I have used dark blonde all the way to dark brown an one of the reds (don't remember which) an attempt to achieve the color I used to get with another product. It all came out blonde except the red which came out reddish blonde. Most of my natural hair is now white, so no doubt this is why. The dark brown is the best, however, it's a bit more ash that I want. My natural color (prior to getting white) was brown with reddish highlights. What can I mix to get closer to that? My roots are now showing and it's time to place an order.
