Natural blonde with dyed brown hair... wanting to go back to blonde

Im a natural blonde. I dyed my hair dark brown, and now im wanting to go back to my semi-light blonde hair color.

Help please?

number one you messed up big time because you were supposed to slowly die it to some what help your hair get used to it.

Bleaching can be really damaging to the hair especially the home bleaching/dying kits so I recommend you get it done proffessionally at a hair salon. But it will still probably damage your hair some what. Using a blonde dye will most likely just turn your hair ginger so usually you have to bleach it about twice first and then dye it to the desired colour.

Just get some highlights and wait for it all to grow out so you can start again with natural hair (easier to work with).
