About a month ago I had cornbraids put into put into my hair. Shame on me I did not go to my original braiders. I will never to that again. One of my braids ended up being too tight and I had to take it out the same week. At the root there were a few bumps. They are now gone but there the spot is dark. It looks like a bruise. Does anyone know what seems to have happened to my scalp? Did cells die or something? The spot is small and near my hair line. I still have my brids so I really can't tell if a hair is missing from that spot.The spot is smooth but as I said it looks like a bruise. Has anyone experience this? Can you tell me what I should do about it. Thank you
