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 like this product. After a hysterectomy my proccessed hair was breaking along my hairline.. Along with the shampoo and the leave in and an occasional extreme bleach recovery system use, also by Redken.(once a week) my hair has made a real comeback.
I’ve only been using this product for about three weeks, I felt the transformation within the first use. I am 100% committed and continue to use the shampoo conditioner and deep conditioning product it is great so far you must try it
