What You'll Learn

Trauma to the nail
Peeling nails can also be caused by internal factors such as vitamin deficiencies, typically an iron deficiency. However, it is important to note that peeling nails are usually not a sign of a major medical issue. As we get older, nail changes are common.
If you are experiencing peeling nails, it is a good idea to compare your toenails and fingernails. If your fingernails are peeling but your toenails are not, this signals an external cause. On the other hand, if both your fingernails and toenails are peeling, this indicates an internal cause.
It is also worth noting that it takes about 6 months for a fingernail to grow to its full length. This means that nail abnormalities can be the result of something that occurred months earlier.

Underlying health condition
Peeling nails are usually not a sign of a major medical issue, but they can sometimes indicate an underlying health condition. If both your fingernails and toenails are peeling, this could signal an internal cause, such as a vitamin deficiency, typically an iron deficiency.
Peeling nails can also be caused by external factors, such as trauma or damage to the nail itself, or prolonged exposure to water. However, if you can't attribute your peeling nails to an external or internal cause, comparing your toenails and fingernails can help determine the difference. If only your fingernails are peeling, this signals an external cause.
While nail changes are common as we age, it's important to be aware that peeling nails can, in rare cases, indicate a systemic condition or a pathologic process occurring inside the body. If you are concerned about your nail health, it is always best to consult a healthcare professional.

Peeling nails are usually not a sign of a major medical issue, but they can indicate a vitamin deficiency, typically an iron deficiency. If both your fingernails and toenails are peeling, this signals an internal cause. If your fingernails are peeling but your toenails aren't, this suggests an external cause, such as trauma or damage to the nail itself. Soaking your hands in hot water while doing the dishes or engaging in any other prolonged water exposure can dry out the nails and cause them to peel.
Nails consist of layers of a protective fibrous protein called keratin, which also occurs in skin and hair. Keratin makes nails strong, but external trauma or an underlying health condition can cause thin layers of the nail to peel away. When this occurs, it can leave the nails looking thin. They may also feel sensitive or uncomfortable. Causes of peeling nails include exposure to chemicals and wearing acrylic nails.
