UHH. I need halp. Bleaching hair in progress - possible disaster to come?

The bleach depends on the volume number it is and the brand. If its really strong I dont think a week will be quite long enough. But I can tell you that if you use those dyes in your hair most likley your hair is going to turn a green color. Anything with the word "ash" in it, usually does no matter what color or type of hair you have!!! Hope this helps, and just wanted to let you know that in case it comes out green so you are not suprised.
