I'm really happy with this. I have shoulder length hair that is fine in texture, but abundant. The entire line smells absolutely amazing, but light enough to not irritate. Initially, I was going to just buy the full size clarifying shampoo, but this wasn't a whole lot more with my points and includes a full sized leave in conditioner, so I figured why not try the other stuff! The clarifying shampoo is fantastic as it removes buildup and moisturizes (it has oils in it that somehow don't weigh hair down). When I first shampooed with this, I felt the oils in it and worried that my hair would be a greasy, gross mess, but it left me with soft, clean hair. I really can't see using it more than once a week, though- it's crazy that they suggest that you can use it daily! The mask leaves my hair feeling soft, smooth and not at all weighed down. Still, a mask from Earth Science that I use works a lot better, at a fraction of the cost, so I probably won't purchase a full size of this. Both the mask and the shampoo are super concentrated, so a little goes a very long way. The leave in conditioner is really nice and light, it detangles my hair and leaves it smelling heavenly! I don't know that it's worth the retail price of $32, though. I have not tried the repair oil. If you have the extra money, this kit is well worth trying out.
