What You'll Learn
Vertical lines on nails are usually harmless
Horizontal lines, on the other hand, can point to issues like malnutrition, serious nail injury, or Beau's lines. Beau's lines can be caused by something interrupting nail growth, such as chemotherapy, damage from artificial nails or gel manicures, injury to the nail, peripheral vascular disease (PAD), or a severe illness with a high fever, such as COVID-19, measles, or pneumonia.
While vertical lines on nails are typically not a cause for concern, if you are concerned about the appearance of your nails or notice any other changes, it is always best to consult with a healthcare professional or dermatologist for further evaluation.
