Kava--Kava. Maybe I am taking it wrong, but it did not relax me as I expected it to. I felt like I was taking a placebo.

I have very dark brown hair. It is difficult to get me bleached to very blonde. There is always a residual yellow cast that I have to deal with. This shampoo makes a real difference. Even though the directions don't recommend daily use I do use it daily and have never gotten a purple color on my hair. It is a gentle shampoo and seems to even improve my hair's condition. I like the conditioner as well.
