Friday 5 - Hair Loss Isn’t Random: 5 Tests That Reveal the Root Cause

Send us Fan MailHair loss is rarely random — and it is almost never just about iron or shampoo.In this episode of The Autoimmune Reset, VJ Hamilton explores the deeper physiology behind alopecia and autoimmune-related hair loss, and explains why standard blood tests often leave people stuck with answers but no real direction. Because while tests like ferritin and thyroid markers can tell you what is low, they rarely explain why the body is struggling in the first place.Drawing from both her own recovery journey and years in clinical practice, VJ shares the five functional tests she most often uses to uncover the hidden drivers of hair thinning and shedding. From gut health and nutrient absorption to hormonal rhythms, mitochondrial energy production, mould exposure, and food reactivity, she walks listeners through the upstream factors that quietly influence immune balance and hair growth.This episode reframes hair as a barometer of overall health — not the problem itself, but a signal that something deeper requires attention. If you’re tired of guesswork and want a more strategic, root-cause approach to testing, this conversation offers a clear, practical roadmap.Because when you understand the “why,” everything becomes more precise — and far less overwhelming.Key TakeawaysHair loss is often a symptom, not the root issueBlood tests show what’s happening, but rarely explain whyGut health determines nutrient absorption and immune regulationHormonal rhythms and stress physiology directly influence sheddingMitochondrial energy is essential for growth and repairHidden mould exposure can perpetuate inflammation and immune activationFood reactivity may contribute to autoimmune flaresStrategic testing prevents supplement guessworkAlopecia improves when underlying systems are supportedA personalised, systems-based approach is far more effective than chasing single nutrientsChapter Markers00:00 Why blood tests aren’t the full story02:10 Hair as a barometer of deeper health03:05 Gut testing: Microbiome Explorer vs GI Effects06:00 Hormones, cortisol and the DUTCH test08:10 Energy, nutrients and Metabolomix09:40 Mould and environmental triggers10:45 Food reactivity and immune load12:00 A root-cause roadmap for recoveryReady to go deeper and understand your own “why”? → Learn about the functional testing and 1:1 analysis I offer in clinic — the same root-cause tests I used to rebuild my own health, with personalised guidance so you know exactly what to do next.
