Hi, my name is Rebecca Foote and I currently have blue hair. It's super great and I love it. Not that I don't like my natural dark brown hair, but having colored hair is fun and I feel this suits me.
In the past few years, my hair has been silver, which quickly faded to blond; rainbow, which faded to mostly blue, then eventually down to a seafoamy green; hot pink; my natural color; and now blue. It started as an electric blue, but now is more of a teal as most blues end up.
