Horizontal nail ridges, also known as Beau's lines, are often harmless and can be caused by manicures, artificial nails, or harsh nail products. However, they can also indicate more serious underlying health issues such as malnutrition, severe nail injury, peripheral vascular disease, or diabetes. If you notice persistent or worsening horizontal nail ridges, it is recommended to consult a healthcare professional or dermatologist to determine the underlying cause and receive appropriate treatment.

What You'll Learn
Horizontal nail ridges are called Beau's lines
There are various factors that can cause Beau's lines. Local trauma, such as slamming your finger in a door or dropping something heavy on your finger, can result in these horizontal ridges. Additionally, medical illnesses like endocarditis, pneumonia, or psoriasis can be a cause. Chronic conditions that interfere with blood flow to the nail matrix, such as peripheral artery disease (PAD) or Raynaud's phenomenon, can also lead to Beau's lines.
Nutritional deficiencies, especially a lack of zinc or protein, can also cause Beau's lines. Severe emotional stress, such as divorce, the death of a loved one, or job loss, can be a factor as well. Certain medical treatments, like chemotherapy, can interrupt nail growth and result in Beau's lines.
It is important to note that Beau's lines themselves are not harmful. However, they can indicate an underlying health issue or nutrient deficiency. If you notice Beau's lines and are unsure of the cause, it is recommended to consult a healthcare provider to rule out any potential health conditions. Treating the underlying cause is key to preventing Beau's lines from recurring as your nails grow out.

Beau's lines are caused by an injury or illness interrupting nail growth
Horizontal nail ridges, also known as Beau's lines, are often an indication of an injury or illness that has interrupted nail growth. Beau's lines are horizontal grooves or dents that appear on one or more nails and can vary in severity from barely visible to extremely deep. They are usually more noticeable on thumbnails.
Beau's lines are typically caused by a disruption in nail growth due to a severe illness or trauma. Certain illnesses, such as uncontrolled diabetes, kidney disease, or peripheral vascular disease, can cause these horizontal ridges to form. Additionally, physical injuries, such as slamming your finger in a door or dropping something heavy on your finger, can result in Beau's lines. In some cases, mental and emotional stress, severe enough to cause a disruption in nail growth, can also lead to the formation of Beau's lines.
The appearance of Beau's lines can provide clues about their underlying cause. For instance, thicker Beau's lines may indicate that the illness or trauma was prolonged. Multiple Beau's lines on a single nail may suggest that the trauma or illness occurred more than once. Additionally, the presence of nail thinning or discoloration alongside Beau's lines can be indicative of a more serious underlying illness.
While Beau's lines themselves are not harmful, they can be a sign of an underlying medical condition or nutrient deficiency. Therefore, it is important to consult a healthcare provider to determine the cause and receive appropriate treatment. Treating the underlying cause will allow new, smooth nails to grow, replacing the ridged nails over time.

They can be caused by zinc or iron deficiency
Horizontal nail ridges, also known as Beau's lines, can be caused by zinc or iron deficiency. Beau's lines are characterised by horizontal ridges or dents that develop across the nails, indicating an interruption in nail growth. While Beau's lines are not a disease in themselves, they can signify an underlying health issue or nutrient deficiency.
Zinc deficiency, in particular, can lead to the formation of Beau's lines and white spots on the nails. Ensuring proper nutrition, including adequate zinc intake, can help restore normal nail growth. In some cases, taking zinc supplements under the guidance of a healthcare provider may be recommended to address the deficiency.
Iron deficiency, on the other hand, is associated with vertical nail ridges and a condition called koilonychia, or spoon nails. Spoon nails exhibit a depression in the middle, giving the appearance that the centre of the nail has been scooped out. This type of nail ridge runs from the tip of the fingernail down to the cuticle. Addressing the iron deficiency through appropriate treatment or supplements can help improve nail health over time.
It is important to consult a healthcare provider to determine the underlying cause of horizontal nail ridges. While home care, such as moisturising and protecting the nails and cuticles, can improve the appearance of the nails, treating the underlying cause is crucial for promoting smoother nail growth. This may involve addressing nutritional deficiencies, managing chronic conditions, or recovering from illnesses or injuries that interrupted nail growth.

They can be caused by diabetes or thyroid disease
Horizontal nail ridges, also known as Beau's lines, can be indicative of underlying medical conditions such as diabetes or thyroid disease. Beau's lines are characterised by horizontal ridges or dents across one or more fingernails or toenails. While they are usually harmless, these nail ridges can be a sign of a previous or ongoing illness, injury, or nutritional deficiency.
Diabetes can cause horizontal nail ridges due to the impact of high blood sugar on nail growth. Elevated blood sugar levels can lead to indentations known as Beau's lines. Additionally, diabetes-related nerve damage, known as neuropathy, can inhibit nail growth, resulting in shorter nails or slower nail growth. Therefore, changes in nail growth rate or the appearance of horizontal ridges may warrant further investigation for potential diabetes.
Thyroid disease, a condition affecting the butterfly-shaped gland in the neck that regulates vital functions through hormone production, can also cause horizontal nail ridges. Thyroid disorders can lead to skin, hair, and nail changes, including thickened, dry, and brittle nails with visible ridges. These nail changes may be an early indicator of thyroid dysfunction, emphasising the importance of early detection and treatment to prevent complications such as irregular heartbeat.
It is important to note that horizontal nail ridges can have various causes, including local trauma, medical illnesses, and nutritional deficiencies. Therefore, if you notice persistent horizontal nail ridges or other nail abnormalities, it is advisable to consult a healthcare professional for proper diagnosis and treatment.

They can be treated by addressing the underlying cause
Horizontal nail ridges, also known as Beau's lines, can be caused by various factors, including local trauma, medical illness, nutritional deficiencies, and emotional stress. While Beau's lines are not harmful themselves, they can indicate an underlying health issue. Therefore, it is important to address the root cause to treat and prevent these ridges effectively.
If you notice horizontal nail ridges, it is recommended to consult a healthcare provider to determine the underlying cause. They may suggest specific treatments or lifestyle changes to address the issue. For example, if the ridges are caused by a skin condition like eczema, a healthcare provider may recommend moisturizers or topical ointments to alleviate symptoms and improve nail appearance. Similarly, if vitamin or mineral deficiencies are the cause, dietary changes or supplements may be advised to boost nutrient levels and promote healthier nails.
In some cases, horizontal nail ridges may be related to more serious conditions, such as acute kidney disease, endocarditis, or subungual melanoma. Therefore, it is crucial to seek medical advice and address any underlying health issues. Once the underlying cause is treated, Beau's lines will gradually grow out, usually taking about six months for complete nail regeneration.
While waiting for the nails to grow out, there are some home care remedies that can help improve the appearance of the ridges. Moisturizing the nails and cuticles daily can relieve dry skin and improve nail health. Additionally, applying a nail ridge filler and nail polish can temporarily hide the ridges. It is also important to avoid behaviours that can damage the nails, such as biting nails or cutting cuticles, and to limit the use of gel manicures, artificial nails, or acrylics, as these can weaken or dry out the nails.
In summary, horizontal nail ridges, or Beau's lines, can be effectively treated and prevented by addressing the underlying cause. This may involve treating medical conditions, addressing nutritional deficiencies, or making lifestyle changes. With proper care and time, smoother and healthier nails can grow in, replacing those with ridges.
