In this evidence based and physiology driven talk you will learn why hair loss is not a cosmetic problem and cannot be fixed by topical products alone. What you are about to hear is rooted in metabolic science, hormonal signaling, nutrient traffic, mitochondrial energy, inflammation control and how hair follicles respond to internal messages of growth or conservation. You will discover why traditional protein advice fails, why a particular leafy green vegetable delivers more usable protein per calorie than eggs, and why improving all of this changes hair biology at the cellular level. This video unpacks insulin resistance, liver stress, hormone integration, thyroid interactions, cortisol communication, and how hair loss is one of the earliest indicators of deeper metabolic imbalance long before standard tests turn abnormal. This is not a quick fix. This is a root cause approach that aligns hair health with whole body health, energy resilience, longevity, and true biological repair.
