I adore two tone hair, and I finally got around to dye my own hair like that also. At first this was supposed to be just a transition phase while getting my hair lighter but I am loving this so much that I wanna keep it
I have two-tone hair unintentionally. I use anti-acne lotion that bleaches hair, (And clothes if one is not careful.) so the hair towards the front of my face is bleached. It actually results in a nice addition to my shaggy medium blonde hair, and the lotion works magnificently, so I won't be stopping any time soon.
