To calculate the overall star rating and percentage breakdown by star, we do not use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
I bought this cos Aveeno is a trusted product name, and was hoping that the shampoo would turn out nicely too. It lathered nicely - not too much, neither was it too little, and the scent was just nice too and not overpowering. I currently alternating this with another shampoo, and would get it again.
