Full show notes - https://bengreenfieldlife.com/prologue In this episode, stem cell scientist Dr. Yaron Fuchs reveals how an accidental lab finding, a compound that turned every hair white, led to Prologue, a peptide serum built to help you keep the natural hair color you still have. You’ll hear why hair goes gray in the first place, how the stem cells that run your pigment “factory” decide whether to live or die, and how his team shrank a large protein into six peptides small enough to reach the follicle. You’ll also learn the surprising story behind finasteride, from castrated men who never went bald to a rare mutation in the Dominican Republic, and why hair loss medicine has barely advanced in decades. We dig into what his clinical study found, when to start treatments if you want to stay ahead of your first grays, and whether a red light helmet has any real benefits for hair. You’ll also hear how I fit the serum into my morning routine, and how Dr. Fuchs’ lab can grow and test your own hair follicles from a urine sample.
