This monologue podcast, Health Hacks, focuses on the root causes and potential treatments for hair loss. Dr. Mark Hyman begins by explaining the role of androgenic alopecia and DHT, then details other contributing factors like hormonal imbalances, insulin resistance, inflammation, nutrient deficiencies, and stress. He outlines dietary changes (reducing sugar and starch, increasing fiber and healthy fats), supplementation (biotin, vitamin B12, vitamin D, zinc, omega-3s), and lifestyle adjustments (stress management, sleep improvement) to address these issues. Finally, he discusses medical treatments like Rogaine, Propecia, and spironolactone, alongside alternative therapies such as PRP and LLLT, emphasizing the importance of testing (via Function Health) to determine individual needs. Listeners gain a comprehensive understanding of hair loss and actionable steps for improvement.
