Hair can be our crowning glory, a big part of our identity, and a tool for self-expression. We shave it, style it, cut it, dye it — and sometimes, hope for it to come back. We obsess over its texture and length. While products help, how our hair looks is related to DNA, to hormones, and to our immune system. On this episode, we look into the connection between our health and our hair. We hear stories about the chemicals in hair dyes, treatments for baldness, and certain aspects of hair that can become an obsession.
