Sharon Osbourne’s trademark red hair is no more.

Yep, in news that will send ripples throughout the entertainment world – and will send sales of red hair dye plummeting – the former X Factor judge now has a shock of white hair.

And it’s very Miranda Priestly…

Let’s contrast and compare…

Uncanny. 

Sharon enlisted celebrity colourist Jack Martin – the man responsible for Jane Fonda’s grey pixie cut debuted at the Oscars – who revealed Sharon’s new look on Instagram.

He shared side-by-side pictures showing her old look alongside the new white hair and explained why she decided to change.

“Sharon has 100% white hair and she was colouring her hair once a week dark vibrant red for the past 18 years,” he wrote.

“She explained to me that she wanted to do this transformation a long time ago but every time she attempts it ends up with a disaster.”

Jack said it took a total of eight hours to dye Sharon’s hair, adding she would no longer need weekly touch ups.

Phew.

The celebrity hair stylist made headlines earlier this month when Hollywood star Fonda, 82, debuted her new grey pixie cut while presenting Best Picture at the Oscars.

Sharon has been married to heavy metal star Ozzy Osbourne since 1982.

Last month the couple made an emotional appearance on Good Morning America where Ozzy revealed he had been diagnosed with Parkinson’s disease.
