Actress had a mishap with henna

Sienna Miller had to rub tomato sauce into her hair when she accidentally turned her locks green.

The actress, 27, resorted to the strange beauty treatment after she suffered a bad dye job.

When I went brunette, I dyed it with henna, not knowing it’s the worst thing you can put on blonde hair,’ Sienna tells Celebs On Sunday.

It went green and the only thing that would get the green out was tomato ketchup.

I had to sit with ketchup on my hair every week.
