Cracking the Code: What Hair & Nails Reveal About Your Gut, Hormones, and Stress | Ep.12

Erin Jowett

Thinning hair? Brittle nails? It’s not just about aging or bad genetics—it’s your body talking.

Hair and nail symptoms are some of the most overlooked clues that something deeper is going on with your internal health. Whether it's chronic stress, poor gut absorption, hormonal imbalances, or nutrient depletion, these beauty-based complaints are often the first signs your body is out of sync.

In this episode, we’re breaking down:

The Real Root Causes Behind Hair and Nail Issues

  •  Why weak nails and hair loss are often linked to deeper issues like poor gut function, low stomach acid, chronic stress, and thyroid or hormone imbalances.
  • How your body prioritizes survival over appearance—meaning your hair and nails are the first to show signs of nutrient depletion.

Functional Nutrition & Testing That Go Beyond Bloodwork

  • The difference between blood tests and functional tests like Micronutrient Panels, HTMA, DUTCH, and GI MAP—and why these give you a better picture of what’s really going on inside your cells.
  • How minerals, hormones, and your microbiome all play a role in your body’s ability to grow strong hair and nails.

How to Start Nourishing From the Inside Out

  • What to include in your daily diet to support healthy hair and nails (hint: it’s more than just protein and biotin).
  • Why antioxidant-rich, polyphenol-dense, and mineral-supportive foods are critical for long-term cellular repair and growth.
  • The role of stress, inflammation, and hormone metabolism in how your body uses nutrients.

Your hair and nails aren’t just cosmetic—they’re communication. When we stop treating them like surface-level problems and start asking why, we unlock the power of root-cause healing.
