It comes out with the co-washing, too. You don't need shampoo to wash it away. I'd just wash your hair (wet and rinse along with co-washing) a bit more often to help the wash out along.

So sorry you have to go thru this. Maybe you should call Natural Instincts and complain, since you did buy blonde, there is no way you should be brown now, especially considering you were blonde to begin with.
