Why do nails become more prone to developing horizontal ridges with age?

As individuals age, their nails may become more prone to developing horizontal ridges, also known as Beau’s lines. These ridges are characterized by indentations or depressions that run horizontally across the nail plate.

Possible Causes

There are several factors that can contribute to the development of horizontal ridges in nails with age:

Nail matrix changes: The nail matrix, which is responsible for producing new nail cells, may undergo changes as a person ages. These changes can affect the quality and texture of the nail plate, leading to the formation of ridges.

Reduced blood flow: With age, blood circulation to the extremities, including the nails, may decrease. This reduced blood flow can impact the delivery of essential nutrients and oxygen to the nail matrix, affecting nail growth and leading to the formation of ridges.

Dehydration: Older individuals may experience reduced hydration levels in their bodies, including the nails. Dehydration can cause the nails to become brittle and more prone to developing ridges.

Medical conditions: Certain medical conditions, such as psoriasis, eczema, and thyroid disorders, can affect nail health and contribute to the development of ridges.

Injury or trauma: Over time, the nails may have experienced repeated injury or trauma, which can lead to the formation of ridges. This can be due to factors such as manual labor, sports activities, or even habitual nail biting.

Treatment and Prevention

While horizontal ridges in nails are often a natural part of the aging process, there are steps individuals can take to minimize their occurrence and improve overall nail health:

• Maintain proper nail care: Regularly trimming and filing the nails can help prevent the development of ridges. It is important to use gentle techniques and avoid excessive force or pressure.
• Moisturize the nails: Applying moisturizers or cuticle oils to the nails can help keep them hydrated and prevent brittleness.
• Eat a balanced diet: Consuming a diet rich in essential nutrients, such as vitamins A, C, and E, as well as biotin and iron, can promote healthy nail growth.
• Protect the nails: Wearing gloves during activities that may cause nail trauma, such as gardening or household chores, can help prevent damage and ridges.
• Consult a healthcare professional: If the ridges are severe, persistent, or accompanied by other concerning symptoms, it is advisable to seek medical advice for proper diagnosis and treatment.
