A member asked:

Horizontal indented line in one nail only. could it be a beau line?

A doctor has provided 1 answer

Yes: yes this could be Beau's line. You may have had some injury to the nail, or sometimes we see these with other systemic illnesses. However one nail involvement would suggest trauma or injury to the nail. Human nail grows from the base at the cuticle, and that is where the injury probably occurred
