Dry and itchy scalp treatments?

I used to use the L'Anza healing remedy scalp treatment and it worked WONDERS for my dandruff. I stocked up on extra as well when they started phasing out the line and changing all their formulas and packaging. Now that I've nearly run out of it, I was curious if anyone knows of any dupes? I even got special shampoo from the derm and it did not work nearly as well as the L'Anza treatment that no longer exists :(
