This hair color brand was recommended to me by a friend. We both have stubborn gray hair. Although she said she is happy with it, it did not really work with my thin gray hair. It did not cover well and after 2 wash, gray is too visible. Followed the instruction to the T, but even after washing it, I saw it did not cover. I thought perhaps it will hold and not wash off and unfortunately it didn't. Now I have to color it again just after two washes. :(
