I got a haircut over the weekend and my stylist accidentally cut herself with the scissors. She was bleeding and some of the blood got into my hair. I'm concerned that she might have HIV. She did end up covering the wound with a bandage (after I asked her to). I'm concerned that some of the blood might have dripped onto my scalp and I have dermatitis & psoriasis that will sometimes cause bleeding. If she does have HIV, what is the chance that I might have gotten infected this way? I'm not sure if I had open wounds on my scalp.... Also, while she was styling my hair, she scratched me a few times and I'm concerned that there could have been blood exposure where I got scratched. Do I have any cause for concern?
