I dyed my hair black a month ago and then I dyed it red but it didn't work, maybe red was to dark?? I don't know but I was going to get the black chemically removed but a friend told me to dye my hair blonde and then dye it red
Will it work?

Sweetie, if your hair is black and want a decent red shade, you would have to pre-lighten your hair with bleach and then deposit the desired color. Do not apply box colors over your hair to try to make it red, it will ruin your hair. I recommend that you go to a salon and have the coloring process done.
