Nice but not worth the expense. [SEP] I ordered this "sample" kit so I could decide if it was good enough to buy the full size versions. I do like the No 0 to use before shampooing, my hair feels really nice, is shinier than it was, and smooth---really great. It goes kind of fast- takes a lot of the liquid  to make your hair damp. I probably won't purchase again for a while only because my budget won't allow! If the bottle was $15 instead of $30 I'd buy it regularly. (I am "worth it" but could easily use a couple bottles a month, crazy at that price!)
