Movember 2011 officially comes to an end on Wednesday, after a month of moustaches and Mo Bros and Mo Sistas raising millions of dollars for men's health.
Along with participants from all over the world, celebrities like Brody Jenner, Kevin Connolly and Mark Hoppus also pitched in this year.
Like previous years, the sports world also dominated with teams of moustaches.
The National Hockey League alone has raised close to $200,000 for Movember, thanks to teams like the Anaheim Ducks and the Nashville Predators.
Last week, Canadian superstar Justin Bieber promoted Movember on The View, when the ladies of the morning talk show asked about his facial hair.
Famous Mo Sistas have also been raising millions for Movember. In October, actress Malin Akerman (Watchmen) made a video called It's Moustache Season and has appeared at several charity events, a Movember spokesperson told IB Times.
Since 2003, the Movember foundation has raised awareness and millions of dollars around the world for men's health issues like prostate cancer and depression. In 2007, the US chapter of the organization was created, followed by chapters in Canada, the UK and South Africa.
With donations still rolling in, Canada's Movember chapter is leading the way with more than $33 million raised. Australia is second with $22 million, followed by the UK at $21 million, and the US at $11 million.
On Twitter, millions of Movember participants have been dominating news feeds with last minute donation requests. Hashtags like #movember and #goodbyemovember have been generously used by Twitter users.
The early numbers have already surpassed last year's figures. In 2010, more than 64,000 Americans raised $7.5 million for Movember, as proceeds were split between Lance Armstrong's LIVESTRONG foundation and the Prostate Cancer Foundation.
