Tried this out on permanently dyed black hair as well as virgin dark brown hair (my roots). Was able to get a touch of color onto the ends, but even on the virgin hair, it was a yucky yellow color. Not bad if you're looking to put color in, but I wouldn't rec going full on blonde with this one.
-NEVER bottle up or close the lid on the activated bleach. IT WILL explode (I forgot and almost had this happen)
-NEVER try to bleach permanently dyed hair. It will only pull a brassy brown color, and even then if you are aiming to dye, it is really hard to stick any color to it.
