I have been using Matrix shampoo for my colored hair, and I find it okay for my hair, because anyways I have to use conditioner and serum after shampooing my hair! However, lately when I went to a local salon, for trimming my layers, they first shampooed my hair and then trimmed them. The shampoo they used was nexus vita tress biotin shampoo, and I could feel the difference in the texture of my hair. I wanted to know from some hair expert, whether it would be a great product to use for treated hair. Moreover, do you think it alone would suffice the moisturizing requirement of my hair! I would be grateful to you for your valuable inputs!
