I have used this shampoo for a couple weeks now along with the coordinating conditioner and am very happy with the results. My hair is clean, soft, and manageable. I like to alternate this system with the Griffin Remedy Volumizing Shampoo and Conditioner, which works for me. I highly recommend the Antiaging Shampoo and Conditioner. It's good for your hair and is very cost effective.
