What are Beau's lines associated with?

Beau's lines refer specifically to visible depressions that run horizontally across the width of the natural nail plate. These lines are typically indicative of temporary interruptions in nail growth, which can be caused by various factors such as physical trauma, severe illness, malnutrition, or other health-related issues that affect the body's ability to grow nails uniformly.

Understanding Beau's lines is important for nail technicians because they can offer insights into a client's overall health status and any previous conditions that might have impacted nail growth. This knowledge allows for better assessments and more tailored care in nail treatments. The other options describe different nail conditions that are unrelated to the formation of Beau's lines, emphasizing that each condition has distinct characteristics and implications for nail health.
