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.
Absolutely love this product, it works wonders for my hair. However, it arrived with the lid off and some of the product had leaked into the plastic shipping bag, kind of a bummer since the bottle is small to begin with.
