Possible causes of stripes & lines on natural nails

Nail ridges, ridges or furrows are longitudinal lines or grooves that run along the nail plate. These lines can vary in depth and are caused by various factors. Understanding why they occur, what symptoms they cause and how they can be treated is crucial for proper nail care and to determine whether and which artificial nail products can improve the appearance of the nail.

Symptoms of nail grooves, ridges, or furrows

The main symptom is visible longitudinal lines or grooves on the nail surface. These can be subtle or more prominent, especially on longer nails. In some cases, small "pearl-shaped" defects may appear on the nail plate, which may indicate a more noticeable change. These nails are often hard and, as long as they do not have open cracks, can be improved with artificial nail products.

For people with these nail problems, permanent artificial nail products that require refilling, such as rubber base, acrylic or builder gel, are recommended. Soak-off products should be avoided as removing these can cause further damage to the already ridged nails, which often becomes visible only upon the next product removal.

Possible causes of nail ridges or nail stripes

  • Aging – With age, nail growth changes and can develop ridges, stripes, or furrows.

  • Trauma or injury – Damage to the nail bed can result in lines or grooves as the nail grows out.

  • Nutritional deficiencies – Lack of essential vitamins and minerals can affect nail health and lead to ridges.

  • Underlying health problems – Certain medical conditions can cause ridges, and their appearance can change over time depending on the health condition.

Who is affected by nail ridges?

Nail ridges can affect people of all ages but are more common in adults. The condition is not linked to any specific gender or ethnic group.
