Some of them are and some of them aren`t. Was it the salon that advised the Kerastase and did they sell it themselves? They obviously want to get as much revenue as possible, rather than pointing you towards something from the high street.
I personally think medium range products are good. I like Paul Mitchel. It`s dear, but not that dear. You should just try lots of different products until you find one that works. Some cheaper brands have silicone in them (for shine) and that weighs down fine hair.
