I have used the gentle shampoo/conditioner, and I didn't like it very much. It made my hair really dry. I have also used the reds shampoo/conditioner, and it just made my hair kinda orangey, not redder. I don't know, but I guess it just depends on your hair type. I've seen better salon products at a cheaper price. Oh yeah, I also have the tonic detangler/leave-in conditioner.....it's alright. I still use it once in a while. I don't think I'll ever buy anymore shampoo/conditioners, though.
