Suggest Treatment For Itching In Head

Hello,

My name is Garry and I had an accident in 2003. I wrecked a motorcycle and went head-on into an oak tree. I am doing pretty good now-a-days, but I have had the worst ichy head every since the wreck.I have been to my family doctor and tried the meds he gave me. No good. He recomended that I went to a specialist. I did. She kept talking about my hair was to dry. The only releif I can get is hot-hot water. After I get releif, I wash my hair with Dail gold bar soap. That is the only thing that will help but it only works for a while. It works until my hair get oily again. As long as I keep the oil out and my hair clean it's not as bad. At the end of the day it's gone crazy again. When it starts iching, I can spray down with rubbing alcohol and this does give me releaf. What can I do. I have bumps that come up on my head and I also get the same ich in my groin. Hot water is all I can get releif from also. Once again when I scratch or rub, it's sightly oily. HELP !!!!!!
