Y.C.
For me it didn't work as well as I wished, but maybe I didn't used right.
In the commercial it looks like you had enough product to saturate your hair as if it was a shampoo but when I used I barely had enough and it dry very fast so it wasn't really like using shampoo, also it did cover my grays but just as much as my normal old fashion color hair.
But it doesn't hurt to try.
However the after color hair treatment was great, I really like that one.
