Sharon Osbourne has undergone a striking a new transformation by having her iconic dark red hair dyed white.

The new look was posted to Instagram yesterday by celebrity colorist Jack Martin, who explained in the caption that the British TV personality had been dying her hair red for nearly two decades - but had been wanting to change it up for a while.

He wrote: "Another great day in my career welcoming the most beautiful and elegant talk show host and entertainer @sharonosbourne for a complete transformation. Sharon has 100% white hair and she was coloring her hair once a week dark vibrant red for the past 18 years."

Jack continued: "she explained to me that she wanted to do this transformation long time ago but every time she attempts it ends up with a disaster. Sharon was very tired of coloring her hair once a week and she was obligated to since she is on tv almost every day hosting her popular tv show @thetalkcbs."

"I didn’t promise Sharen anything but I told her I will try my best, it took me a total of 8 hours from start to finish to get her to a platinum blonde so she doesn’t have to be committed to coloring her hair once a week anymore. I had great time spending my day off with this gorgeous, humble, and sweet soul."

Stunned by Sharon's drastically different hair color, a number of fans took to the comments to share their thoughts.

One person wrote: "Love love this ! I’m a Brit too ...and I Love Sharon! I recently lost my hair due to chemo and would love to try platinum as my hair is now coming back in !"

Another added: "YOU ARE A LEEEGENNNND JACK!! You only deserve the best. this is absolutely STUNNING!"

A third shared: "I knew it it’s her .... the moment you showed us the sneak peek pic .... amazing result,"

A different fan gushed: "YOU ARE A LEEEGENNNND JACK!! You only deserve the best ❤️❤️❤️❤️❤️❤️❤️❤️❤️ this is absolutely STUNNING!"
