Don’t do it!!! I died my hair nearly black once, and used that stuff to get it out and I wound up with ORANGE!! Very freaky color! Go to a professional to get you hair back from black.
i’ve used it before, it’s called color oops extra strength hair color remover.
I tried to dye my hair dark brown and it ended up black. :/
The hair color remover is really good, infact you can use it to remove the color and it’s gentle enough so that if you wanted to you could dye it again the same day.
It didn’t do much, if any damage to my hair and it brought it back to it’s natural color.
