Your Hair Is Telling You Something

Hair is one of the most metabolically active tissues in the body. When something is wrong systemically — a hormonal imbalance, nutrient deficiency, or metabolic dysfunction — hair is often the first tissue to show it.

DHT: The Androgen Connection

DHT binds to androgen receptors with double the affinity of testosterone and a dissociation rate five times slower. The difference between hair loss and hair retention is androgen receptor sensitivity, not DHT levels.

Thyroid: The Silent Hair Killer

Both hypothyroidism and hyperthyroidism cause diffuse hair loss. Subclinical thyroid dysfunction (TSH 3.5-4.5) can cause hair thinning long before formal diagnosis.

Insulin Resistance and Hair

In women, insulin resistance stimulates ovarian androgen production. In men, it increases 5-alpha-reductase activity and promotes scalp inflammation.

The Nutrient Deficiency Layer

A 2025 study found associations between hair loss and reduced iron, ferritin, copper, selenium, vitamin D, and B12. Ferritin below 40 ng/mL is associated with increased shedding.

The Longevity Medicine Approach

Comprehensive hormonal panel (testosterone, DHT, thyroid, cortisol, insulin), nutrient assessment, inflammatory markers, and metabolic assessment — then treat root causes before topical solutions.
