Beau's lines
/laɪnz/
1. [noun] beau's lines are deep grooved lines that run from side to side on the fingernail or the toenail. They may look like indentations or ridges in the nail plate. They usually develop when nail plate growth, which begins in the nail matrix (located under the cuticle), is temporarily disrupted
Frequently Asked Questions
How might regular foot inspections reveal the presence of Beau's lines on toenails during daily care?
During routine foot care, you may notice horizontal grooves running across the toenail. These Beau's lines appear as noticeable indentations or ridges and signal a period when nail matrix activity was temporarily interrupted, distinguishing them from normal nail textures.
Why can Beau's lines on toenails be confused with other nail irregularities during self-examination?
Beau's lines sometimes resemble indentations caused by minor injuries or simple wear. However, their aligned, deep grooves indicate a disruption in the nail's growth phase, making them distinct from common, non-specific nail surface irregularities.
