Gay actor John Barrowman has revealed that his natural hair colour is “completely white”.

The Torchwood star, 42, said he had been dying his hair for years and that his civil partner Scott Gill, an architect, persuaded him not to go back to his roots.

“My hair’s only still the same colour because of the bottle,” he said told Attitude magazine.

“I’m completely white. Scott and I tested it out a couple of years back. I shaved my head and let it grow and no one saw it.

“I let it come out grey to see if it was time to let my hair go back to its natural colour. He looked at me and said: ‘I’m not so ready for that yet’. And he’s older than me. He’s 47 this year but looks like he’s 20.”

Barrowman added that he wanted to adopt, although he did not know if his partner was ready yet.

He said: “I think it’s important for gay men to adopt or to have their own kids, because then we can instill our own values in those children.

“Gay couples have a lot to offer. I don’t care what anybody else says, any home that shows love and tenderness and care to a child is a home that deserves to have children in it.”
