National Big Wig Day is an annual celebration observed on the last Friday of January, specifically on January 30. This day encourages participants to don their favorite silly wigs while also recognizing individuals as "big wigs." The celebration aims to promote fun and creativity, while also encouraging donations to the American Cancer Society, with a suggested contribution of at least $1. The day was created by Patty Sharkey, who initially shared a playful selfie in a wig on social media, which sparked widespread enthusiasm. National Big Wig Day combines elements of humor and charity, inviting people to showcase their wigs and support a meaningful cause.
