Scientists Accidentally Discover Cure for Baldness

Mouse researchers conducting stress hormone experiments have stumbled onto a surprising new discovery — a potential treatment for hair loss.

Scientists at the University of California, Los Angeles, and the Veterans Administration were working with genetically altered mice that typically develop head-to-tail baldness as a result of overproducing a stress hormone.

The experiment wasn’t focused on hair loss. Instead, it was designed to study a chemical compound that blocks the effects of stress on the gut. The researchers treated the bald mice for five days with the compound and then returned them to the cages, where they scampered about with several furry mice from a control group.

Three months later, the scientists went back to the cage to conduct additional experiments. They were surprised by what they saw inside — all of the mice had full heads and backs of hair. The once-bald mice, eventually identified through ear tags, were indistinguishable from their normal, furry cage mates.
