First I saw it in EGG model Kanako.
I really like the way those two colours match. She lately quited that style up but kept on two-tone through extes.
Some gals really rock it trying crazy colours, like this girl (but I'm DEFINITELY not so brave lol):
This year (? not sure) also appeared a new trend: two-tone in horizontal gradation:
So...now I'm considering WHAT in the world to do. I can always try with extes and see how it works on me before go bleaching or something like that, but anyway I'm not sure about which colours I should mix. I would like to dye my hair like auburn, maybe cinnamon, so which colour would you add to it? Dark brown? Black? Red blonde? (brrr, blonde, I can't see me in blonde lol) :S
