Clinical dose: 1000–2000 mcg

Why Copper for Hair

Copper plays a supporting role in hair. Required for iron transport (via ceruloplasmin), collagen formation, and antioxidant defense through superoxide dismutase (SOD). Copper and zinc compete for absorption—high-dose zinc supplementation (above 50 mg/day) can induce copper deficiency over time.

What dose to look for

Clinical studies typically use 1000–2000 mcg of copper. Products below this range may not deliver meaningful results.

What form to look for

Avoid copper oxide — poorly absorbed. Look for copper bisglycinate or copper gluconate for better absorption.

What the research says

Copper has strong clinical evidence for hair benefits. Essential cofactor for iron transport via ceruloplasmin and collagen formation via lysyl oxidase Learn more

Clinical research on Copper

LOW — mechanistic evidence only · 0.5–2 mg/day

•Essential for tyrosinase (melanin production) — copper deficiency causes premature graying
•Copper deficiency causes characteristic 'kinky' hair (pili torti) as seen in Menkes syndrome
•No supplementation RCTs for hair outcomes in non-deficient individuals
