To calculate the overall star rating and percentage breakdown by star, we don’t 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 do not like the color shampoo at all. It makes my hair feel like sandpaper. I was very disappointed when I started using it because I love the volumizing shampoo and thought this one would be great too. It was extremely expensive and I really don't like it.
