To calculate the overall star rating and percentage breakdown by star, we do not 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 great in between salon visits. Every few weeks I touch up my brown and gray roots with this. I tried the other Clairol root touch up, Ash Blonde 9A, and would leave it on for 45 minutes. It would not lighten sufficiently. This kit is left on for about 10 or 15 minutes and it lightens the roots and blends beautifully.
Seller must have sent an old and or expired product. Couldn’t use either box. The mixture was chunky and it it turned an awful mustard yellow/brown color in the mixing cup. Would never put this on my hair and will attempt to return. Not recommended.
