Ridges in fingernails are usually a sign of aging, as nails can naturally become ridged, dry, brittle, or thick over time. However, they can also indicate other health problems, such as vitamin or mineral deficiencies, or more serious conditions like diabetes, peripheral artery disease, or kidney disease. Horizontal ridges, known as Beau's lines, are often a symptom of an underlying illness, injury, or skin condition that interrupted nail growth. If you notice persistent ridges in your fingernails, it is recommended to consult a dermatologist or healthcare provider to rule out any potential health concerns and determine an appropriate treatment plan.

Ridges in fingernails are usually a sign of aging
Ridges in your fingernails can be harmless, but they can also indicate an underlying health condition. Most of the time, they are a typical sign of aging. As you get older, your nails can naturally become ridged, dry, brittle, or thick. This is due to a slowing of cell turnover, when new skin cells produced below the surface of your skin take the place of dead cells being discarded from the surface.
However, it is important to pay attention to fingernail ridges and other nail changes, as they might be the first signs of a serious medical problem. For example, deep horizontal ridges, called Beau's lines, are often a symptom of serious conditions. They may even stop nail growth until the underlying cause is treated. If Beau's lines appear, acute kidney disease may also be present. Beau's lines can be caused by chronic conditions like diabetes, peripheral artery disease, hypothyroidism, and skin conditions like eczema. They can also be caused by severe zinc deficiency, protein deficiency, or mental and emotional stress.
If the cause of your fingernail ridges is unclear, a dermatologist may take some fingernail clippings to have them analyzed in a lab for signs of infection. If the ridges are the result of a skin condition, a dermatologist can start you on a treatment plan. If you have developed Beau's lines because of diabetes, successfully managing your blood sugar may reduce these horizontal fingernail ridges. Treatment for skin conditions like eczema may include moisturizers for your hands or topical ointments to reduce symptoms. If low levels of minerals or vitamins are the cause, you may be advised to alter your diet or take supplements to boost your levels.
Other nail abnormalities can be harmless. For example, white spots on your fingernails are common and usually do not indicate a serious problem. However, white nails, or leukonychia, can be caused by several things, including trauma, anemia, dietary deficiencies, heart or kidney disease, or even poisoning. If your nails are mostly white with darker rims, this can indicate liver problems, such as hepatitis.

Wavy nails can be a symptom of transient conditions, environmental factors, or immune-based diseases
While wavy nails are not a medical emergency, they can be a symptom of transient conditions, environmental factors, or immune-based diseases.
Transient Conditions
Transient conditions are temporary health issues that can cause wavy nails. For example, a fungal nail infection or injury can lead to nail abnormalities. In addition, as individuals grow older, the levels of natural oils and moisture in the nail plates decrease, making the ridges more prominent.
Environmental Factors
Wavy nails can also be influenced by environmental factors, such as exposure to harsh chemicals or prolonged immersion of the hands in water. Keeping hands moisturized and avoiding prolonged contact with water can help mitigate these effects.
Immune-Based Diseases
In some cases, wavy nails may indicate a more severe underlying immune-based disease. Some of the main diseases associated with wavy nails include rheumatoid arthritis, lichen, metabolic disorders, malnutrition, and fungal diseases. It's important to consult a doctor if you have concerns or if symptoms persist, as a proper diagnosis can be made through further examination and effective therapies can be recommended.
Treatment Options
There are various treatment options available for individuals with wavy nails. These include the use of ointments and lotions based on natural vegetable oils to keep nails soft and hydrated, promoting healing. Additionally, taking biotin supplements and consuming biotin-rich foods can improve nail resistance. Consulting a doctor is advised to determine the underlying cause and devise an appropriate treatment plan.

Wavy nails can be a sign of fungal nail infection or injury
Wavy nails, or onychorrhexis, often occur as a natural part of the ageing process. As people get older, their nails can naturally become ridged, dry, brittle, or thick. However, it can also be a sign of a fungal nail infection or injury, as well as other underlying health conditions.
Fungal nail infections are a common cause of nail discolouration and deformation. If you notice your nails turning yellow, it could be a sign of a fungal infection. As the infection worsens, the nail bed may retract, and nails may thicken and crumble. In rare cases, yellow nails can indicate severe thyroid disease, lung disease, diabetes, or psoriasis.
Nail injuries can also cause waviness. This can be caused by trauma to the nail, such as dropping something heavy on your finger, slamming your finger in a door, or exposure to extreme cold. Picking at your nails or using strong chemicals can also damage your nail matrix, affecting how your nails grow.
If you notice waviness in your nails, it is important to pay attention to any other nail changes or symptoms. While nail abnormalities are often harmless, they can sometimes be a sign of a more serious medical problem. If you are concerned, it is recommended to consult a dermatologist or healthcare provider for further advice and treatment options.
To maintain nail health, it is important to practice good hygiene and self-care practices. This includes keeping your nails clean, moisturized, and trimmed. Wearing gloves while handling chemicals or washing dishes can also help protect your nails from potential damage.

Onychorrhexis is a condition that causes vertical ridges and splitting
Wavy fingernails, or vertical ridges and splitting, are often a sign of onychorrhexis. This is a common nail disorder that can affect both finger and toenails. The condition is characterised by longitudinal ridging and splitting of the nails, with the ridges appearing as thin grooves running vertically along the length of the nail. While onychorrhexis is usually nothing to worry about, it can sometimes indicate an underlying health problem.
Onychorrhexis is typically a result of the ageing process, with nails naturally becoming ridged, dry, brittle, and prone to splitting as people get older. However, it can also be caused by other factors, such as nutritional deficiencies, medical conditions, or external trauma. Nutritional deficiencies, such as a lack of biotin, iron, protein, folic acid, or other vitamins, can lead to nail growth problems and weakened nails. Certain medical conditions, including hypothyroidism, psoriasis, eczema, and Witkop syndrome, can also contribute to the development of onychorrhexis. Additionally, external factors like exposure to chemicals or physical trauma can damage nails and lead to the condition.
While onychorrhexis is often a cosmetic issue, it is important to be aware of potential underlying causes. If you notice sudden changes in your nails, or if you have other symptoms such as pain or fatigue, it is recommended to consult a doctor. A healthcare provider will typically examine your nails, inquire about your medical history, dietary habits, and any recent trauma to the nails, and may order blood tests to check for nutritional deficiencies or medical conditions.
Treatment for onychorrhexis focuses on addressing the underlying causes. For example, if the condition is caused by an inflammatory disorder, a doctor may recommend topical corticosteroids or injections to reduce inflammation. Moisturising products, such as vitamin E oil, petroleum jelly, or olive oil, can also be applied to the hands and nails to improve nail health. Additionally, maintaining proper nail care practices, such as keeping nails trimmed and avoiding excessive use of nail polish and removers, can help prevent further damage and maintain healthy nails.
In summary, onychorrhexis is a condition that causes vertical ridges and splitting of the nails, often due to ageing, nutritional deficiencies, medical conditions, or external factors. While it is usually a cosmetic concern, it can sometimes indicate an underlying health issue, and it is important to consult a doctor if you have any concerns or notice sudden changes in your nails. Treatment options are available to improve nail health and address any underlying causes.

If the cause of fingernail ridges is unclear, a dermatologist may analyse nail clippings for signs of infection
Fingernail ridges are usually harmless and are a typical sign of ageing. Vertical ridges, or longitudinal striations, are a natural part of ageing, sometimes developing after biting or picking at your nails. They can also be caused by vitamin or mineral deficiencies, or dehydration of the nail plate. Horizontal ridges, called Beau's lines, may be a sign of a more serious condition, such as diabetes, acute kidney disease, or peripheral vascular disease. They can also be caused by physical trauma to the nail, such as closing a door on your finger.
If the cause of fingernail ridges is unclear, a dermatologist may take nail clippings to be analysed in a lab for signs of infection. This is because fingernail ridges can often be a sign of other health problems. Treatment will then focus on the underlying cause of the changes to the nails. For example, if you have developed Beau's lines because of diabetes, successfully managing your blood sugar may reduce these horizontal ridges. If the cause is a vitamin or mineral deficiency, you may be advised to alter your diet or take supplements.
If you are concerned about the appearance of your nails, it is recommended to see a doctor or dermatologist. They can examine your nails, review your medical history, and order diagnostic tests to determine the underlying cause of any ridges. They can also advise on treatments to improve the appearance and health of your nails.
It is important to pay attention to fingernail ridges and other nail changes, as they might be the first signs of a serious medical problem. Changes to the shape, texture, or colour of your fingernails may be a sign of an underlying condition that requires medical attention.

Frequently asked questions
Wavy fingernails, or onychorrhexis, are typically characterised by vertical ridges that run from the tip of the fingernail to the cuticle. This condition can also cause nails to become brittle and break more easily.
Onychorrhexis is most commonly caused by the ageing process, as cell turnover slows down. However, it can also be a sign of underlying health conditions, such as heart and circulatory diseases, nutrient deficiencies, or rheumatological diseases.
While onychorrhexis is often just a cosmetic concern, it is important to address any underlying health conditions that may be contributing to the condition. Maintaining good nail hygiene and using moisturisers can help keep your nails healthy.
Beau's lines are deep horizontal ridges that run across the fingernails or toenails. Unlike vertical ridges, these are often a symptom of more serious conditions, such as chronic illnesses, injuries, or skin conditions that interrupted nail growth.
While there is no direct treatment for Beau's lines, addressing the underlying cause is crucial. This may involve treating any underlying illnesses, managing stress, or seeking medical advice for conditions such as diabetes, peripheral artery disease, or skin conditions like eczema.
