From the Microbiome to the Hair Follicle: The Hidden Science of Hair Loss with Dr. Andrea Echeverry

In this episode we’re diving into the fascinating world where science, scalp health, and the microbiome meet beauty and wellbeing. Hair loss isn’t just about vanity—it’s a window into what’s happening beneath the surface. Our guest is Dr. Echeverry and in this episode we will speak to what really drives hair loss, how the microbiome and immune system influence the follicle, and why restoring balance—not just applying treatments—is key to long-term hair and scalp health. Dr. Andrea Echeverry is a biologist with a Ph.D. in Microbiology and Immunology from the University of Miami and a B.Sc. in Microbiology and Biotechnology from Florida Atlantic University. After pioneering neonatal mouse models for intestinal infection research, she shifted her focus to the intersection of the gut, skin, and scalp microbiome—especially its role in chronic inflammation and hair loss. For over 14 years, Dr. Echeverry has collaborated with barbers, dermatologists, and hair transplant surgeons across Florida, Georgia, and Puerto Rico to highlight the microbiome’s vital role in scalp and hair health. Combining trichology, microbial ecology, and micropigmentation, she helps clients restore both hair and confidence. A passionate educator and advocate, she promotes hair loss prevention among young adults and is producing a bilingual web series sharing real hair loss journeys. Dr. Echeverry also serves on the Executive and Educational Boards of the Association of Professional Trichologists (APT), where she is the immediate past President and Treasurer.
