Healthy, vibrant hair is often seen as a sign of overall wellness, but for many of us, achieving that shiny, full head of hair can feel elusive. We often see patients whose hair concerns are tied to deeper imbalances in the body.

Let’s explore what really affects hair health and how you can support it. From hormonal imbalances to nutrient deficiencies, digestion and toxic load.

Hormonal imbalances

Your hair follicles are highly sensitive to hormonal fluctuations especially:

  • Thyroid hormones: hypothyroidism can lead to thinning hair
  • Estrogen and progesterone: imbalances can trigger shedding during perimenopause or postpartum.
  • Cortisol: chronic stress can push hair into a resting phase, leading to shedding.
  • Testosterone and DHT: can cause thinning around the hairline or crown.

Nutrient deficiencies

Hair growth relies on key nutrients like:

  • Iron: low iron stores, especially ferritin, can cause shedding
  • Zinc: essential for hair follicle health
  • B vitamins: especially biotin, B12 and folate.
  • Protein: your hair is made of keratin, a protein

Digestion & Absorption

Aside from eating well in terms of quality and quantity we have to think about the ability to produce the necessary enzymes to extract nutrients from food and keep inflammation at bay. Poor stomach acid or gut inflammation can block nutrient absorption, starving your hair from the inside out.

Toxin Load

Whether it’s heavy metals, endocrine-disrupting chemicals, and/or chronic inflammation can stress the body and affect hair growth cycles. The body can deal with a certain amount of toxicity but with the level of exposure that we have nowadays its important to detox properly and regularly.

Recommendations

  • Support your adrenal glands with adaptogenic herbs live ashwagandha and/or rhodiola.
  • Keep blood sugar stable
  • Include iron rich foods (grass-fed meats, dark leafy greens, lentils) paired with vitamin C sources (bell peppers, broccoli, strawberries) for absorption.
  • Prioritize protein with every meal
  • Consider bitters or digestive enzymes to support stomach acid
  • Prioritize sleep and rest
  • Stress management techniques like meditation, breathwork or gentle yoga
  • Support your detox pathways by ensuring daily bowel movement, sweating regularly and staying properly hydrated.

Hair health is a reflection of your whole body health – hormones, digestion, detox, and stress all play a role. If you’re struggling with hair loss or thinning, consider working with a naturopathic doctor who can help you uncover the root causes and craft a personalized plan.
