I had long been longing for a shampoo like this. The shade seemed to cause a color change, and probably even more with longer exposure time. Unfortunately, in use, my hair became lifeless and tangled. I finished with my trusted conditioner, but in the shower, hair broke and fell out relatively a lot. On the top of my head, hair was sticking out broken. It's frustrating because I have had a successful years-long hair growth project. Maybe it suits some hair types. I normally have fine but abundant hair, and the product was not suitable.
