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.
