My hair were extremely damaged on one side and I tried this Shampoo and Conditionner, switched to Redken Extreme and then came back to these. My hair health has improved, but, it's the first time I use a product that gives me scalp acne. It's not extreme, but I do notice one or two new pimples everytime I wash them. I hate it, I'm probably going to try Redken soothing balance shampoo. If that doesn't work, I'll be saddly switching brands. I do not know if it's the combination of the shampoo and the conditionner or only one of them, but I wrote the same review for the shampoo product.
