Which of the following is a common cause of onychorrhexis (brittle nails)?

  1. AImproper removal of artificial nail enhancements.
  2. BOverexposure to UV light during gel application.
  3. CSystemic fungal infection of the nail plate.
  4. DMoisture retention under nail polish.
Show answer & explanation

Correct answer: A. Improper removal of artificial nail enhancements.

Onychorrhexis, or brittle nails, can be caused by various factors including chemical exposure, nutritional deficiencies, and trauma. Improper removal of artificial nail enhancements often involves tearing or prying, which can severely damage the nail plate, leading to brittleness and splitting.

Why the other options are wrong

  • B. Overexposure to UV light can lead to skin damage or nail plate discoloration, but not typically onychorrhexis directly.
  • C. Systemic fungal infections typically cause onychomycosis (thickening, discoloration, crumbling), not primarily onychorrhexis.
  • D. Moisture retention under nail polish can contribute to bacterial or fungal growth, not primarily onychorrhexis.

Onychorrhexis

A condition characterized by abnormally brittle nails with lengthwise ridges, often splitting at the free edge.

  • Also known as brittle nails.
  • Can be caused by trauma, chemical exposure, or systemic conditions.
  • Often associated with improper nail care practices.

Memory trick: Nail conditions are often a sign of underlying issues.
