I heard lemon juice, then lay out in the sun. Sunlight always lightens hair, and lemon juice speeds that all up. I've never heard of lemon juice harming dyed hair...
get high light colors that are all natural

especially amonia free



Good luck and hope i helped =]
lemon juice and sunlight is pretty good.



Don't wash your hair for a while, then when your hair is greasy the oils will protect it from the acidic lemon juice.
