Beau’s lines are deep grooved lines that run from side to side on the fingernail. They may look like indentations or ridges in the nail plate. This condition of the nail was named by a French physician Joseph Honoré Simon Beau (1806–1865) who first described it in 1846.Beau’s lines are horizontal going across the nail and should not be confused with vertical ridges going from the bottom (cuticle) of the nail out to the fingertip.
