The Gut-Hair Connection: Functional Strategies for Hair Loss and Alopecia

Hair loss affects up to 50% of people during their lifetime, often taking a significant toll on self-esteem and quality of life. While conventional medicine primarily offers suppressive treatments, functional medicine uncovers the root causes—frequently found in gut health.
Dr. Julie Greenberg uses this transformative session to demonstrate how the GI‑MAPS® test can uncover hidden contributors to hair loss and alopecia areata (AA). Discover how gut microbiome imbalances play a role in these conditions and gain actionable insights to address them effectively.
Through compelling real-world case studies — including before-and-after photos and lab results — Dr. Greenberg will provide a clear roadmap to help you tackle even the most challenging AA cases with confidence.
