I can't believe this cost even more than the shampoo ! At Sephora, it retails for $40 and you get 6.7 oz.

You don't need a lot of product, but this is a very costly investment. Although I am thinking of making the switch from drug store brands. After using this for a week, I would definitely say that my hair is stronger and softer, while also being healthy. I also notice less fall outs in the shower.
