Sienna Miller's Natural Hair Remedy
"I've had pink hair — when trying to dye it red — and green hair, when trying to dye it brown. I just couldn't get it back to normal. The only thing that made any difference was ketchup, so for about a year-and-a-half I had to put tomato ketchup on my hair under heat until it went back to normal. And this wasn't even a childhood mistake — I was about 22 so it was all very silly and very public," Sienna Miller told Vogue UK.
