Splitting Nails (Onychoschizia)

Understanding the causes, symptoms, and treatment of nails that split, peel, or separate in layers.

What are Splitting Nails?

Do your nails peel or split into thin layers? Learn what causes nail splitting and how to restore nail strength and health.
Splitting nails, also known as onychoschizia, occur when the nail plate separates into horizontal or vertical layers. This condition is often caused by repeated exposure to water, harsh chemicals, trauma, or nutritional deficiencies. Identifying the cause and improving nail care habits can prevent further damage and promote stronger nail growth.

Common Symptoms

  • Nails splitting or peeling at the tips or along the sides
  • Thin, brittle, or fragile nail texture
  • Uneven nail surface or ragged edges
  • Increased breakage during routine activities
  • Sensitivity or mild pain around the affected nail

When to see a dermatologist

  • Splitting occurs frequently or affects multiple nails
  • Nails become painful, discolored, or deformed
  • Accompanied by signs of infection or inflammation
  • Symptoms persist despite home care and moisturizing
  • You suspect an underlying medical condition or deficiency

Early detection is important for managing the condition and preventing further complications.
