mmm you can use lemon juice apparently that work but I drys your hair out heaps.. or you can get this spray I think its called sunkissed you can get at most shoping centers and chemists.. it slowly lightens it when you go out in the sun... You can also get a tint done at the hairdressers.. is its a dye and will only lighted in a little as I am bleach blonde I get the tint done on my roots
