Episode 213: USDA New Food Guidelines & What That Means For Your Hair

In this episode, I’m joined by functional medicine expert Dr. Sam Shay to explore the difference between genetics and epigenetics, and how they influence health, autoimmunity, and hair loss. We talk about why having alopecia doesn’t necessarily mean it runs in your family, and how factors like stress, nutrition, sleep, and environment shape how genes are expressed.

Dr. Sam breaks down complex genetic concepts in a clear and empowering way, explaining why people with the same genes can experience very different health outcomes. This episode also introduces a new step forward for Alopecia Angel clients by offering genetic testing. This creates even more personalized healing plans that support your body.

The main force behind Alopecia Angel is a deep desire to help individuals achieve what I achieved with a natural treatment option, a well-rounded approach to health, wellness, and reversing Alopecia naturally without antibiotics, pharmaceuticals, cortisone shots to the head, or embarrassing creams.
