Sorry, not much help here with that shampoo. Lately Tea Tree Oil has become a pretty popular thing. I know that it help heal sores and prevent infection.
Have you tried any other kinds of Shampoo for dry scalp? Just a word from the wise (ya right!
), most of the dry scalp shampoos have chemicals in them and they will strip out a perm or hair color quite well! My Mom once got a perm and happened to run out of her regular shampoo, so she used my Dad's Denorex for dry scalp...and her perm was completely gone! So, I'd be a little careful when it comes to certain kinds of shampoo since I know you just recently colored your hair red.
Hope that helps a bit!
