No Shave November is an annual event that encourages participants to forgo shaving for the entire month of November. The initiative aims to raise awareness about various types of cancer, particularly prostate cancer, testicular cancer, and breast cancer. By letting their hair grow, participants symbolize the struggle many cancer patients face during treatment. The movement began in 2009 and has since gained popularity worldwide. Participants often share their progress on social media, using the hashtag #NoShaveNovember. The funds raised through this initiative are typically donated to organizations that support cancer research and education, such as the American Cancer Society.
