Body On Tap Shampoo for colour treated hair

I have recently used Body On Tap shampoo for coloured hair, expecting it to give my hair some volume as well as protect my colour treated hair. I was very disappointed to find that it dried my hair out to the point where my hair felt like grass after each wash, even after after applying a lot of conditioner to my midsection to my ends. This is one of those products I would never in my life repurchase, I still have a quarter bottle left, but would definitely not finish it. My hair has never been that damaged and I'm very disappointed in this product.
