Supplements

Biotin for Hair/Skin

Only helps the rare true deficiency; for everyone else it just distorts lab tests.

Also called: biotin · vitamin b7 · hair skin nails

✕

Verdict — cope

The mechanism does not hold. Your time is better spent elsewhere.

D

Evidence grade D

Nobody has demonstrated this works. Note that this grades the evidence, not the danger — read the verdict for that.

Mechanism

Cofactor for carboxylases; supraphysiological doses have no demonstrated effect on hair growth in non-deficient individuals.

The full read

Biotin deficiency is genuinely rare outside specific conditions. Trials in healthy adults show no hair benefit, and megadoses interfere with troponin and thyroid lab assays — a real clinical hazard. The 'hair, skin & nails' aisle is riding one micronutrient's halo.
