A Watford man is taking his Movember challenge one step further, by not only dying his moustache, but by offering people the chance to choose which colour.
Martyn Dyer, from Stripling Way, is taking part in the month long fundraising challenge which sees men across the world grow sponsored facial hair.
The 41-year-old said: "I first did Movember two years ago shortly after my cousin’s husband, Steve Brister passed away.
"Steve heard about Movember but sadly never had the chance to do it, so we all did so in his honour.
"During his illness Steve and his close family were supported by BT Buddies, a charity devoted to bringing awareness in treatment for brain tumour sufferers.
"I'm raising funds for this charity which helped Steve and the family out in his the last weeks and months of his battle."
Mr Dyer is offering people the chance to vote for which colour he should dye his moustache, costing one pound at a time.
He coloured his ‘mo the first time around in a similar stunt, except he used nail varnish.
Mr Dyer said: "I don't yet know what colour it will be until voting closes, at the moment its blue.
"The nail varnish was easy to get off, I just shaved it on the December 1, but this time round I want to have it done professionally."
