I got a sample of this in my box a few months ago. I would not recommend this product to anyone with dry hair. My hair is dyed but it is also naturally curly. After using gentle products meant for curly hair for several weeks, this was very drying, it smells a bit like chemicals - furniture polish? and the color on my hair looks no better (and no worse, honestly) than it did before. I color my hair red and it looked like a lot of it bled out during the rinse. Also, this stuff lathered like CRAZY on me - I thought it was no lather? It may work fine on those of you who lighten your hair. I have a feeling this would also work well as a clarifying shampoo if you're into that kind of thing, or if you use a lot of product.
I followed up with the recommended conditioner, which seemed really thin and slippery. After I towel-dryed my hair, I applied some leave-in conditioner to get it hydrated again. Honestly, I haven't felt this turns off by a shampoo since being forced to use White Rain at my mom's house when I forgot my own.
