question: I dyed my hair last week, and I got some dye on my fingers. The next day I discover a couple small black dot close to my finger tips. Over the next couple of days, my finger is numb and I m unable to feel with that finger. It seems like those dots are on four of my fingers on my right hand and one on my left hand. Could it be the dye that cause it? If not, what could be the cause? How could I cleanse it?
