After I gave an iron treatment, I put bleach on the hair for about an hour and the still came out with red and gold in it, what can I do to prevent that from happening?

I would let a professional do it for you next time. :)

Hair goes through different stages when you bleach it. If you are trying to go light brown or blonde, you will need to bleach your hair to a yellow stage and then deposit the desired color. Bleaching the hair is a difficult process. If you want to go 3 or 4 shades lighter, your best bet is to let a professional color your hair.
