We know mustaches are often accompanied with the facial hair trend and here is another reason to partake in the style craze: “Movember.”

The entire moth of November hundreds of thousands of men will put the razor down and grow it out in all shapes and sizes to raise awareness for testicular and prostate cancer and men’s mental health issues.

It’s also never to late to get your ‘stache’ going.If you have not gotten in the race, sign up. But first, you should know there are a few rules to abide by as a ‘Mo Bro.’

1.Start Clean
Head starts are not allowed for this cause. Participants are asked to have a clean shaven face.

2. Keep Clean
While you might be raising awareness, you don’t want to be raising eyebrows at the office. Keep it brushed and groomed.

3. No Faking
Beards and goatees? Nah. It’s about the mustache (and we don’t mean a glue on) and make it your own which means a little pomade may be  good thing.

4.You Got the Power
Your stache is a great conversation piece and way to talk about raising awareness for prostate and testicular cancer and men’s mental health.

5.Keep it Classy
Says the movement: “Each Mo Bro must conduct himself like a true gentleman…”

So what happens if your not a dude?

For people who like to run, there is also the “Mustache Dache,” which will take place throughout November in cities across the U.S. See if your city is ready for a marathon.

And while, women do not need to grow a mustache, they can raise funds and awareness for men’s health, and much more.
