I have a ton of hair but it's very thin and fine so I was looking for a shampoo that would give it some boost and was sulfate free because of a treatment ii have on my hair. I was skeptical about trying this one mainly because of the scent. I am not a fan of Rosemary, but this actually has a beautiful scent to it that isn't harsh or overpowering. My hair is super soft and full looking after just one wash! It is pretty expensive as far as shampoo goes though at $10 a bottle.
