What Causes White Lines on Nails?

White Lines on Nails

White lines or streaks on nails, also known as “leukonychia,” can have various causes, ranging from minor to more serious underlying health conditions. Here are some potential reasons for white lines on nails:

  • Trauma or Injury: The most common cause of white lines on nails is minor trauma or injury to the nail matrix, the area where the nail begins to grow. This trauma can result from activities such as bumping your nails, slamming them in a door, or excessive use of nail tools.
  • Nutritional Deficiencies: Deficiencies in certain vitamins and minerals, such as zinc, iron, calcium, and protein, can lead to changes in nail health, including the development of white lines.
  • Allergic Reactions: Allergic reactions to nail polish, nail hardeners, or other nail care products can cause white lines or streaks on nails.
  • Fungal Infections: Fungal infections, such as onychomycosis, can affect the appearance of nails, causing discoloration, white spots, or lines.
  • Systemic Diseases: Certain systemic diseases or health conditions, such as psoriasis, eczema, liver disease, kidney disease, or thyroid disorders, may manifest as changes in nail health, including the development of white lines.
  • Medications: Some medications or medical treatments can cause changes in nail health, including the appearance of white lines or streaks on nails.
  • Chemical Exposure: Exposure to chemicals or toxins, such as heavy metals, can affect nail health and lead to the development of white lines or streaks.
  • Genetic Factors: In some cases, white lines on nails may be inherited and not necessarily indicative of an underlying health problem.

If you notice persistent or recurring white lines on your nails, it’s essential to consult with a healthcare professional or dermatologist for proper evaluation and diagnosis. They can help determine the underlying cause and recommend appropriate treatment or management options.
