I purchased this shampoo after reading about it in the science-y hair blog, stating that the c14-16 olefin sulfonate cleansing agent in this shampoo might help remove polyquats and styling polymers better than the usual sulfate clarifying shampoos. My hair is 2C, fine, low/ medium porosity, and we have soft water where I live. Lately my clarifying shampoos haven't been quite cutting it, and I wanted to see if this cleansing agent might in fact help.
Well let me tell you, this is breaking out the big guns. It got out whatever my regular clarifying shampoo wasn't touching. It's supposed to also be good on silicone build up. Non water soluble polyquats, though they are conditioning, can be lurking in all kinds of products, so if polyquat or silicone build up is an issue for you, and you suspect your regular clarifying shampoo isn't doing its job, you might want to try this shampoo. It is quite drying, so I consider this an emergency use, once in a while type of a product only. No idea why they call this moisturizing, I consider this a heavy duty clarifier. I do have soft water in my house & still this was very stripping. I paid $8.99 for this at Target.
