I love this shampoo and conditioner. It's not an all-natural product, which I usually go for, but it is quite gentle and for some reason it works wonders on my curly, drier hair, leaving it silky, with the frizz calmed down, and manageable to style. I don't know what it is, but it works super for me. My favorite thing about the duo is the scent, which is a sophisticated and adult scent that's elegant and subtle. My one tip would be, that I buy two shampoos to one conditioner, because I seem to go through the shampoo much more quickly. I have a lot of long hair, so maybe for a person with short or fine hair, this will not be an issue.
