Questions about fingernails - black lines
Hi,
I can't find any answers on a google search, and plenty of people have asked. What is the cause of short, hair-like, verticle black lines in the nail beds? Would be located on the thumbs and small pinkie toes, for some reasons. Not due to nail trauma. Is this heavy metal? I have noticed that they have been improved, so far, with MMS. Any input? Thanks! |
