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 have another product from this brand- body scrub , which I love and that was the reason I bought the shampoo. But this one disappointed me ! Far too expensive for its performance. Doesn’t actually do much more than a similar but much cheaper shampoo! Won’t buy it again!
