At this site and on Amazon, CC has a rating 3.5, with people complaining that it's too harsh compared to regular sulfate shampoos. Meanwhile, the Suave clarifying shampoo has a 5 star rating here and on Amazon. It's terrific. I've used it for years.
Plus $12 for 8 oz.s of CC is far too steep (a consistent complaint from a lot of people about all
Kinky Curly products). Meanwhile, you can get that 5 star 22.5 oz.s of Suave for $2.29, and it practically lasts forever
... Oh, and Suave will also remove hard water buildup.
