Ridges in your nails are visible lines or dents that can run vertically or horizontally. While they are usually harmless, they can sometimes indicate a health condition or nutrient deficiency. Vertical ridges, which are often a sign of aging, can also be caused by skin conditions such as dry skin or eczema. Horizontal ridges, on the other hand, can point to issues like malnutrition, nail injury, or Beau's lines, which are associated with more serious health concerns. It is important to pay attention to any nail changes and consult a healthcare provider to determine the underlying cause and appropriate treatment.

What You'll Learn
Ageing
Ridges in your nails are usually harmless but can indicate various health conditions. Vertical ridges, which run from the tip of the fingernail down to the cuticle, are often a sign of ageing. As people grow older, their nails naturally get thinner and more brittle, and vertical ridges may become more pronounced over time. According to research from 2022, ridges are typically caused by ageing.
Vertical nail ridges, also known as longitudinal ridges, are common among older individuals. These lines are usually harmless and not considered dangerous. However, they may indicate an underlying medical issue in some cases. While vertical ridges are typical signs of ageing, they can also be caused by other factors, including nutritional deficiencies, skin conditions, and improper nail care.
Nutritional deficiencies, such as iron, zinc, vitamin A, C, and D deficiencies, can contribute to the formation of vertical ridges. Certain health conditions, such as hypothyroidism, can also cause these ridges. People with hypothyroidism may experience thick, brittle nails with vertical ridges that crumble or break easily. Additionally, skin conditions like eczema or very dry skin can lead to vertical lines on the nails.
To improve the appearance of nails with ridges, individuals can incorporate daily moisturising into their nail care routine. Applying moisturiser to the nails and cuticles can help relieve dry skin and eczema. For individuals with diabetes or neuropathy, it is essential to consult a healthcare provider for specific foot care recommendations. Additionally, taking biotin supplements may promote nail growth and improve the overall appearance of the nails.
While vertical ridges are typically associated with ageing, it is important to monitor any changes in the nails. If you notice new ridges or lines, it is recommended to consult a healthcare provider to determine the underlying cause and receive appropriate treatment if necessary.

Thyroid disease
Ridges in your nails are usually harmless but can indicate different things about your health. Vertical ridges are often a sign of aging, while horizontal ridges can point to malnutrition, serious nail injury, or Beau's lines. According to research, ridges are usually caused by aging. However, they can also be a sign of improper nail care, nail trauma, vitamin deficiencies, or a more serious underlying medical condition.
If you have a thyroid problem, you can optimise your thyroid hormone levels with thyroid hormone replacement medication. This type of medication often improves or resolves related nail problems. Taking iron or zinc supplements, with a doctor's guidance, may also help improve nail health if you have a deficiency. However, it takes several months for your nails to grow out, and it takes time to see changes in your nails.
If you are concerned about the appearance of your nails, it is recommended to consult a doctor or dermatologist, who can help determine the underlying cause and provide appropriate treatment.

Skin conditions
Vertical nail ridges are commonly associated with the natural ageing process. As we get older, our nails may become thinner and more brittle, and vertical ridges can become more pronounced. This is due to a slowing of cell turnover, where new skin cells produced below the skin's surface rise up to replace dead cells being discarded from the surface.
However, vertical nail ridges can also indicate underlying skin conditions, such as:
- Dry skin, particularly when accompanied by dehydration of the nail plate. Applying moisturizer to the nails and cuticles daily can help alleviate this.
- Eczema, which can be prevented by avoiding excessive hand washing, as this strips the skin of its natural oils and emollients.
- Psoriasis, lichen planus, and other inflammatory skin conditions.
- Witkop syndrome, a hereditary genetic disease that can lead to vertical ridging in fingernails and toenails.
If you notice vertical nail ridges accompanied by other symptoms, it is recommended to consult a dermatologist or healthcare provider to determine the underlying cause and receive appropriate treatment.

Vitamin deficiencies
Ridges in your nails are usually harmless but can indicate vitamin deficiencies or more serious health conditions. Vertical ridges are often a sign of aging, while horizontal ridges can point to issues like malnutrition, serious nail injury, or
Zinc deficiency can cause Beau's lines and white spots on your nails. Vitamin D plays a crucial role in supporting the immune system, and its deficiency can lead to frequent illnesses or infections. Additionally, vitamin B7, also known as biotin, is highly recommended to aid in nail health, although more research is needed to understand its full benefits.
If you notice sudden changes in your nails, especially the development of dark or discolored ridges, it is important to consult a healthcare professional. They can help determine the underlying cause and provide appropriate treatment or recommendations.

Nail trauma
Ridges in your nails are usually harmless but can indicate different things. Vertical ridges are often a sign of aging, while horizontal ridges can point to issues like malnutrition, serious nail injury, or Beau's lines. Beau's lines are deep horizontal ridges that may suggest a serious underlying condition. They can stop nail growth until the underlying condition is treated.
Repeated trauma to toenails, caused by ill-fitting shoes, can lead to deformities in the nails. These deformities may resemble a fungal infection, with thickened or discolored nails that can lift away from the nail bed. Nail biting is a common habit that can cause trauma to the nails and is a leading cause of acute paronychia, a bacterial infection that causes swelling and irritation.
If you experience nail trauma, your doctor can examine the injury and determine the best course of action. Treatment depends on the type and severity of the injury. Minor nail bed injuries, including subungual hematomas, often heal on their own, but more severe cases may require medical treatment. If the trauma affects the nail matrix, the tissue inside the cuticle where new nail growth originates, a ridge or split can develop. If the matrix heals normally, this deformity will eventually disappear as the nail regrows.
