It didn't work well at all for my hair (straight thick hair oily at the roots drier at the ends). It feels like it doesn't even clean the hair even with two hands. In terms of quality, it reminds me more of supermarket shampoo. I wouldn't buy it again for anything.

It maintains the artificial blonde color of the hair without altering it.
It protects the hair and gradually you see an improvement in the hair when you use the same product continuously for a few months. I don't change it.
