Striped nails can have various causes, ranging from harmless cosmetic issues to underlying health conditions. While some stripe patterns may be completely benign, it’s important to understand the different reasons behind their appearance and when they might require further attention. Some of the most common causes of striped nails include both natural and medical factors,

In terms of natural causes, aging is a common one. As you get older, vertical ridges, also known as onychorrhexis, often appear on nails. These ridges are generally harmless and are a natural part of the aging process. Injury or trauma to the nail can also cause stripes or discoloration. If you’ve had a past injury to the nail, such as a hit or compression, temporary streaks or ridges may appear. Over time, these usually fade as the nail grows. Nutritional deficiencies are another factor. A lack of essential vitamins and minerals, such as biotin, zinc, or iron, can affect the health of your nails and contribute to the formation of streaks or ridges. Ensuring a balanced diet can help support healthy nail growth and appearance.

However, striped nails can also be a sign of certain medical conditions. Beau’s lines, for example, are horizontal ridges that can form on the nails due to severe illness, high fever, or malnutrition. These lines typically appear when the body undergoes significant stress, such as after an infection or surgery. In many cases, they grow out over time as the nail heals. Melanonychia, which involves dark vertical stripes on the nails, especially if they appear suddenly, can sometimes signal a condition that requires medical evaluation. In some cases,

melanonychia is associated with melanoma, a type of skin cancer, so it’s crucial to have sudden dark stripes checked by a healthcare provider. Fungal infections can also lead to streaks on the nails, often appearing as white, yellow, or dark streaks depending on the type of infection. Autoimmune disorders, like psoriasis, can also cause nail changes, such as ridges, discoloration, or other nail abnormalities.While most causes of striped nails are not serious, there are certain signs that should prompt a visit to the doctor. These include the appearance of dark stripes that were not there before, deep horizontal grooves, and changes accompanied by nail pain, brittleness, or peeling. If you notice any of these changes, it’s important to consult with a healthcare professional to rule out any underlying conditions and ensure proper nail health.
