I received a sample packet of this shampoo and the accompanying treatment in my Birchbox a few months ago. I dyed my hair last week so I pulled out the sample to test. Terrible. The shampoo had a very liquid, runny consistency and it didn't lather well. After using it, my scalp didn't really feel clean and I noticed that my hair got greasier far quicker than usual. I won't bother writing a review for the treatment, but I also didn't enjoy it. It didn't have a nice, texture and didn't give my hair very much slip or make it feel any smoother or look shinier. I mean, after one use I can't say much about how these products have helped preserve my color. But overall, I do not believe they are not worth the exorbitant price tag.
