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.
Fantastic shampoo! Worth every penny. My only criticism, it arrives in a box, with corregated card inside and cellophane on the outside....well over packaged. The bottle is plastic after all, not glass. So why all the layers of packaging? 🥺
