i havn't added any colour into
or changed any part of it
thats just how my hair looks when the suns on it and i have flash on my camera.

I am sick of everyne asking how I did it, so just read this.

I used la riche hair dyes, they're easy to use, just wet your hair slightly, and rub in the dye until it turns a creamy texture, then leave for half an hour and then wash it out.

Well the dark colour is what happened after 2 years of dying my naturally dark brown hair black. It went that reddy colour in the sun.
I didn't die it rainbow colours on purpose, when I first started dying I had a green fringe, then blue, then purple, then pink, then I dyed it green and purple striped [vertically] and it came out like this, it was purely by accident but I loved it!

I had it like that for 2 or 3 weeks, because I liked it so much, but then I got bored and dyed it so it faded from pink at the top, to purple, to blue, to turquoise, which I also loved, but that only lasted a few days.
