They are called longitudinal ridges
Vertical lines on your nails are called longitudinal ridges. They are usually harmless and are often a sign of aging. However, they can sometimes be a sign of an underlying medical issue. Vertical ridges are usually a cosmetic issue, whereas horizontal ridges are often linked to more serious health issues, such as severe infections, diabetes, malnutrition, or nutritional deficiencies.
Longitudinal ridges are a common occurrence, especially with age, and are typically nothing to worry about. They are one of the most common causes of tiny vertical nail ridges (onychorrhexis), which extend from the bottom of the nail to the tip. Onychorrhexis mainly causes vertical ridges and splitting of the nails.
Nails may hold subtle clues to your overall health. While vertical ridges are usually benign, deeper horizontal ridges can point to issues like malnutrition, serious nail injury, or Beau's lines. Beau's lines are a separate condition from onychorrhexis and are often linked to more severe health issues.
Ridges in your nails can be a sign of a health condition or a previous injury to your nail. In some cases, they are harmless. If you are concerned about the appearance of ridges on your nails, you can connect to a dermatologist in your area for further advice and guidance.
