Horizontal ridges in your nails, also known as Beau's lines, can be a sign of a health condition or a previous injury to your nail. They are usually deeper than vertical ridges and can be caused by malnutrition, nail injury, thyroid disease, peripheral vascular disease, severe illness, or nutritional deficiencies.

What You'll Learn
Horizontal nail ridges are called Beau's lines
Vertical nail ridges, on the other hand, are often a sign of ageing. They are sometimes called longitudinal ridges or striations and are common in older adults. Vertical ridges can also be a symptom of onychorrhexis, a condition that causes the nails to split and can be caused by a fungal infection.
While Beau's lines are usually associated with more severe health issues, it's important to note that ridges in nails can sometimes be harmless. If you are concerned about the appearance of ridges in your nails, it is best to consult a dermatologist or healthcare professional. They can help determine the underlying cause and provide appropriate treatment or advice.

Beau's lines are linked to serious health issues
Horizontal ridges in your nails are called Beau's lines. While vertical ridges are usually harmless and caused by the ageing process, Beau's lines are often linked to more serious health issues. Beau's lines are deeper than vertical ridges and can be caused by a number of factors, including severe infections, diabetes, nutritional deficiencies, hypothyroidism, chemotherapy, damage from using artificial or acrylic nails, injury to the nail, peripheral vascular disease, and severe illness with a high fever, such as COVID-19, measles or pneumonia.

Horizontal nail ridges can be caused by malnutrition
Nutrition plays a vital role in maintaining healthy nails. A well-balanced diet that includes essential nutrients is key to nail health. Deficiencies in certain vitamins and minerals can lead to changes in the appearance and structure of nails, including the formation of horizontal ridges.
The most common nutrient deficiencies associated with nail ridges are iron, vitamin B12, and zinc. Iron and vitamin B12 are essential for nail growth and strength. A lack of these nutrients can disrupt the normal growth pattern of the nails, resulting in horizontal ridges. Zinc is also crucial for nail health, as it plays a role in protein synthesis and tissue repair. A zinc deficiency can affect the integrity of the nail structure, making it more susceptible to damage and the development of ridges.
In addition to these key nutrients, other dietary deficiencies can contribute to nail ridges. For example, a lack of essential fatty acids, such as omega-3 and omega-6, can impact nail health. These fatty acids are necessary for maintaining the moisture and flexibility of nails, and their deficiency can lead to brittle nails with horizontal ridges.
It is important to address nutritional deficiencies to improve nail health. Ensuring a balanced diet rich in nutrients, including iron, vitamin B12, zinc, and essential fatty acids, is crucial. In some cases, supplements may be recommended to correct specific deficiencies. Consulting with a healthcare professional can help identify any nutritional gaps and determine the appropriate course of action to restore nail health and prevent further issues.

They can also be caused by injury
Horizontal ridges in your nails, also known as Beau's lines, can be caused by injury. This can be due to something interrupting your nail growth, such as slamming your finger in a door or dropping something on your foot. Beau's lines are often linked to more serious health issues, such as severe infections, diabetes, or nutritional deficiencies. They can also be caused by peripheral vascular disease (PAD) or a severe illness with a high fever, such as COVID-19, measles or pneumonia.
While vertical ridges are often a sign of ageing, horizontal ridges can point to issues like malnutrition, serious nail injury, or Beau’s lines. Ridges in your nails can be a sign of a health condition or a previous injury to your nail. In some cases, they’re harmless.

Thyroid disease can cause horizontal nail ridges
Horizontal nail ridges, also known as Beau's lines, can be caused by a variety of factors, including thyroid disease. While vertical nail ridges are often a sign of aging, horizontal ridges can indicate more serious health issues.
Thyroid disease, specifically hypothyroidism, can cause a range of nail abnormalities, including horizontal ridges. Individuals with hypothyroidism may experience thick, brittle nails with vertical or horizontal ridges. The nails may also crumble or break easily, appearing more rounded, and the fingertips may be puffy. These changes in nail appearance are due to the impact of thyroid disease on nail growth and the overall health of the nail bed.
Beau's lines are characterised by deep horizontal ridges or dents in the nails, which can occur when something interrupts normal nail growth. In the case of thyroid disease, the disruption in nail growth may be related to hormonal imbalances affecting nail matrix cells. Additionally, thyroid disease can impact circulation, which is crucial for nail health, further contributing to the development of Beau's lines.
While thyroid disease is one potential cause of horizontal nail ridges, other factors can also play a role. Beau's lines can be induced by severe illnesses with high fevers, such as COVID-19, measles, or pneumonia. Certain medications, such as chemotherapy, can also lead to the development of these ridges. Additionally, damage from using artificial nails, acrylic nails, or gel manicures for extended periods can contribute to the formation of horizontal nail ridges.
It is important to note that horizontal nail ridges may not always indicate a serious health issue. In some cases, they can be harmless or related to previous injuries to the nail. However, if you notice persistent or pronounced horizontal ridges, it is advisable to consult a healthcare professional. They can help determine if the ridges are indicative of an underlying condition, such as thyroid disease, and provide appropriate guidance and treatment.
