Could your thinning hair be more than a cosmetic concern—perhaps a signal of hidden hormone, thyroid, or nutrient imbalances?

In this must-listen episode of the Modern Thyroid and Wellness Podcast, host McCall McPherson sits down with functional medicine expert Dr. Breanne Kallonen to unravel the multifaceted causes of female hair loss. Together, they explore the often-overlooked connections between hormone imbalances, nutrient deficiencies, thyroid dysfunction, autoimmune disease, and metabolic stressors like insulin resistance.

Breanne brings her experience working with high-achieving women to highlight why generic treatments fail—and how personalized lab work, optimal (not just “normal”) ranges, and foundational lifestyle shifts can lead to sustainable hair restoration. This conversation goes far beyond cosmetic concerns and positions hair loss as a valuable signal of deeper health imbalances.

Key Topics Covered

The top causes of hair loss in women: low iron, vitamin D, hormone shifts, thyroid dysfunction, Hashimoto’s, stress, post-viral inflammation, insulin resistance
Why "normal" lab values aren’t enough—what to look for in optimal ranges, especially for ferritin and thyroid
The strong correlation between iron deficiency and genetic hair loss (androgenic alopecia)
Comprehensive lab testing strategies: what to run, how to interpret, and why history matters
The role of metabolic dysfunction (especially insulin resistance) in accelerating hair thinning
Why many women are overprescribed testosterone—and how excess levels can backfire for hair health
The connection between gut health, inflammation, and nutrient absorption
Nutrition foundations: protein, fiber, vegetables, and identifying deficiencies
Short-term interventions (like red light therapy or collagen) to stimulate follicle activity while working on root causes
Importance of realistic timelines—what results you can expect in 3, 6, or 9 months depending on the root issue

Practical Advice for Listeners

Run comprehensive blood panels including TSH, Free T3/T4, ferritin, serum iron, insulin, vitamin D, and inflammatory markers
Prioritize protein intake (100g/day minimum) and track it honestly for a few days
Focus on metabolic flexibility—avoid extremes in diet unless indicated by labs
Address sleep, hydration, stress perception, and movement as foundational support
Be cautious with high-dose testosterone pellets or HRT—work with a clinician who monitors blood levels and risks
Expect 6–9 months for meaningful hair regrowth depending on the underlying cause—this is a long-term game
