What might cause nail ridges in natural nails?

Nail ridges in natural nails can be attributed to factors such as aging, nutritional deficiencies, or trauma. As individuals age, the natural growth and health of their nails can be affected, leading to changes in texture and strength, which may manifest as ridges. Nutritional deficiencies, such as a lack of essential vitamins and minerals, can also impact nail health, causing them to develop into ridged patterns. Additionally, trauma to the nails, whether from physical damage or harsh substances, can disrupt normal nail growth and lead to the appearance of ridges. This combination of biological and environmental factors plays a significant role in the condition of natural nails and their overall appearance.
