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.
100% knock off. I was obsessed with the authentic version but ran out and went with cheap shampoos. Finally caved in and went back to this one but first time buying outside of a salon. The quality was horrible in the sense that one dime sized squirt would clean my hair well, now I have to fill my entire palm with shampoo to actually get a deep clean.
