Are mycotoxins causing your hair loss?

Mycotoxins could be behind your hair problems

Often among the first complaints from people with mycotoxin problems is hair loss. This is a big issue among women. That's why I want to tell you today a bit more about why it happens.

How Mycotoxins Affect Hair & Hair Growth

Mycotoxins (like ochratoxin A, aflatoxin, trichothecenes, zearalenone, etc.) do not usually attack hair follicles directly. They damage the systems that hair depends on. The result can be:

  • Hair thinning

  • Excessive shedding

  • Slow growth

  • Brittle, weak hair

  • Changes in texture

Here’s how it happens:

Inflammation of the Scalp & Hair Follicles

Mycotoxins trigger systemic inflammation and oxidative stress.
This can lead to:

  • inflamed hair follicles

  • increased sensitivity of scalp blood vessels

  • miniaturization of hair follicles

  • Telogen Effluvium (stress-related shedding)

Inflammation tells the body: “Stop growing hair, focus on survival.”

Hormonal Disruption

Certain mycotoxins (especially zearalenone) behave like estrogen mimics.
This can cause:

  • estrogen–dominant hair loss

  • disruption of normal testosterone metabolism

  • increased DHT sensitivity in the scalp → faster thinning

Hormones are extremely sensitive to toxins.

Liver Stress → Hair Loss

Hair health depends heavily on normal liver function.
Many mycotoxins damage the liver (ochratoxin A, aflatoxin, trichothecenes).

When the liver is overwhelmed:

  • nutrient conversion is reduced

  • detox pathways slow down

  • hormones become unbalanced

  • inflammatory molecules accumulate

The result: weak, thinning hair.

Nutrient Malabsorption (common with mycotoxins)

Mycotoxins irritate the gut lining and alter the microbiome.
This reduces absorption of several crucial hair nutrients:

  • Zinc

  • Biotin

  • Silica

  • Iron

  • B-vitamins

  • Essential fatty acids

  • Protein absorption

Without these nutrients, the hair cannot grow properly.

Impaired Blood Circulation to the Scalp

Some mycotoxins affect blood vessels and mitochondrial function.
Consequences:

  • reduced oxygen to the follicles

  • low nutrient delivery

  • slow hair growth

  • increased shedding under stress

Hair follicles are extremely energy-dependent.

Autoimmune Activation (in some cases)

Mycotoxins can aggravate or trigger autoimmune tendencies.
This may worsen:

  • alopecia areata

  • psoriasis of the scalp

  • seborrheic dermatitis

  • autoimmune thyroid issues → hair thinning

Thyroid Disruption → Diffuse Thinning

Many mycotoxins disrupt the thyroid gland. Effects:

  • slower metabolism

  • hair becomes dry, brittle

  • overall thinning

  • loss of outer-half eyebrows (classic sign)

Thyroid hormone is essential for normal follicle cycling.

Stress on the Adrenals → Cortisol-Induced Shedding

Chronic exposure creates biochemical stress → cortisol increases.
High cortisol causes:

  • Telogen Effluvium (stress shedding)

  • clogged hair cycle

  • brittle, weak hair

Typical "Mycotoxin Hair Loss" Pattern. People usually report:

✔️ Diffuse thinning (all over scalp)
✔️ Increased shedding in the shower
✔️ Dry, brittle, dull hair
✔️ Thinning at the temples
✔️ Slower growth
✔️ More breakage
✔️ Worsening after stress or poor sleep

Your doctor will not know about this problem. The most important thing about hair loss is acting before it is too late. First you need to know if your problem is caused by mycotoxins. Then, you need to take rid of them. Afterwards you can begin with a recovery plan.
