The Thyroid (and Hormone) Fixer Podcast

Episode 621: How to Fix Your Hair Loss

Host: Dr. Amie Hornaman
Date: April 14, 2026

Episode Overview

Dr. Amie Hornaman dedicates this episode to one of the most frustrating symptoms for those with thyroid and hormone imbalance: hair loss. She unpacks the multifaceted causes of hair loss, with a special focus on thyroid dysfunction, perimenopause, menopause, and related hormonal and lifestyle factors. Dr. Amie’s goal is to empower listeners to check off their personal “hair loss” boxes by understanding underlying causes and practical solutions.

Key Discussion Points & Insights

1. Understanding Hair Loss Timing & Triggers

• Delayed Response:
  Hair loss often shows up months after a triggering event, not right away.
  Quote:

  “When you're experiencing that, it’s going to be something that occurred months ago... Hair goes through a hair growth cycle.” (15:37)

• The “Telogen Effluvium” Effect:
  Stress (emotional, physical, viral like COVID-19) pushes hair follicles into a resting/shedding phase, usually manifesting thinning and loss several weeks later.

• Examples of Triggers:

  • Major life stressors: death, divorce, job change, moving
  • Acute illness or viral load (e.g., COVID-19)
  • Hormonal changes: perimenopause, menopause, pregnancy
  • Nutrient deficiencies, medication changes

2. Autoimmunity and Genetic Factors

• Hashimoto’s & Alopecia:
  Autoimmunity begets autoimmunity. Women with Hashimoto’s are more likely to develop alopecia areata (patchy, autoimmune hair loss).
  Key action: support the immune system and control inflammation.

• Genetic Predisposition:
  Some hair loss patterns can be inherited but often overlap with nutrient or hormone issues.

  Quote:

  “If you’re looking at your parents and you’re like, ‘Mom and grandma had a bald spot on the back of their head,’... Did they not take hormones, and that’s the reason?” (32:11)

3. Nutrient Deficiencies & Dietary Factors

• Ferritin:
  “Check your ferritin! If ferritin is low, it’s not really a good situation for anything thyroid related.” (25:11)
  Aim for at least 80-100 ng/mL, especially if you have Hashimoto’s.

• B12 Deficiency:
  Especially common with vegan/vegetarian diets, metformin use, and lack of B complex supplementation.

• Protein Intake:
  Insufficient protein (especially animal-based) can dramatically impact hair health.
  Goal: 1 gram per pound of lean body mass per day.

• Other Nutrients:
  Vitamin D, magnesium, selenium, iodine all play supportive roles in hair health and hormone balance.

4. Hormonal Imbalance

• Estradiol & “Old Lady Hair”:
  Dropping estrogen in menopause or from lack of HRT leads to scalp visibility and thinning.

  “Hormones are absolutely key when it comes to hair and hair quality.” (29:44)

• Testosterone/Androgens:
  Excess androgens (from PCOS or over-supplementing with testosterone/pellets) cause male-pattern thinning.

• Hypothyroidism:
  The thyroid is the “master gland” — slow thyroid means impaired blood flow and nutrient delivery to follicles, improper hormone production, and disruption of the entire hair cycle.
  T4-only or T4-dominant treatments can elevate reverse T3 and worsen hair loss in poor converters.

5. Medications and Medical Interventions

• Medications That Can Cause Hair Loss:

  • Birth control pills (tank progesterone, can induce hypothyroidism)
  • Antidepressants (often used as a thyroid symptom band-aid)
  • Blood thinners, steroids, beta blockers, chemotherapy, radiation

• Risks of Birth Control in Midlife:
  Using birth control to manage perimenopausal symptoms can disrupt natural hormone production, leading to metabolic and hair problems.

  “Putting a 40-year-old premenopausal, perimenopausal, menopausal woman on birth control is pretty much a medical crime in my eyes.” (41:12)

6. Blood Sugar, Stress, and Inflammation

• Insulin Resistance:
  High blood sugar and insulin from hypothyroidism or stress increase inflammation — a direct enemy of healthy hair follicles.

• Cortisol:
  Chronic stress raises cortisol, which disrupts glucose and further fuels inflammation/hair loss.

• FSH & Bioidentical Hormones:
  High FSH (>25) means low estrogen and increased inflammation; optimizing with bioidentical hormones can rebalance this.

7. The Fix-It Approach: What To Do About Hair Loss

Stepwise Action Plan:

1. Fix Your Thyroid:
   Get optimal—not just “normal”—thyroid treatment. Address reverse T3 if on T4 or NDT only.

2. Address Hormones:
   Use bioidentical hormone therapy (where appropriate) to support estradiol, progesterone, and avoid excess androgens.

3. Tackle Stress & Blood Sugar:
   Tools like berberine for blood sugar, managing stress, and adequate sleep/rest.

4. Nutritional Optimization:

   • Ferritin up to 80-100+
   • 1g protein/lb lean body mass
   • Supplement B12, vitamin D, magnesium, selenium, iodine
   • Address low ferritin, low B12, low vitamin D

5. Monitor Androgens:
   Avoid excess testosterone or androgen-pushing therapies (especially pellets), particularly if hair loss accelerates.

8. Biohacking & Medical Hair Restoration

Biohacking Tools:

• Dermal Rolling:
  Use with growth-factor serums like GHK-Cu (copper peptide) for scalp health.

• Red Light Therapy:
  Prefer targeted red light (e.g., Mitolux box) over weak red light caps.

  “Just get a red light… Red light directly on my hair.” (56:00)

• PRP (Platelet-Rich Plasma):
  Effective but only when done professionally—consider only in advanced/severe cases.

• Advanced Peptides:
  Peptides like BPC-157, TB-500, Ipamorelin may have benefit (see linked episodes for deep dive).

• Basic Hair Practices:
  Don’t over-bleach, don’t over-heat style, use protectants, be as gentle as possible.

Key Reminder:

“Try all of the remedies that we just talked about today first… Don’t waste money. Do all of the simple things that are in your control first.” (01:00:15)

Memorable Quotes & Moments

• On the “Delay” in Hair Loss:

  “Whenever we are losing our hair, we have to look backwards… it’s going to be something that occurred months ago.” (16:12)

• On Women’s Frustration:

  “Fatigue, brain fog, the weight that will not come off, mood swings, hair loss, feeling dismissed, frustrated and confused. I get it.” (06:22)

• On “Normal” Lab Ranges:

  “Now that I’m listening to this, I’m realizing it’s not normal. This is not in a normal range or in an optimal range. My doctor is just looking at it as part of the standard lab value range.” (11:01)

• On Hormones in Menopause:

  “There’s no badge of honor for going through menopause miserable. There really isn’t, ladies.” (30:28)

• On Converting T4 Medication:

  “NDT is 80% T4… If you’re not a good converter, then you’re going to get worse… Too much T4 increasing reverse T3 also causes hair loss.” (47:00)

• On the Emotional Side of Hair Loss:

  “All we want is our beautiful head of hair back… just go through this show again, replay it, stop it, pause it, take notes and make sure that you are checking all the boxes.” (01:08:05)

Summary Takeaways

• Hair loss in women with hormonal and thyroid issues is multifactorial and usually delayed by months after a trigger.
• Most conventional lab ranges are inadequate—seek functional levels especially for thyroid hormones, ferritin, and sex hormones.
• Optimize thyroid, replace hormones with bioidenticals as needed, balance nutrition (especially protein and iron), and manage stress/inflammation.
• Utilize topical and non-pharmacological hacks after foundational work is complete.
• Emotional impact is real and valid; seek support and don’t assume “normal” labs mean “nothing’s wrong.”
• Don’t give up.
