Ridges, lines, and other abnormalities in your nails can be indicative of underlying health conditions. Beau's lines, for example, are deep horizontal ridges that may suggest a serious condition and can halt nail growth until the underlying cause is addressed. On the other hand, melanonychia is characterized by brown or black lines in your nails, which may be caused by trauma, nutritional deficiencies, medication side effects, or other health conditions. It's important to consult a healthcare provider if you notice any new or unusual symptoms, as they can provide a thorough examination and determine the appropriate course of action.

Melanonychia: Black or brown lines that may be caused by trauma, nutritional deficiency, medication, or cancer
Melanonychia is characterised by black or brown lines that appear on the nail plate. These lines are usually vertical and can affect one or multiple nails on the fingers and toes. They can occur naturally in people with a dark complexion, but they may also be caused by trauma, nutritional deficiency, medication, or cancer.
Melanonychia occurs when pigment cells, called melanocytes, deposit melanin into the nail. Melanin is the brown-coloured pigment that gives skin its colour. Melanonychia can be caused by two primary processes: melanocytic activation and melanocytic hyperplasia. Melanocytic activation involves an increase in the production and deposits of melanin in the nail, without an increase in pigment cells. Causes of melanocytic activation include trauma, nutritional deficiency, and medication. On the other hand, melanocytic hyperplasia is an increase in pigment cells in the nail bed, which can be benign or malignant.
Trauma is one of the most common causes of melanonychia. This can include nail injury, such as hitting the nail or biting your nails, or prolonged pressure. Certain medications can also cause melanonychia, including antiretroviral medications and phototherapy (light therapy). Additionally, deficiencies in vitamins B12 and D, and protein can lead to melanonychia.
In some cases, melanonychia may be a sign of cancer, specifically nail melanoma or subungual melanoma. This is a serious form of skin cancer that can cause a black or brown band on the nail, often appearing on the dominant thumb or big toe. Other signs of melanoma include a bump under the nail, nail splitting, lifting, darkened skin around the nail, and a horizontal stripe on the nail. If you notice any of these signs, it is important to consult a healthcare professional for a thorough examination and diagnosis.
While melanonychia may resolve on its own and grow out with the nail, it is always a good idea to consult a healthcare provider if you notice any changes in your nails, especially if there is no obvious cause. A doctor can perform exams, such as a dermatoscopic exam or a biopsy, to determine whether melanonychia is malignant and provide appropriate treatment options.

Beau's lines: Horizontal ridges that may be caused by chronic conditions, vitamin or nutrient deficiencies, or previous illnesses
Beau's lines are horizontal ridges that run across the nail plate. They are not harmful but are usually a sign of an underlying illness or injury that interrupted your nail growth a few weeks or months ago. They can also be caused by vitamin or nutrient deficiencies.
The thickness and number of Beau's lines can indicate the cause. For instance, a single Beau's line on one nail may indicate an injury that affected only one finger or toe. Beau's lines on all nails can mean that an illness or stress caused them. Multiple Beau's lines on each nail may mean that an injury or illness occurred more than once. Thicker Beau's lines may indicate that an illness or trauma lasted a long time.
Chronic conditions that can cause Beau's lines include uncontrolled diabetes, peripheral artery disease (PAD), hypothyroidism, Raynaud's phenomenon, and skin conditions. Certain nutritional deficiencies, such as a lack of zinc, iron, biotin, vitamin B12, vitamin D, or protein, can also result in Beau's lines.
If you notice Beau's lines and are unsure of the cause, consult a healthcare provider to rule out any possible health conditions. Beau's lines will usually grow out after you recover or receive treatment for the underlying cause, which can take about six months. You can temporarily hide the ridges by applying a nail ridge filler and nail polish, but use nail products with caution as some can weaken or damage nails.

Vitamin B12, vitamin D, and protein deficiencies: Dark lines may appear due to these deficiencies
Dark lines under your nails can be indicative of various health conditions. One of the possible causes is melanonychia, which occurs when pigment cells, known as melanocytes, deposit melanin into the nail, resulting in brown or black stripes. This condition can develop due to several factors, including nail trauma, nutritional deficiencies, medication, and other health conditions. It is important to consult a doctor if you notice any such discolouration, as it may indicate underlying health issues.
One specific type of melanonychia is longitudinal melanonychia, characterised by dark stripes running along the length of the nail. This can occur in individuals with a darker complexion or due to increased melanin production. While it may not always indicate a serious condition, it is crucial to seek medical advice to rule out any potential concerns.
Vitamin B12, vitamin D, and protein deficiencies are among the possible causes of dark lines in nails. These nutritional deficiencies can lead to melanonychia, resulting in the appearance of dark stripes. Addressing these deficiencies through dietary changes or supplements may help alleviate the issue. However, it is important to consult a healthcare professional for personalised advice and an accurate diagnosis.
In addition to nutritional deficiencies, other potential causes of dark lines under the nails include nail injuries, infections, and cancer. Nail trauma or injury can lead to the formation of red or brown spots underneath the nails. Infections can also cause discolouration and should be examined by a doctor. Additionally, dark vertical lines could indicate nail melanoma, emphasising the importance of seeking medical advice for an accurate diagnosis and appropriate treatment plan.
While this information provides insight into the potential causes of dark lines under the nails, it is crucial to consult a healthcare professional for personalised advice and an accurate diagnosis. Self-diagnosis should be avoided, and any concerns about nail discolouration or other symptoms should be discussed with a doctor, who can perform the necessary examinations and provide appropriate treatment recommendations.

Iron deficiency: Can cause vertical nail ridges and spoon-shaped nails
Ridges in your fingernails or toenails can be indicative of a current or past illness, or a nutrient deficiency. Beau's lines, for example, are deep horizontal ridges that may suggest a serious underlying condition. They are often harmless and go away once your nails have grown out, but they could indicate acute kidney disease or even cancer. It is important to consult a healthcare provider to rule out any possible health conditions.
Iron deficiency is one such nutritional deficiency that can cause changes to your nails. It can lead to vertical nail ridges and koilonychia, commonly known as spoon nails. Spoon nails have a noticeable depression in the middle, almost as if the center of the nail was scooped out. In some cases, the indentation is deep enough to hold a drop of water.
Spoon nails are often a sign of iron deficiency anemia. This can be caused by an inability to absorb iron, a diet lacking in iron-rich foods, or conditions such as celiac disease, cancer, or intestinal bleeding. Excessive menstruation can also lead to iron deficiency in women. In addition, people who follow a vegetarian diet may be at a higher risk of iron deficiency, as well as those living at high altitudes.
To treat spoon nails, it is essential to address the underlying cause. Consulting a healthcare provider is recommended, as they can provide tests to determine the root cause and suggest appropriate treatment options. This may include dietary changes or iron supplements, always taken under the guidance of a healthcare professional. It takes several months for nails to grow out, so it will take time to see improvements in the appearance of your nails.

Home care: Applying moisturizer to nails and cuticles can improve the appearance of nails with ridges
Ridges in your fingernails can be harmless and caused by dry skin or a deficiency in protein, calcium, zinc, or vitamin A. However, deep horizontal ridges, known as Beau's lines, may indicate a more serious underlying condition, such as mumps, thyroid disease, kidney disease, diabetes, or syphilis. Beau's lines can also be caused by certain medications, particularly chemotherapy drugs.
To improve the appearance of nails with ridges, you can apply moisturizer to your nails and cuticles. Moisturizing your nails can keep them from becoming brittle and protect the nail plate from air and water damage. There are two common methods for moisturizing your nails:
- Apply a cream or ointment, such as petroleum jelly, to your hands, cuticles, and nail plates.
- Soak your nails in oil, such as bath oil or warm olive oil, for about 20 minutes.
If you have nail polish on, you must remove it before moisturizing your nails, as the polish acts as a barrier. Additionally, acetone, commonly used to remove nail polish, can dehydrate your nails and the surrounding skin, making them brittle.
When moisturizing your nails, you can use the same cream that you would use on your hands. However, there are also nail- and cuticle-specific creams and oils available. It is recommended to moisturize your nails immediately after they have been exposed to water. Exfoliating your nails with glycolic acid can also help improve dryness.
