Hi There....I experienced the same problem a few months ago and was going crazy with the constant itching on my scalp. This had never happened before so I was really puzzled. I did the same thing as you guys....I used the selsun blue shampoo let it soak for a while and then wash it off. It would stop the itching for a while and then off we go again. In frustration, I went to my old friend Google (lol) for help. It was with interest that I read an article that said that sometimes a deficiency in B vitamins can cause this. So you guessed it.....I bought some and started using immediately. Don't know exactly when it happened but it was gone in I would say in a couple of days. Try it you never know it might help you....
