Ridges on fingernails are known as onychorrhexis if they are vertical and Beau's lines if they are horizontal. While they are usually nothing to worry about, they can sometimes indicate an underlying medical issue. For instance, vertical ridges can be a sign of ageing, iron deficiency, or a more serious condition like Witkop syndrome, whereas horizontal ridges can be caused by malnutrition, nail trauma, or severe infections.

What You'll Learn
- Vertical lines are often a sign of ageing, whereas horizontal lines can indicate malnutrition
- Horizontal lines are called Beau's lines and can be a symptom of serious conditions
- Vertical lines can be caused by a slowing of cell turnover, which is common in older adults
- Horizontal lines can be caused by nail trauma, such as dropping something heavy on your toe
- Horizontal lines can also be caused by artificial nails or long-term gel manicures
Vertical lines are often a sign of ageing, whereas horizontal lines can indicate malnutrition
Vertical lines on the fingernails, also known as longitudinal striations or bands, are a common occurrence in older adults. This is due to a slowing of cell turnover, where new skin cells produced below the surface of the skin take longer to replace dead cells on the surface. While these lines are not usually a cause for concern, they can sometimes be accompanied by texture changes in the nails, which may indicate a medical condition such as trachyonychia (twenty-nail dystrophy). Additionally, certain medical disorders, such as anaemia, can contribute to vertical nail ridges, often accompanied by colour changes or dents in the nail.
On the other hand, horizontal lines on the fingernails, known as Beau's lines, can indicate more serious underlying health issues. Beau's lines are deep horizontal ridges that can appear on one or more fingernails or toenails. They are often a sign that an illness, injury, or skin condition has interrupted nail growth. While Beau's lines themselves are not harmful, they can be caused by a variety of factors, including physical trauma, chronic conditions, skin conditions, emotional stress, or nutritional deficiencies. For example, severe emotional stress, such as a divorce or job loss, can cause Beau's lines, and nutritional deficiencies, such as a lack of zinc or protein, can also be a contributing factor.
It is important to note that the appearance of Beau's lines may indicate an underlying condition that requires medical attention. Some of the associated conditions include diabetes, peripheral artery disease, hypothyroidism, and acute kidney disease. Therefore, if an individual notices the appearance of Beau's lines and is unsure of the cause, it is recommended to consult a healthcare provider to rule out any potential health concerns.
The treatment for Beau's lines focuses on addressing the underlying cause. Once the underlying condition is treated, nail growth should return to normal, and smooth nails will grow in place of the ridged ones. In the meantime, individuals can temporarily hide the ridges by applying a nail ridge filler and nail polish. However, it is important to exercise caution when using nail products, as some can weaken or damage the nails.
While vertical lines on the fingernails are often a natural sign of ageing, horizontal lines can indicate more serious health issues. Therefore, it is important to pay attention to any changes in the nails and consult a healthcare professional if there are concerns.

Horizontal lines are called Beau's lines and can be a symptom of serious conditions
Horizontal lines on the fingernails, known as Beau's lines, can indicate an underlying serious condition. These lines are deep horizontal ridges or dents that run across one or more fingernails or toenails. Beau's lines are often a sign that an illness, injury, or skin condition has interrupted nail growth. While the lines themselves are not harmful, they may indicate an underlying issue that requires medical attention.
There are various causes of Beau's lines, including physical trauma or damage to the nail matrix, such as dropping something heavy on the finger or exposure to extreme cold. Chronic conditions that interfere with blood flow to the nail matrix, such as hypothyroidism, peripheral artery disease, or Raynaud's phenomenon, can also lead to the formation of Beau's lines. Additionally, severe emotional stress, such as divorce, job loss, or the death of a loved one, can be a factor.
Certain medical conditions are associated with Beau's lines. For example, people with diabetes, peripheral artery disease, or acute kidney disease may experience these horizontal ridges. Additionally, vitamin and mineral deficiencies, such as a lack of zinc or protein, can contribute to the development of Beau's lines. In some cases, they may also appear after chemotherapy or as a result of certain infections, such as mumps or syphilis.
It is important to consult a healthcare professional if Beau's lines appear without an obvious cause. While there is no specific treatment for Beau's lines, addressing the underlying cause can help prevent their recurrence. Treating the underlying condition or managing factors like blood sugar levels in the case of diabetes, can promote the growth of smooth nails. In some cases, the appearance of Beau's lines may be improved by applying creams or moisturisers to the affected area, particularly for those with skin conditions like eczema or psoriasis.

Vertical lines can be caused by a slowing of cell turnover, which is common in older adults
Fingernail ridges are often early indicators of other health issues. Vertical ridges, also known as longitudinal striations or bands, are furrows that run from the tip of the fingernail to the cuticle. They are usually harmless and are a common part of the ageing process, particularly in older adults, due to a slowing of cell turnover. This is when new skin cells produced below the skin's surface rise up to replace dead skin cells that are shed from the surface.
While vertical lines on the fingernails are usually nothing to worry about, they can sometimes indicate a health problem, such as vitamin or mineral deficiencies. For example, a lack of vitamins A, B, C, D, E, zinc, selenium, iron, folic acid, or protein can result in fingernail ridges. If you experience other symptoms like texture changes in your nails, it may be caused by a medical condition. In trachyonychia (twenty-nail dystrophy), the ridges may be deeper and more pronounced.
If you are concerned about the appearance of vertical lines on your fingernails, it is recommended to consult a dermatologist, especially if the lines are causing you pain or are affecting your nail's appearance in a way that makes you unhappy. A dermatologist will be able to assess the ridges and determine if they are caused by normal ageing or if there is an underlying health issue that needs to be addressed.
While vertical lines on the fingernails are typically benign, it is always a good idea to pay attention to any changes in your body, including your fingernails, as they can sometimes indicate underlying health issues.

Horizontal lines can be caused by nail trauma, such as dropping something heavy on your toe
Horizontal lines on your fingernails, also known as Beau's lines, can be caused by nail trauma, such as dropping something heavy on your finger or toe. Beau's lines are horizontal ridges or dents that appear in one or more fingernails or toenails. They indicate that an illness, injury, or skin condition has interrupted nail growth. While Beau's lines themselves are not harmful, they may signal an underlying condition that requires medical attention.
Nail trauma, such as physical injury to the nail, can cause Beau's lines. For example, dropping a heavy object on your finger or toe can result in bruising under the nail and temporary changes in its shape. This type of trauma can lead to the formation of horizontal lines across the nail. It's important to note that nail injuries typically do not require treatment unless the damage is extensive. However, if you experience nail trauma or notice changes in your nails, it is advisable to monitor your symptoms and seek medical advice if necessary.
In addition to physical trauma, Beau's lines can also be caused by other factors. Chronic conditions that interfere with blood flow to the nail matrix, such as hypothyroidism, peripheral artery disease, and Raynaud's phenomenon, can lead to the development of horizontal lines. Skin conditions, such as eczema or psoriasis, and emotional stress are also potential factors. Additionally, nutritional deficiencies, particularly in zinc and protein intake, have been linked to the formation of Beau's lines.
Treating the underlying cause of Beau's lines is crucial to promoting the regrowth of smooth nails. While there is no specific treatment for Beau's lines themselves, addressing the underlying condition can prevent their recurrence. Proper nutrition, including adequate zinc and protein intake, is essential for nail health. In cases of chronic conditions or skin disorders, consulting a healthcare professional is recommended to determine the appropriate treatment approach.
It is important to be cautious when using nail products, as some can weaken or damage nails. If you notice any changes in your nails, it is always a good idea to consult a dermatologist or healthcare provider to rule out any potential health concerns. They can provide guidance on treating any underlying conditions and advise on nail care practices to support the growth of healthy, smooth nails.

Horizontal lines can also be caused by artificial nails or long-term gel manicures
Horizontal lines on the fingernails, also known as Beau's lines, can be caused by various factors, including artificial nails and long-term gel manicures. Beau's lines are characterized by deep, horizontal ridges or dents in one or more fingernails or toenails. While they are not a disease in themselves, they indicate that an underlying condition or factor has interrupted nail growth temporarily.
Artificial nails and long-term gel manicures can contribute to the development of Beau's lines. The application and removal processes of artificial nails and gel manicures can exert trauma or damage to the nail matrix, leading to the formation of these horizontal ridges. It is crucial to exercise caution when using such nail enhancements to minimize potential harm to the nails.
Additionally, chronic conditions that interfere with blood flow to the nail matrix can be a factor. Conditions such as hypothyroidism, peripheral artery disease (PAD), and Raynaud's phenomenon can impact blood circulation, affecting nail growth and resulting in Beau's lines. It is important to manage these underlying conditions effectively to promote healthy nail growth.
Emotional stress is another factor that can contribute to the appearance of Beau's lines. Significant life events, such as divorce, the death of a loved one, or job loss, can induce severe emotional stress, which in turn can manifest as horizontal ridges in the fingernails. Addressing and managing stress through appropriate self-care and support is essential to alleviate its impact on nail health.
While Beau's lines themselves are not harmful, they serve as a visual indicator of potential underlying issues. If you notice these horizontal lines, it is recommended to consult a healthcare professional to identify and address any associated conditions or lifestyle factors that may be causing the interruption in nail growth. Treating the underlying cause is key to restoring smooth and healthy nail growth.
