I bought this as an effort to stop buying plastic, I am usually really fussy about my shampoo but I thought its time to go more eco. I was not at all disappointed - it is great for my grey hair, seemed to enhance the colour and also not drying at all which I thought a soap bar would be. Above any high end brands like Redken, Kerastase, etc. Highly recommend. And use with the Purple conditioned for best result.
