Goal-Based Guide
Hair health is primarily determined by genetics, hormones, and nutrient status. These supplements address the nutritional factors that experts actually discuss.
All 5 experts actively recommend omega-3 supplementation, making this one of the strongest consensus topics. Patrick and Attia provide the deepest mechanistic coverage, Huberman recommends 1-3g EPA for mood and cognition, Hyman lists omega-3 as a foundational supplement everyone needs, and Johnson includes omega-3 sources in his Blueprint diet.
All 5 experts view zinc as an essential mineral, though their depth of coverage varies significantly. Hyman is the most prolific advocate, citing zinc across immune function, gut healing, brain health, skin health, fertility, and detoxification. Huberman recommends 90-100mg zinc for cold prevention and includes it in fertility protocols. Patrick highlights zinc's role in immune defense, cold duration reduction, and its interaction with quercetin as a zinc ionophore. Attia mentions zinc as a critical micronutrient for testosterone optimization. Johnson includes zinc indirectly through his nutrient-dense diet but does not feature it as a standalone supplement.
All 5 experts acknowledge iron as essential, but the consensus is unusually nuanced: test first, supplement only if deficient, and monitor carefully. Attia provides the deepest biochemical coverage with a dedicated iron episode. Hyman includes iron bisglycinate in his personal daily stack and flags it as one of the most prevalent deficiencies. Johnson actively supplements heme iron for borderline levels. Patrick highlights excess iron as an aging accelerant. The universal theme is that iron is a double-edged sword — both deficiency and overload are dangerous.
4 of 5 experts support collagen for skin and connective tissue health, but Attia is notably skeptical — citing research showing collagen does not outperform whey protein for connective tissue synthesis. Johnson is the strongest advocate, taking collagen peptides daily in his Blueprint protocol. Huberman recommends it specifically for skin, not muscle. All experts agree collagen is inferior to whey for muscle building.
Addressing nutritional factors that affect hair:
Taking biotin without testing for deficiency. Biotin deficiency is actually rare, and supplementation rarely helps unless you are deficient.
Not checking iron and thyroid levels. These are the most common correctable causes of hair loss.
Worrying about creatine causing hair loss. Attia, Norton, and Candow have all debunked this myth.
Expecting supplements to override genetic pattern baldness. They address nutritional deficiencies, not androgenetic alopecia.
