Peeling nails can be caused by external trauma to the nail
Peeling nails can be unsightly and are often caused by external trauma to the nail. This can be the result of physical trauma, such as slamming your finger in a door, or using your nail as a tool, pressing into the nail too firmly, or removing acrylic nail polish. Nails are made of a protein called keratin, which forms multiple tough layers that can peel. This trauma can cause the layers to split and peel, leaving the nails looking thin and feeling weak and sensitive.
External trauma to the nail can also be caused by environmental factors, such as exposure to water and moisture. For example, repeatedly getting the nails wet and then drying them can cause peeling. Additionally, soaking the hands in water for long periods while performing household chores can make the nails soft and prone to peeling.
Excessive handwashing can also lead to peeling nails. This is because the soap absorbs into the sensitive layers of the skin, causing irritation and peeling. Using irritating paper towels and hot water can further exacerbate this issue.
Artificial nails can also be a culprit. Forcing off the nail coating can damage the nail and lead to peeling. This can scar the nail beds, resulting in thin and fragile nails.
Finally, external trauma can also include exposure to certain chemicals. For example, some of the chemicals in moisturizers, soaps, and other beauty products can cause skin irritation that results in peeling nails. This is known as contact dermatitis.

Internal causes, such as vitamin or iron deficiency, can also cause peeling nails
While nail issues often occur due to injury or overexposure to moisture, they can sometimes indicate vitamin or iron deficiency. Dr. Sara Norris, a naturopathic doctor, explains that "brittle, weak, and peeling nails are the most common concerns I see in my practice, and these symptoms are more often the result of a poor diet than of systemic disease."
One of the most common nail problems is rough, splitting nails that may also crack easily. Officially called onychoschizia, brittle nails are usually caused by repeated wetting and drying of fingernails. However, in some cases, they might indicate an iron deficiency or hypothyroidism. Similarly, spoon nails, where the nail appears concave either horizontally or vertically, are typically associated with anemia or an iron deficiency.
If both your fingernails and toenails are peeling, it likely indicates an internal cause, such as a vitamin or iron deficiency. Vitamin B12 deficiency, for instance, can cause nail discoloration. However, it's important to note that nail issues are rarely a cause for concern and are usually not a medical emergency.
If you suspect that your peeling nails are due to an iron deficiency, consider evaluating your diet and focusing on food sources rich in iron. However, consult a doctor to determine if supplements are recommended for your specific case. Additionally, if you observe spoon nails, it is advisable to see a doctor as this condition may be associated with other inflammatory skin diseases or autoimmune disorders.

Onycholysis, or nail separation, is when a nail separates from the skin it rests on
Peeling nails can occur due to various external factors, such as trauma to the nail, harsh weather, or moisture exposure. In rare cases, peeling nails can indicate an underlying internal condition.
One such condition is onycholysis, or nail separation, where the nail separates from the nail bed—the skin on which the nail rests. This condition can be caused by several factors and usually affects only one nail. Onycholysis is generally painless and lasts for several months or over a year. It is more common in women and pregnant individuals and can result from certain medical conditions, medications, or nail product usage.
Causes of Onycholysis
Onycholysis can occur due to various reasons, including:
- Trauma or Injury: Even slight or repetitive trauma, such as daily tapping of long fingernails on a keyboard, can cause nail separation.
- Fungal Infections: Fungi can enter through cracks or cuts in the fingers or toes, causing the nail to thicken and turn yellow, with possible white spots and streaks.
- Medications: Certain medications, such as psoralen, tetracycline, fluoroquinolone, and oral retinoids, can cause onycholysis.
- Medical Conditions: Conditions like psoriasis, hyperthyroidism, eczema, lichen planus, thyroid disease, and some forms of bacterial or fungal infections, can lead to nail separation.
- Nail Products: The use of harsh nail products, such as nail polish remover and artificial nails, can contribute to onycholysis.
Treatment
The treatment for onycholysis depends on the underlying cause. In some cases, cutting away the separated nail as it grows out may be sufficient. For fungal infections, antifungal medications or stopping the use of certain nail products may be recommended. If the onycholysis is due to a medical condition or medication, treating the underlying condition or substituting the medication may be necessary.

Peeling nails can be the result of too little or too much moisture
Peeling nails are usually not a cause for concern and can be treated at home. However, if the nails are also painful or bleeding, it is recommended to seek medical advice. Peeling nails can result from various causes, one of which is moisture imbalance.
Nails can be damaged by too little or too much moisture. When nails are repeatedly wet and dried, they can become dry and brittle, making them more prone to peeling. This can be prevented by thoroughly drying the hands and nails after washing them and regularly applying hand cream or nail oil to replenish lost moisture. Additionally, wearing gloves while doing chores that involve water can help protect the nails.
On the other hand, excessive moisture can also lead to nail peeling. Prolonged exposure to water, such as during household chores, can cause the nails to swell and become soft, making them susceptible to damage and peeling. To prevent this, it is recommended to wear cotton-lined rubber gloves while performing tasks that involve prolonged contact with water.
Other causes of nail peeling include external trauma to the nail, such as picking at nail polish, biting nails, or using them as tools. In some cases, nail peeling may indicate an underlying condition, such as vitamin or iron deficiency, or a systemic condition. If you suspect your nail peeling is due to a deficiency, increasing your daily intake of certain vitamins or minerals or taking supplements may help. However, it is always advisable to consult a doctor or dermatologist for guidance and to determine the underlying cause.

Underlying health conditions, such as lung disease or an underactive thyroid, can cause peeling nails
Peeling nails are usually caused by external factors, such as trauma to the nail, vitamin deficiencies, or overexposure to moisture. However, in rare cases, they can indicate an underlying health condition, such as lung disease or an underactive thyroid.
Lung disease can present itself in various ways, and nail changes are one of the possible symptoms. According to the American Lung Association, the symptoms of lung disease may include nail abnormalities. Therefore, if you notice your nails peeling and suspect it could be related to lung health, it is important to consult a doctor for further evaluation and an accurate diagnosis.
An underactive thyroid, also known as hypothyroidism, is another potential cause of peeling nails. The thyroid gland is responsible for producing hormones that regulate various bodily functions. When the thyroid is underactive, it does not produce enough of these hormones, which can lead to a range of symptoms, including brittle and peeling nails. Treatment for an underactive thyroid typically involves synthetic thyroid hormones, which help restore proper hormone levels in the body.
While nail issues are often related to external factors, it is important to consider underlying health conditions if the problem persists or is accompanied by other symptoms. For example, if you notice horizontal lines on your nails or other changes in texture or colour, it may be a sign of vitamin B12 deficiency or inflammatory skin diseases like psoriasis. Therefore, if you are concerned about persistent or unusual nail issues, it is advisable to consult a healthcare professional for proper diagnosis and treatment.
In most cases, nail issues can be treated at home with proper care and nutrition. Eating a variety of whole foods, including fruits, vegetables, and whole grains, can provide the necessary vitamins, minerals, and nutrients for nail health. Additionally, gentle nail care practices, such as filing nails with a nail file and avoiding forceful removal of nail coatings, can help prevent nail damage and peeling.
