Query: buy it from a salon

This is a very good product in principle, I really like using it - it makes fine colored hair look and feel fantastic. However, the stuff I got from Amazon seems to be inferior quality than the same shampoo that I used to get in the salon. Hair has a distinct greasy afterfeel. Even though it's a good deal on Amazon, I won't buy it again from here.
