Ridges in your fingernails are usually harmless but can sometimes indicate an underlying health issue. Vertical ridges, or onychorrhexis, are typically caused by the ageing process, but can also be a sign of vitamin or nutrient deficiency, such as a lack of protein, zinc, calcium or vitamin A. Horizontal ridges, or Beau's lines, are often associated with more serious health issues, including severe infections, diabetes, malnutrition, or nutritional deficiencies. If you notice persistent ridges on your nails, it is recommended that you consult a doctor or dermatologist to determine the underlying cause and rule out any potential medical issues.

Vertical ridges on nails are usually a sign of ageing
In some cases, vertical ridges on nails can indicate vitamin or nutrient deficiencies, such as a lack of protein, zinc, calcium, vitamin A, vitamin C, vitamin D, folic acid (vitamin B9), or iron. Certain health conditions, such as inflammatory skin diseases (e.g., psoriasis, lichen planus, eczema), can also cause vertical nail ridges. Additionally, repeated nail trauma during manicures or pedicures and exposure to chemicals in nail polish removers and cuticle softeners can make these ridges more visible.
It is worth noting that vertical ridges on nails are usually harmless and are typically not a cause for concern. However, if you are concerned about the appearance or prominence of these ridges, it is recommended to consult a dermatologist or doctor, who can examine your nails and provide guidance on treatment options.
While vertical ridges are generally age-related, horizontal ridges (Beau's lines) can indicate more serious health issues, such as severe infections, malnutrition, nail injuries, diabetes, or nutritional deficiencies. If you notice deep horizontal ridges on your nails, it is advisable to seek medical advice to rule out any potential underlying conditions.

They can also be a sign of a nutrient deficiency
Vertical ridges on the fingernails, also known as onychorrhexis, are often harmless and are usually caused by the ageing process. However, they can sometimes be a sign of a nutrient deficiency.
Nutritional deficiencies can affect your nails in various ways. For example, a lack of iron in the body can cause vertical nail ridges and koilonychia (spoon nails). Spoon nails have a depression in the middle, as if the centre of the nail has been scooped out, and can hold a drop of water. Iron deficiency can also cause pallor of the nail bed, resulting in a condition known as anaemia.
Zinc deficiency can also impact nail health, causing Beau's lines (deep horizontal ridges) and white spots on the nails. Vitamin A, C, and D deficiencies can lead to a condition called trachyonychia (twenty-nail dystrophy), where the nails become brittle and develop texture changes. Vitamin B9 (folic acid) deficiency may also be a contributing factor to vertical nail ridges.
If you suspect that your vertical nail ridges are due to a nutrient deficiency, it is important to consult a healthcare professional. They can help determine the underlying cause and recommend appropriate treatment or dietary changes. Treating the underlying cause will usually allow for smoother and healthier nails to grow in over time.

Deeper vertical ridges can indicate an underlying medical issue
While vertical ridges on nails are usually harmless and a typical sign of aging, deeper vertical ridges can indicate an underlying medical issue.
When to Seek Medical Advice
If you have deep vertical ridges or other health issues, it is recommended to get a blood test to check for possible deficiencies. If you experience nail changes, it is important to be evaluated by a doctor. A doctor will examine your nails and ask about any other symptoms you may be experiencing. Deeper ridges may be a sign of vitamin or mineral deficiency. For example, iron, folic acid (vitamin B9), protein, zinc, calcium or vitamin A deficiency may cause deeper vertical ridges.
Treatment
Treating or managing the underlying medical condition or nutrient deficiency usually allows smoother, healthier nails to grow in. It may take several months to see a difference, as fingernails grow slowly. If the cause of the deeper ridges is unclear, a dermatologist may take some fingernail clippings to be analysed in a lab for signs of infection.

Onychorrhexis is a condition that causes vertical ridges and brittle nails
Vertical ridges on your fingernails, also known as onychorrhexis, are a common condition that tends to develop as people age. Onychorrhexis is characterised by the presence of vertical ridges and brittle nails that are prone to splitting and breaking. While it is usually harmless, it can sometimes indicate an underlying health issue.
Onychorrhexis is caused by issues with the production of skin cells and keratin, a protein that plays a crucial role in nail growth. As a result, nails become thinner and more brittle with pronounced vertical ridges. These ridges often manifest as thin grooves running along the length of the nail, giving the nail a bumpy texture.
The condition is primarily associated with the ageing process, as cell turnover slows down with age, leading to thinner, more fragile nails. However, it can occasionally be indicative of other health problems. For instance, vitamin and mineral deficiencies, such as a lack of iron, zinc, calcium, or vitamin A, can contribute to the development of onychorrhexis. Additionally, certain health conditions, such as eczema, psoriasis, and other inflammatory skin diseases, can also be factors.
In some cases, onychorrhexis may be hereditary. Witkop syndrome, a genetic disease, can cause vertical nail ridges, along with other nail abnormalities. Furthermore, rheumatological diseases, such as gout, rheumatoid arthritis, and osteoarthritis, which affect the joints and cause deformities, can also impact nail health and potentially lead to onychorrhexis.
While onychorrhexis itself is typically not a cause for concern, it is important to monitor your nails for any additional changes or symptoms. If you suspect an underlying health condition or experience pain, discolouration, or other abnormalities, it is recommended to consult a doctor or dermatologist for further evaluation.

Vertical ridges can be caused by manicures, pedicures, and nail polish remover
Vertical ridges on your fingernails are a common occurrence, especially as you age. They are usually harmless and often appear as people get older due to a slowing of cell turnover. However, in some cases, they can indicate an underlying medical condition or nutrient deficiency.
While vertical ridges are typically age-related, repeated manicures, pedicures, and the use of nail polish remover can also contribute to their formation and visibility. Manicures and pedicures can cause trauma to the nails, especially if not done carefully. The chemicals found in nail polish removers and cuticle softeners can also damage the nail matrix, affecting nail growth and making the ridges more prominent.
The nail matrix is responsible for nail growth, and any issues with the production of skin cells and keratin can lead to vertical ridges. Additionally, certain nutritional deficiencies, such as low levels of protein, zinc, calcium, or vitamin A, can manifest as vertical ridges on the nails. Iron deficiency has also been linked to this condition.
If you are concerned about the appearance of vertical ridges on your nails, it is recommended to consult a dermatologist or doctor. They can examine your nails, assess any other symptoms, and determine if there is an underlying medical cause that requires treatment. In some cases, addressing the underlying condition or nutrient deficiency can lead to smoother and healthier nail growth over time.
While vertical ridges are typically harmless, it is important to pay attention to any changes in your nails and seek medical advice if you have concerns. Proper nail care, including moisturization and gentle buffing, can also help improve the appearance of ridges.
