More women are defying traditional beauty standards and finding empowerment by going without hair on their heads. For centuries, many cultures have viewed long hair as a symbol of femininity, health and fertility. But women are increasingly embracing a close-cropped or bare head as something to celebrate, whether they are bald by choice or due to medical conditions. Some have sought ways to support each other with social media posts, conferences, "baldie" groups and scalp care tips. The founder of a New York public relations firm who shaved her head 14 years ago opens a video podcast on YouTube with the phrase, "Being bald is sexy. It's an attitude. It's a luxury. It's a lifestyle."
