I have tried a couple different redken shampoos.
I did like this one better than the color treated redken shampoo.
This shampoo was more hydrating than the red bottle.
However, I can't give the shampoo full credit for that because
I was also using a repair conditioner.

Hard to say how good this shampoo was, as I used it in conjunction with my conditioner. It smelt great and lathered easily. Did it repair my damaged dyed hair? Maybe not. It didn't make it worse though. Kind of expensive for a meh response.
