What does a finger nail narrow stripe mean

Customer Question

My 16 year old daughter has a weird dark narrow stripe on her fingernail.

Expert:  Pauline replied 10 years ago.

Are you able to upload a photo of the nail?

How wide is the stripe? Is it running horizontal or vertical across the nail?

What is the color?

Is it the nail itself or the skin under neath the nail?

Has she any history of trauma to the hand in last 6 months?

Does she take any medication?
