Last Wednesday, I went for my routine haircut and highlighting for my hair. When I got there for my appointment, the woman that does my hair said that she wanted to try something different - without asking me first. She just colored my hair by putting this stuff directly onto my roots (I usually just get it highlighted - which I've been happy with doing). When she put that stuff on me, my head started burning really bad. She said that it should stop after a few minutes - it didn't. I told her that it was burning really bad and she kept asking me if it was getting better and it wasn't. She had me sit there with it on my head the full 40 minutes anyway. I was thinking that maybe my head was just sensitive or something. But later that night, my scalp felt kind of scabby. I thought that maybe she had just left some of that stuff in my hair, so I washed it again. Today, I have scabs all in my head - mostly on the top of my head, but it seems to be spreading quickly. It also seems to be kind of itchy - and it is hurting. I can feel all of these bumps on my head. What should I do? Has this ever happened to anyone else? I am seriously considering never having my hair color changed in any way ever again. I know it won't be this way. I may not go back to this person anymore. I'm not sure yet. I am just scared of what is happening to my head. I am worrying that my hair might start falling out. That scares me to death! What do you think I should do?
