Recently I was in the store and I noticed a brand called Renpure. It claims to be free of parabens, gluten, and pretty much everything nasty for your hair (supposedly). I was intrigued by their Rosemary Mint cleansing conditioner after hearing so many people using WEN or baking soda/vinegar rinses instead of shampooing. I suppose my question is what do you think of it? Are these at all effective, and what especially in this product makes it effective to cleanse and condition hair without making it greasy and dirty.
