Query: What happened?

I have to agree with miamiwoman - the new formula (pink bottle) leaves your hair with fly-aways and extremely dried out. It is NOWHERE near as good as the yellow shampoo. How disappointing, as this really was one of the best shampoos I ever used. It used to brighten my blonde hair after it would turn brassy from well water, it no longer does. My mom also enjoyed the shampoo prior to the new formula, and agrees the pink bottle is not as good. Very upsetting.
