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."

Social media has a huge influence on skincare routines, often promoting complex do-it-yourself regimens aimed at keeping a youthful appearance. But dermatologists say many of these viral products are unnecessary, even if they feel nice, and some can cause more problems than they fix. Real experts recommend a simple routine including a gentle cleanser, moisturizer, and sunscreen with at least SPF 30. Protecting your face from the sun's UV radiation is crucial. Retinol creams and chemical exfoliants can help smooth out wrinkles, but should be used carefully. And those really expensive products? Many share the same ingredients as the much cheaper ones.
