Ridges in fingernails can be caused by various factors, ranging from aging to underlying medical conditions. While vertical ridges are usually harmless and common in older adults, deep horizontal ridges, or Beau's lines, can indicate a serious health issue. These grooves may signal that an illness, injury, or skin condition interrupted your nail growth. In some cases, deep vertical grooves may be a sign of vitamin deficiencies, iron deficiency, or even more serious conditions like Witkop syndrome, a hereditary genetic disease.

Horizontal nail grooves, known as Beau's lines, can be caused by trauma or damage to the nail matrix
Horizontal nail grooves, also known as Beau's lines, can appear on one nail or multiple nails. They are caused by trauma or damage to the nail matrix, which is the part of your nail that produces new cells. This trauma or damage can be caused by physical injury, such as slamming your finger in a door or dropping something heavy on your finger, or by underlying health conditions.
The appearance of Beau's lines can vary depending on the severity and duration of the nail growth disruption. They can manifest as indentations or grooves that run horizontally across the nail, with the depth of the ridge indicating the severity of the disruption and the width showing how long it lasted. In some cases, Beau's lines may be accompanied by other symptoms such as bruising, discoloration, or soreness in the affected nail.
There are several factors that can contribute to the development of Beau's lines by disrupting nail growth. These factors include certain health conditions, medications, and injuries. Health conditions that can lead to Beau's lines include infections such as strep, pneumonia, COVID-19, and other illnesses. Additionally, chronic conditions that interfere with blood flow to the nail matrix, such as peripheral artery disease, hypothyroidism, and Raynaud's phenomenon, can also cause Beau's lines.
Medications, particularly chemotherapy drugs, are also known to trigger Beau's lines. Chemotherapy targets fast-growing cells, including those in the nail matrix, which can temporarily slow nail production and result in the formation of grooves or ridges. Other medications have been linked to Beau's lines as well. If Beau's lines appear on all nails, it likely indicates a systemic issue or treatment, such as chemotherapy. On the other hand, if only one nail is affected, it probably resulted from a localized injury or poor blood flow.
While Beau's lines themselves are not harmful, they can be a sign of an underlying health issue. Therefore, it is important to consult a healthcare provider if you notice Beau's lines and are unsure of the cause. Treating the underlying cause can help prevent new lines from forming and promote healthier nail growth.

Vertical nail grooves are common with age and can indicate a vitamin or nutritional deficiency
Vertical nail grooves, also known as nail depressions, are a common occurrence with age. They are usually slight and occur due to changes in the nail matrix and nail bed. While these grooves are typically harmless, they can, in some cases, indicate an underlying health condition.
Nail depressions can manifest differently for each individual, much like fingerprints. They can appear as vertical or horizontal grooves and are more common in seniors. While vertical grooves are usually benign, horizontal grooves, also known as Beau's lines, can suggest a more serious condition. Beau's lines are deep horizontal ridges that can be caused by chronic conditions, injuries, or trauma to the nail matrix, such as slamming your finger in a door or dropping something heavy on it.
Vertical nail grooves can become more prominent with age and may indicate a health condition such as dermatitis, eczema, anaemia, or a vitamin or nutritional deficiency. Nail delamination, dryness, and colour changes may accompany these conditions. It is important to pay attention to nail changes as they can be early indicators of underlying health issues. Vitamins and nutrients are crucial for normal nail growth, and any deficiencies can manifest through nail abnormalities.
If you notice prominent vertical nail grooves, it is recommended to consult a healthcare provider or dermatologist to determine the underlying cause. They may examine your nails, take a health history, and order blood or urine tests to check for vitamin deficiencies, kidney disease, diabetes, or other potential health problems. While there are cosmetic procedures to mask minor nail grooves, it is essential to address any underlying health issues first.

Deep nail grooves may be a sign of a health condition such as dermatitis, eczema, or anaemia
Deep nail grooves, also known as Beau's lines, can be a sign of a health condition such as dermatitis, eczema, or anaemia. Beau's lines are horizontal grooves or dents that run across fingernails or toenails. They are typically caused by trauma or damage to the nail matrix, such as dropping something heavy on your finger or undergoing aggressive manicures or artificial nail treatments. While Beau's lines are often harmless, they can sometimes indicate more serious underlying health issues.
Vertical nail grooves, on the other hand, are usually a normal sign of aging. However, prominent vertical grooves can indicate certain health conditions such as dermatitis, eczema, or nutritional deficiencies. Additionally, deep vertical grooves can be a sign of anaemia, as iron deficiency can cause thin, spoon-shaped nails.
It is important to pay attention to nail changes and consult a dermatologist if you notice any unusual symptoms. A dermatologist can examine your nails, take a health history, and order any necessary tests to determine the underlying cause of deep nail grooves. Treating the underlying cause will help new, smooth nails to grow again.
In some cases, deep nail grooves may be a sign of more serious medical conditions. Horizontal grooves, for example, can indicate anaemia, cardiovascular issues, thyroid problems, syphilis, or diabetes. Therefore, it is always advisable to seek professional medical advice if you are concerned about any changes in your nails.

Ridges in fingernails can be a sign of kidney disease, diabetes, or nutritional deficiencies
Ridges in your fingernails can be a sign of various health conditions, ranging from ageing to more serious conditions like kidney disease, diabetes, or nutritional deficiencies. These ridges can be either vertical or horizontal and are usually harmless. However, it is important to monitor them as they may indicate an underlying health problem.
Vertical ridges, also known as longitudinal ridges or bands, commonly develop in older adults due to a potential slowing of cell turnover. They are typically not dangerous and can be a normal part of the ageing process. On the other hand, horizontal ridges, known as Beau's lines, can indicate a more serious condition. Beau's lines are deep grooves that run across the fingernails horizontally and can be caused by various factors, including injury, chemotherapy, artificial nails, or severe illnesses such as COVID-19 or pneumonia.
If you notice ridges in your fingernails, it is recommended to consult a healthcare provider to determine the underlying cause. Your doctor may examine your nails, ask about other symptoms, and possibly order urine and blood tests to check for any health conditions or deficiencies. Treatment options may include addressing the underlying cause, moisturising your nails, or seeking the advice of a dermatologist for further recommendations.
While ridges in fingernails can be a sign of health problems, they can also be caused by external factors. For example, using artificial nails or gel manicures for extended periods can lead to nail damage and the formation of ridges. Peeling nails can also result from picking off nail polish or pressing on your nails too firmly. In these cases, it is advisable to take a break from such practices and focus on nail care routines that involve moisturising and trimming.

Nail pitting or peeling can result from trauma to the nail, such as picking off nail polish
Fingernail ridges are usually a sign of aging, as vertical ridges commonly develop in older adults. However, deep horizontal ridges, known as Beau's lines, could indicate a more serious underlying condition. Chronic conditions such as vitamin deficiencies, diabetes, or kidney disease can cause Beau's lines.
Beau's lines are characterised by deep horizontal grooves that run across the fingernails or toenails. They can be caused by trauma or damage to the nail matrix, such as dropping something heavy on your finger or toe, or even from something as simple as a manicure.
Nail pitting, or peeling, can also be the result of trauma to the nail, including picking off nail polish or pressing on your nails. Nail pitting is characterised by small indentations or depressions in the nails, which may be an indicator of a problem with the nail matrix. According to Dr Ted Lain, a board-certified dermatologist, it is usually an inflammatory skin condition that may lead to pitting of the nails. Nail psoriasis, an autoimmune disease, is one such condition that can cause nail pitting.
If you are experiencing nail pitting, it is recommended to see a board-certified dermatologist who can diagnose and prescribe treatments. While you can gently buff and apply nail polish to improve the appearance of your nails, this does not address the underlying cause. Treatments for nail pitting can take several months to show results, and you may need to try different treatments to find one that works for you. In the meantime, keeping your nails short and wearing gloves when doing manual work can help prevent further issues.
