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.
This is a great product. I give it 4 stars only because I wish it had more of a lasting scent and the price is crazy high! I love when my hair smells fresh and clean all day. This shampoo leaves my hair soft and manageable.
