I have the smoothie and I love it I also have the deep treatment masque which is pretty good and the shampoo which isnt a deep enough cleanse for me when I do chose to shampoo.

Don't let the cashier scare you off of trying something. Everyone's hair is different and thus will react differently to products, if you don't try it out for yourself you will never know if you are missing out on something your hair loves. I say be brave and try it, at least that way you will know for sure and can make your own conclusions.
