The No-Shave November rules are straightforward: Put down your razors, clippers, and trimmers for 30 days. For the entirety of November, you are forgoing shaving facial and body hair and are instead growing it all out.

The No-Shave November website suggests a few ways to get involved: "Participate by growing a beard, cultivating a mustache, letting those legs go natural, and skipping that waxing appointment."

Since you're skipping out on the barber for the time being, the association also encourages participants to donate their monthly hair-care expenses to the cause. Per the No-Shave November site, the contributions go to "investing in groundbreaking cancer research and providing free information and services to cancer patients and their caregivers."

However, No-Shave November offers alternatives for those who need it.

"Strict dress code at work? Don’t worry about it! We encourage [the] participation of any kind; grooming and trimming are perfectly acceptable," they write.
