the claim

Zinc supplementation reduces hair loss in people with thinning hair.

the verdict
INSUFFICIENT LEANING
Recorded sources
0 sources for · 2 against

Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that zinc supplementation reduces hair loss in people with thinning hair?

Unclear. The retrieved items do not test whether zinc supplementation reduces hair loss. Two studies report only that zinc levels are slightly lower in people with hair loss, and one of them explicitly calls that difference clinically insignificant and advises against routine zinc testing; no item measures a supplementation effect on hair thinning.
