Britain's Got Talent 2008 winner George Sampson has had a hair transplant

George Sampson has had a hair transplant at the age of 23, saying he was worried baldness could "affect his work".

The dancer won the second series of Britain's Got Talent with a routine choreographed to the song Singing in the Rain.

He thinks repeated head spinning is partly to blame for a missing strip of hair down the centre of his scalp.

But he also says there are medical causes.

He's been our tour recently and has posted updates online.

"This is something I've been considering having done for years," he posted in a message to fans before the transplant.

"I have always been convincing myself I'm not worried or it's not a big deal but really it is.

"It's not only for my own confidence, but also being in my line of work which is very image-orientated."

The star Tweeted that the procedure was "all finished".

He says he's also lost hair through a medical condition called alopecia which he says was "caused by a lot of stress and [the] loss of a family member".

He blames genetics as well.

You can read his full message on Twitter.

The dancer made his name busking on the streets of Manchester as a child.

He was 14 when he won Britain's Got Talent in 2008, after failing to get through on the show's first series the previous year.

In the decade since, he's danced in the London West End musical Into The Hoods and acted in the TV show Waterloo Road.

But he's admitted to worrying that baldness might start holding him back.

He's kept fans updated through Twitter. This tweet says "I'M HAVING A HAIR TRANSPLANT TOMORROW".

"I spend so much time doing my hair... to try and cover up as much as I can," he says.

"I've decided I've had enough of that. I want my own hair. I am only 23 and balding seems like something which happens to older men."

The 11th series of Britain's Got Talent is taking place now.
