I have been dying my hair medium blonde before using this color. I have medium thick hair to mid back and there was plenty to cover all my hair in one application. The first coverage/box was lighter than I expected, a real strawberry blonde - lighter than on the box. The second time I used it 3 weeks later, went a little darker but still lighter than on box. This may be because of the blonde under. My hair feels great after using it even so close together. I am using it with other L'Oreal color shampoos/conditioners. I hope I don't get any fading this time like I did the first time. If you are looking for a good strawberry/soft red/copper, this is the one to pick.
