This is the most drying, horrible shampoo and conditioner I've ever used [SEP] I have gray hair and I'd like it to look more silver. From the product information I thought this shampoo/conditioner combo would help. Boy, oh, boy was that a mistake. The stuff is horrible. My hair has never been so dry. It feels like straw and the ends are breaking off after using it as directed. My hair color is brassier and uglier than ever. I won't use this shampoo or conditioner on my hair again.  Can I return the stuff?
