Hair Loss and Root Causes
By Dr. Navaneeth K. Unni•Published on 2028-05-02•Patient Group: Adults
Clinical Overview & Pathophysiology
Hair loss and thinning are somatic indicators of underlying physiological imbalances—such as thyroid changes, iron depletion, chronic stress, or nutritional deficiencies. To restore healthy hair growth, you must address the internal systems that supply oxygen and nutrients to the hair follicles during their active growth phase.
Key Clinical Facts & Indicators
- Thyroid-Driven Thinning: Sluggish thyroid slowing down follicle metabolism, causing diffuse hair shedding.
- Iron Depletion (Ferritin): Low iron reserves starving hair roots of oxygen, shifting them to telogen (shedding) phase.
- Cortisol Telogen Effluvium: Sudden, heavy hair fall occurring 2-3 months after a severe physical or emotional shock.
- Nutrient Depletion: Brittle, dry hair shaft indicating a lack of zinc, B-vitamins, or amino acid intake.
Lifestyle & Nutritional Guidelines
Incorporate iron-rich and protein-dense foods using the [Diet Planner](file:///tools/diet-planner). Track hydration targets to support scalp circulation with the [Water Intake Calculator](file:///tools/water-intake-calculator). If experiencing thyroid symptoms, read our [Thyroid Disorders](file:///services#thyroid) care or book an [Appointment Booking](file:///appointments).
Frequently Asked Questions
Q: What is telogen effluvium?It is a form of temporary hair loss that occurs after a major physical or emotional stressor (like childbirth or high fever), shifting hair roots into the shedding phase.
Q: How does thyroid health affect hair thickness?Thyroid hormones regulate the metabolism of hair follicles. An underactive thyroid leads to dry, brittle hair and diffuse shedding across the scalp.
