What are Beau's lines?

Beau's lines are specifically identified as visible depressions running across the width of the nail plate. These lines typically occur due to a temporary disruption in nail growth, which can be the result of various factors, such as illness, nutritional deficiencies, or severe trauma. The formation of these grooves indicates a period where the nail matrix was affected, causing the nail to produce a ridged surface as it grows.

The presence of Beau's lines can serve as an important visual cue for technicians and can help in assessing the overall health and conditions of a client’s nails. By recognizing these characteristics, nail technicians can better identify potential underlying health issues that may need to be addressed or monitored.
