What color would blue/black hair go if u dyed it bright red?
I am thinking that your blue black hair is not a natural color… color does not life color… if you have regrowth, that will come up fairly bright, but your ends more then likely won’t change… and if they do, you won’t get the result that you are attempting to achieve… if you want to make big a change, you may want to visit a salon. If you choose to bleach it, you only need to bring it down to orange… orange is the underlying pigment of red, the red will not fade out as quickly, if that is your base.
