How Did Humans Start Going Bald?

Every day, millions of men look in the mirror and notice their hairline moving back. We spend billions of dollars on creams, pills, and surgeries trying to stop it. We view baldness as a mistake of the human body. A loss of youth. But what if it isn’t a mistake? What if losing your hair is actually one of the oldest, most misunderstood survival signals in human history? In this video, we travel back millions of years to the open savanna to understand why humans kept the hair on our heads—and why the body randomly decides to drop it as we age. We explore the genetics of DHT, the curious case of the bald macaque, and the "Social Maturity Hypothesis," which suggests a receding hairline was an ancient badge of honor. Before mirrors existed, what did early humans think when they lost their hair? Welcome to Unseen Us.
