Hair loss is often dismissed as a cosmetic issue—but what if it's actually one of your body's earliest warning signs?
In this episode of the Curious Cardiologist Podcast, Dr. Sanjay Bhojraj sits down with Johanna Dahlman, founder of Alopecia Angel, to uncover the root causes of alopecia and why conventional medicine often falls short.
After developing autoimmune alopecia in her early 30s, Johanna spent four years researching nutrition, functional medicine, lifestyle interventions, and autoimmune health before naturally restoring her hair. Today, she has helped thousands of people in more than 68 countries navigate hair loss by addressing the underlying drivers—not just the symptoms.
Together, they discuss autoimmune disease, gut health, stress, genetics, medications, supplements, hormones, pregnancy, longevity, and why hair loss is often a sign that something deeper is happening inside the body.
Whether you're experiencing hair loss yourself, supporting a loved one, or simply interested in preventative health, this conversation offers practical insights and a hopeful perspective.
Topics discussed:
✔ What alopecia really is
✔ Autoimmune hair loss
✔ Functional medicine
✔ Gut health and the microbiome
✔ Stress and chronic inflammation
✔ Hormones and women's health
✔ DNA testing and personalized medicine
✔ Hair loss medications
✔ Supplements that may actually worsen hair loss
✔ Why "aging" isn't the whole story
✔ Hair regrowth through lifestyle changes
Johanna also shares her personal journey of overcoming autoimmune alopecia naturally after being told there was no cure, and explains how that experience led her to help thousands of people worldwide.
If you've ever wondered why you're losing your hair—or what your body might be trying to tell you—this episode is for you.
