There are many reasons why your fingernails might be chipping. Nails are made of a protein called keratin, which forms multiple tough layers. However, nails can become thin and weak, causing them to chip. This can be due to a variety of factors, including aging, vitamin deficiency, frequent exposure to water, and the use of harsh chemicals. In some cases, nail abnormalities may even be a sign of an underlying health condition, such as lung disease or anemia.

What You'll Learn

Vitamin deficiency
Fingernails are made up of a protein called keratin, which requires nutrients to produce. Nails are also part of the body's outer layer, which acts as a barrier between the outside world and the internal body. Therefore, they can be an indicator of internal health.
Vitamin and mineral deficiencies can commonly affect fingernails. For example, a vitamin B12 deficiency can cause nails to become bluish or grey-brown. A zinc deficiency can cause depressions across the fingernails, and a vitamin D deficiency is linked to soft nails. Iron deficiency can also cause nails to become brittle and chip easily. Spoon-shaped nails, or koilonychia, can be caused by an iron or vitamin C deficiency.
In addition to vitamin deficiencies, nail issues can also be caused by injury, overexposure to moisture, or certain lifestyle factors. For example, frequent hand-washing, the use of harsh chemicals, and manicures can weaken nails.
If you are experiencing nail issues, it is recommended to eat a well-balanced diet rich in fruits, vegetables, and lean proteins. You can also try taking supplements, but be sure to consult your doctor first.

Exposure to water
To prevent water exposure from damaging your nails, you can take several precautions. One simple solution is to wear gloves when doing tasks that involve water, such as washing dishes. Cotton-lined rubber gloves are recommended to protect your nails from water exposure while still allowing your hands to breathe.
Additionally, it is important to dry your hands and nails thoroughly after they have been exposed to water. Ensure that you dry your hands and nails gently without applying excessive force, as this can also damage your nails. Applying a moisturiser or nail oil after washing your hands can also help to replenish lost moisture and prevent your nails from drying out and becoming brittle. Look for hand creams that contain vitamin E, as these can help to keep your nails nourished and healthy.
If your nails are already damaged due to water exposure, you can take steps to repair and strengthen them. Consider using a nail conditioner or a product that stimulates nail growth, as these can help promote new nail growth and strengthen your nails, making them less prone to chipping and breaking. It is important to be consistent with these treatments, as it may take several weeks of regular use before you see improvements as your nails grow out.
Finally, if you suspect that your nails are chipping due to a vitamin deficiency, you may need to adjust your diet or take supplements. Nails are made of keratin, a protein that also occurs in the skin and hair, and a deficiency in certain vitamins and minerals can affect nail health. For example, a lack of biotin (vitamin B7) is associated with brittle nails that are prone to cracking and peeling. Consult with a healthcare professional if you are concerned about a potential vitamin deficiency, as they can provide guidance on any dietary changes or supplements that may be appropriate for you.

Aging
The changes in nail growth and appearance due to aging may be influenced by several factors. One factor is blood circulation problems, which can affect the delivery of nutrients to the nails. Additionally, extended exposure to UV rays over time can contribute to nail damage and thinning. These age-related changes can make nails more fragile and prone to chipping.
Older adults, especially women over 60, often experience brittle nails, which can be characterized by splitting, peeling, or visible breakage. Nails may also become more fragile due to a decrease in hormone production associated with aging. For example, an underactive thyroid can lead to hormone imbalances and contribute to brittle nails.
While aging is a common cause of nail chipping, it is important to note that other factors can also contribute to this issue. For example, nutritional deficiencies, such as low levels of iron, protein, biotin, calcium, fatty acids, and vitamin B, can weaken nails and make them more prone to chipping. Additionally, lifestyle factors such as repeatedly washing hands or exposure to harsh chemicals can dry out nails and make them more fragile.
To mitigate the effects of aging on nail health, it is recommended to keep nails moisturized, especially after washing hands or doing chores that involve water. Using hand cream with vitamin E can help replenish lost moisture. Wearing gloves during household chores and limiting the use of alcohol-based sanitizers can also help prevent nail dryness and chipping. Keeping nails trimmed and filed can also reduce the likelihood of snagging and breakage.

Fungal infections
Fingernail chipping can be caused by fungal infections, also known as onychomycosis. This occurs when yeasts or molds enter your nails, causing an infection that makes them more susceptible to cracking or breaking. While this is more common in toenails than fingernails, it can be a source of concern for individuals with frequent fingernail chipping.
Additionally, consider using nail care products that are labeled "hypoallergenic," as they typically contain milder or natural chemical agents that are less likely to irritate your nails. It is also beneficial to incorporate a rich moisturizer or nail oil into your nail care routine to prevent your nails from drying out.
If you suspect that your fingernail chipping is due to a fungal infection, it is advisable to consult a dermatologist or a healthcare professional for a proper diagnosis and treatment plan. They may recommend specific antifungal treatments or provide guidance on maintaining healthy nails to prevent further chipping.
While fungal infections are a potential cause of fingernail chipping, it is important to note that there are other factors that can contribute to this issue, such as vitamin deficiencies, frequent exposure to water, and the use of harsh chemicals on the nails.

Underlying health conditions
Fingernails are made up of a protein called keratin, which also occurs in the skin and hair. Nails have multiple tough layers that can peel or split, causing them to appear thin and weak. The medical term for this condition is onychoschizia. While nail abnormalities are usually caused by external factors, they can sometimes be a result of underlying health conditions.
Vitamin deficiencies are a common cause of nail chipping. For example, a lack of biotin (vitamin B7) or niacin (vitamin B3) can lead to brittle nails that crack, chip, or peel easily. Iron deficiency is another common cause of nail abnormalities, and can be treated by eating more iron-rich foods or taking iron supplements.
In some cases, nail chipping may be a sign of a more serious health condition. For example, according to the American Lung Association, peeling nails can be a symptom of lung disease. Anemia, psoriasis, and thyroid problems are other medical conditions that can affect nail health.
If you are experiencing nail chipping and are unable to attribute it to an external or nutritional cause, it is recommended to consult a doctor, especially if the nail is painful or bleeding.
