Discolored fingernails?!
Question:
Discolored fingernails?
for as long as i can remember, i have had dark (almost black) lines on both my thumbs, my index and middle finger (right hand). they aren't so noticable they are distracting, but manacurists and friends often question it. a friend recently told me it is a deficiency, but not sure of what. is this true? and if so, what am i lacking?
