Causes of Striped Nails
Striped nails can result from various factors, ranging from harmless to health-related issues. Here are some possible causes:
Natural and Harmless Causes
Aging: As we age, vertical ridges (onychorrhexis) become more common.
Injury or Trauma: Past nail injuries can lead to temporary discoloration or ridges.
Nutritional Deficiencies: Lacking vitamins like biotin, zinc, or iron can cause nail issues.
Medical Conditions
Beau’s Lines: Horizontal ridges may appear due to illness, fever, or malnutrition.
Melanonychia: Dark stripes, especially when sudden, may need a doctor’s attention.
Fungal Infections: White, yellow, or dark streaks may indicate fungal issues.
Autoimmune Disorders: Conditions like psoriasis can cause ridges or discoloration.
