Beau’s Lines

Beau’s lines refer to a condition in which horizontal depressions or grooves occur across the nails. They are named after the French physician Joseph Honoré Simon Beau, who first described this phenomenon in the mid-19th century. Beau’s lines can occur on both toenails and fingernails and are often a sign of an underlying health issue or a disruption in the normal growth and development of the nails. These lines can be caused by various factors such as nutritional deficiencies, infections, trauma to the nail, systemic diseases, or even as a side effect of certain medications. The severity and appearance of Beau’s lines can vary depending on the underlying cause and individual circumstances.
