Nail Care :: What are Beau’s lines

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.

There are several reasons that humans get Beau’s lines.

It is believed that there is a temporary cessation of cell division in the nail matrix. This may be caused by an infection or problem in the nail fold, where the nail begins to form, or it may be caused by an injury to that area.

Some other reasons for these lines include: trauma, coronary occlusion, hypocalcaemia, skin disease and may be a sign of systemic disease.

It may also be caused by an illness of the body, such as diabetes, certain drugs, such as those used in chemotherapy or even malnutrition.

This condition of the nail was named by a French physician, Joseph Honor? Simon Beau (1806-1865), who first described it in 1846.
