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 use it since a month every week, and yeah it is very good, but maybe for the price I expected more. It is good and leaves the hair light and soft, but it is not very a spectacular effect, especially in a long term treatment.
This absolutely is not the same product as you get in a salon. It is a much thinner consistency and does not leave your hair nearly as soft as the real product. I only bought it once and I will never buy it again from Amazon.
