Ridges, dryness, and hardness in your fingernails can be caused by various factors, ranging from aging to underlying health conditions. Vertical ridges, which run from the tip of the fingernail to the cuticle, are usually harmless and are often a normal sign of aging due to a slowing of cell turnover. On the other hand, horizontal ridges, known as Beau's lines, may indicate a more serious underlying condition, such as kidney disease, diabetes, or vitamin deficiencies. Dry and brittle nails can be caused by a lack of moisture due to frequent washing and drying, while soft and brittle nails are caused by too much moisture from overexposure to detergents and nail polish remover. Additionally, nutrient deficiencies, such as iron deficiency or a vitamin B12 deficiency, can also cause changes in nail texture and color. Proper nail maintenance, including the use of moisturizers, nail conditioners, and cuticle care, can help keep your nails healthy and strong.

Ridges in nails can be a sign of a current or past illness, vitamin or mineral deficiency, or injury
Ridges in your fingernails can be caused by a variety of factors, and they can often be a sign of a current or past illness, vitamin or mineral deficiency, or injury. Vertical ridges, which run from the tip of the fingernail to the cuticle, are usually a normal part of the ageing process and are generally not a cause for concern as long as they are not accompanied by other symptoms. They can, however, also be caused by decreased circulation to the fingertips, stripping nails with solvents during manicures, or certain dermatological conditions.
On the other hand, horizontal ridges, also known as Beau's lines, are often indicative of more serious underlying conditions. These can include malnutrition, serious nail injury, or, in some cases, acute kidney disease or diabetes. Beau's lines may even stop nail growth until the underlying condition is treated. It is important to note that medications, particularly chemotherapy drugs, are a common cause of these horizontal ridges.
If you are experiencing nail changes due to an injury, it is recommended to wait a few weeks to see how the nail and finger heal before deciding to see a doctor. However, if the injury results in red or brown spots under the nails, or other symptoms such as discoloration, pain, or abnormal growth, it is advised to consult a doctor as soon as possible.
Additionally, vitamin and mineral deficiencies can also contribute to nail ridges. For example, vitamin B12 and iron deficiencies can lead to changes in nail colour and the development of spoon nails, where the nail appears concave. Furthermore, heart and circulatory diseases, which affect nutrient and oxygen delivery to the nails, can result in nail growth problems.
In summary, while vertical ridges are often age-related, horizontal ridges are more likely to indicate an underlying issue. If you are concerned about the appearance of ridges on your fingernails, it is always best to consult a doctor or dermatologist, who can examine your nails and advise on any necessary treatment or lifestyle changes.

Dry and brittle nails are often caused by repeated washing and drying of the fingernails
To prevent this, it is recommended to moisturize your hands and nails after washing them. It is also suggested to moisturize your hands, feet, and nails before going to bed to keep them hydrated as you sleep. When doing household chores, wearing gloves can keep your hands dry and protect your nails from harsh chemicals.
In addition to frequent washing and drying, other factors can also contribute to dry and brittle nails. For example, people are more likely to experience dry nails in hot, dry environments or during the winter months. Age-related changes in nail structure can also lead to nails becoming thinner and more brittle.
Underlying health conditions can also play a role in nail brittleness. For instance, iron deficiency, hypothyroidism, and anemia have all been linked to brittle nails. Additionally, vitamin and mineral deficiencies, as well as conditions such as diabetes and malnutrition, can manifest as ridges in the fingernails.
If you are experiencing persistent or severe nail brittleness, it is advisable to consult a doctor or dermatologist. They can help determine if there are any underlying health issues contributing to the condition of your nails and provide appropriate treatment or advice.

Hypothyroidism can cause thick, brittle nails with vertical ridges
Fingernail ridges are often harmless and are a typical sign of aging. However, they can sometimes indicate underlying health issues. Vertical ridges, which are usually harmless, are often a sign of aging, while horizontal ridges, called Beau's lines, can point to more serious issues such as malnutrition, serious nail injury, or certain underlying conditions.
One of the underlying conditions that Beau's lines may indicate is hypothyroidism, a type of thyroid disease. Thyroid disease is caused by the malfunction of the thyroid, a butterfly-shaped gland in the neck that produces hormones that regulate heartbeat, breathing, and other functions. If left untreated, thyroid disease can lead to a dangerously slow or fast heartbeat, injuries that refuse to heal, or unrelenting pain.
Hypothyroidism, or an underactive thyroid, can cause thick, brittle nails with vertical ridges. In addition to nail changes, hypothyroidism can also cause dry skin and hair, weight gain or loss, fatigue, and feeling cold. If you notice these symptoms, it is important to consult a doctor or a dermatologist, who may be the first to notice signs of thyroid disease due to its impact on the skin, hair, and nails.
While vertical ridges are usually harmless, if they are accompanied by other symptoms such as colour changes, pain, or nail splitting, it may be a cause for concern. In such cases, it is recommended to consult a doctor or dermatologist, who can examine the nails and determine if further testing is required. Treatment for thyroid disease can often resolve related nail problems, and in the meantime, moisturizing the nails and keeping them trimmed can help manage the condition.

Horizontal nail ridges, called Beau's lines, can indicate a serious underlying condition
Horizontal nail ridges, known as Beau's lines, can indicate an underlying medical condition. These lines are horizontal ridges or dents in one or more fingernails or toenails. They are often a sign that an illness, injury, or skin condition interrupted your nail growth. While ridges in your nails are usually harmless, Beau's lines can suggest a serious condition.
Beau's lines are typically caused by an underlying illness or nail damage that occurred several weeks or months ago. Chronic conditions that require treatment can also cause them. Multiple Beau's lines on each nail may indicate that an illness or trauma occurred more than once. Thicker Beau's lines may suggest that an illness or trauma lasted for a more extended period.
Beau's lines can be a symptom of various health issues, including vitamin or mineral deficiencies, diabetes, malnutrition, and nail injuries. They can also be caused by certain medications, particularly chemotherapy drugs. In some cases, Beau's lines may be a sign of acute kidney disease. Therefore, it is important to consult a doctor or healthcare provider to determine the underlying cause and receive appropriate treatment.
Treating the underlying cause of Beau's lines is essential to promoting smooth nail growth. For example, if Beau's lines are caused by diabetes, successfully managing blood sugar levels may help reduce these horizontal nail ridges. Similarly, addressing vitamin or mineral deficiencies through dietary changes or supplements can help improve nail health. It is worth noting that Beau's lines grow out gradually after recovering from or treating the underlying cause, which typically takes about six months.

To improve the appearance of hard, dry nails, apply moisturiser to your nails and cuticles daily
Hard, dry nails with ridges are often a normal part of the ageing process. However, they can also be a sign of underlying health conditions, such as vitamin deficiencies, diabetes, heart and circulatory diseases, hypothyroidism, liver disease, chronic kidney disease, or rheumatology diseases. If you are concerned about the appearance of your nails, you should consult a doctor or dermatologist.
To improve the appearance of hard, dry nails, it is recommended to apply moisturiser to your nails and cuticles daily. Moisturising your nails will not only improve their appearance but also ensure the nail and surrounding skin stays healthy. You can use any type of hand cream or a cream specifically designed for nails and cuticles. Oils, such as olive, coconut, jojoba, sunflower, Brazil nut, or vitamin E oil, tend to absorb even better than creams.
When moisturising your nails, it is important to massage the product into your nails and cuticles for at least a minute. This will help to reduce peeling and brittleness, as well as stimulate blood circulation to encourage healthy nail growth. It is also beneficial to moisturise your nails immediately after water exposure and before bed. Additionally, you can use a humidifier during dry winter months to prevent your nails and skin from drying out.
To further improve the health and appearance of your nails, it is recommended to wear gloves when using harsh cleaning products or washing dishes, as these activities can contribute to dry nails. You should also be mindful of the nail products you use, as certain ingredients in nail polishes and removers, such as formaldehyde and acetone, can dry out your nails.
