Ridges on your fingernails can be a sign of a current or past illness, or a nutrient deficiency. They can also be caused by previous trauma to the nail, such as an injury or the use of artificial nails. Vertical ridges, which run from the tip of the fingernail down to the cuticle, are often a sign of aging. Horizontal ridges, on the other hand, can point to issues like malnutrition, serious nail injury, or a condition called Beau's lines, which can be caused by chemotherapy, peripheral vascular disease, or severe illness with a high fever. While nail ridges are usually harmless, they can sometimes indicate a more serious health condition.

What You'll Learn
Vertical nail ridges are often a sign of ageing
Ridges in your nails are visible lines or dents that can run either vertically (up and down) or horizontally (across). While they are usually harmless, they can sometimes indicate a health condition or a previous injury to your nail. Vertical nail ridges, also known as longitudinal ridges, are often a sign of ageing. As people get older, they commonly develop vertical ridges on their nails, and these lines are not dangerous.
Onychorrhexis is a condition that causes vertical ridges on your fingernails. It is often associated with ageing but can also indicate an underlying health problem. Conditions that can cause onychorrhexis include hypothyroidism, liver disease, and chronic kidney disease. Additionally, certain nutritional deficiencies, such as an iron deficiency, can lead to vertical nail ridges.
While vertical nail ridges are typically age-related, it is important to monitor your nails for any other changes. Vertical ridges accompanied by texture changes in your nails may be caused by a medical condition such as trachyonychia (twenty-nail dystrophy). If you experience nail changes, it is recommended to consult a doctor or dermatologist for evaluation and treatment.
To improve the appearance of your nails, you can apply moisturizer to your nails and cuticles daily to relieve dry skin. At bedtime, applying a skin cream to your hands and wearing thin cotton gloves while sleeping can also help. While there is no guaranteed way to prevent nail ridges, maintaining regular visits to your healthcare provider can help address any underlying health conditions that may be contributing factors.

They can also indicate a vitamin or nutrient deficiency
Vertical ridges on nails can sometimes indicate a vitamin or nutrient deficiency. These ridges can be a sign of an eating disorder or low levels of nutrients such as iron, folic acid (vitamin B9), or protein. They can also be caused by inflammatory skin conditions, such as psoriasis and lichen planus, or by repeated trauma to the nails during manicures or pedicures. Chemicals found in nail polish removers and cuticle softeners can also make vertical nail ridges more visible.
If you notice vertical ridges on your nails, it is important to consult a doctor or dermatologist to determine the underlying cause and rule out any potential health issues. A doctor will examine your nails and ask about any other symptoms you may be experiencing. They may also order urine and blood tests to check for any underlying conditions, such as kidney disease, diabetes, or nutritional deficiencies.
Treatment for vertical nail ridges will depend on the underlying cause. If the ridges are caused by a vitamin or nutrient deficiency, your doctor may advise you to alter your diet or take supplements to boost your levels. Moisturizing your nails and keeping them trimmed can also help to improve their appearance and prevent further damage.
While vertical ridges are often a harmless sign of aging, they can sometimes indicate an underlying medical condition. Paying attention to any changes in your nails and seeking medical advice when necessary is important for maintaining overall health and well-being.

Horizontal nail ridges may suggest a serious condition
Horizontal nail ridges, also known as Beau's lines, may indicate a serious underlying condition. Beau's lines appear as deep horizontal ridges that can halt nail growth until the underlying cause is addressed. While they are often harmless, these ridges can sometimes indicate a more serious medical problem that requires prompt attention.
Beau's lines can be caused by various factors, including malnutrition, serious nail injury, or certain nutrient deficiencies, such as zinc deficiency. In some cases, they may be indicative of peripheral vascular disease (PAD), diabetes, or even acute kidney disease. Therefore, it is important to consult a doctor or dermatologist if you notice persistent or concerning horizontal nail ridges, especially if accompanied by other symptoms.
A doctor can examine your nails and conduct the necessary tests to determine the underlying cause. If the horizontal ridges are due to nutritional deficiencies, altering your diet or taking supplements may be recommended. For instance, if Beau's lines are caused by diabetes, successful management of blood sugar levels may help reduce these horizontal nail ridges. Similarly, treating an underlying skin condition, such as eczema, through moisturizers or topical ointments, can also improve the appearance of your nails.
While home care, such as moisturizing and trimming your nails, can help improve their appearance, it is crucial to address any potential health issues that may be causing the horizontal ridges. If the cause of the ridges is unclear, a dermatologist may take nail clippings for laboratory analysis to identify any infections or other underlying conditions.

Horizontal ridges can be caused by trauma to the nail
Horizontal ridges on the nails, also known as Beau's lines, are often caused by trauma to the nail matrix, which is located just behind the cuticle. This trauma can be mechanical or physical, such as dropping something heavy on your finger, slamming your finger in a door, or exposure to extreme cold. Even manicures or artificial nails can cause such trauma.
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. Additionally, severe emotional stress, like a divorce, death in the family, or job loss, can be a factor. These emotional stressors can affect nail health and growth, resulting in horizontal ridges.
It is important to note that while Beau's lines are typically benign, they can sometimes indicate more serious conditions. For example, they may be a symptom of acute kidney disease or even melanoma. Thicker Beau's lines may suggest that an illness or trauma was prolonged. Therefore, if you notice persistent or pronounced horizontal ridges on your nails, it is advisable to consult a healthcare professional to rule out any potential health concerns.
Treating the underlying cause of Beau's lines is crucial to restoring smooth nail growth. While there is no specific treatment for the lines themselves, addressing any underlying health issues can prevent their recurrence. In the meantime, you can temporarily hide the ridges by applying a nail ridge filler and nail polish. However, exercise caution when using nail products, as some can weaken or damage your nails.

Ridges on nails can be treated by moisturising and gentle buffing
Ridges on nails are usually harmless but can sometimes indicate a health problem. They can be caused by ageing, nutrient deficiencies, or skin conditions. Vertical ridges, which run from the tip of the fingernail to the cuticle, are a common sign of ageing. Horizontal ridges, also known as Beau's lines, can be caused by malnutrition, serious nail injuries, or underlying health conditions such as diabetes or kidney disease.
If you notice new ridges or other changes in your nails, it is important to consult a healthcare provider to determine the underlying cause. Treating the underlying cause is the first step in improving the appearance of your nails. For example, if Beau's lines are caused by diabetes, managing blood sugar levels may help reduce these horizontal ridges.
While ridges on nails may not always require medical treatment, there are some home care and lifestyle changes that can help improve their appearance. Here are some ways to treat and reduce ridges on your nails:
Moisturising
Moisturising your nails and hands can help reduce ridges, especially if they are caused by skin conditions such as eczema. Moisturising can help improve skin hydration and nail flexibility, making the ridges less noticeable. Look for moisturisers or topical ointments that are suitable for your skin type and apply them regularly to your hands and nails.
Gentle Buffing
Some dermatologists suggest gently buffing your nails to smooth out the ridges. However, it is important to be cautious and gentle during the process to avoid further damage to your nails. If you are unsure, it is best to consult a dermatologist for guidance on nail buffing techniques and frequency.
Nutritional Supplements
If nutrient deficiencies are causing your nail ridges, addressing these deficiencies through dietary changes or supplements can help. For example, zinc deficiency can cause Beau's lines and white spots on your nails, while iron deficiency can lead to vertical nail ridges and koilonychia (spoon nails). Consult a healthcare provider to determine if you need supplements and for guidance on appropriate dosages.
Nail Care Routine
Taking a break from manicures and giving your nails time to grow and strengthen can help reduce ridges. When applying treatments or polishes, look for products that contain keratin to help strengthen your nails. Additionally, avoid picking your nails, jamming the cuticle back, or causing trauma to the nail matrix, as these actions can lead to horizontal ridges.
