damage to nails?

Cracks and splits in the nails are indeed signs of dehydration or damage. When the nails lack moisture, they become brittle and prone to breaking. Healthy nails typically have some level of flexibility and resilience, allowing them to withstand daily activities. However, when they are dehydrated, the structural integrity is compromised, leading to visible cracks and splits. This condition can stem from environmental factors, such as frequent exposure to water or harsh chemicals, as well as nutritional deficiencies.

In contrast, excessive shine usually indicates well-kept nails, often enhanced by proper care or products. Bright coloration is associated with healthy nails; abnormal coloration might indicate other issues but not specifically dehydration. A perfect curvature in nails suggests good health and proper growth; it does not signal damage or dehydration. Thus, the presence of cracks and splits serves as an important indicator of nail health and the necessity for proper hydration and care.
