Evidence for hair

None of the study abstracts we summarised for HGH reported an outcome for hair (PubMed search, 2 Oct 2026). Claims that it helps with hair are unproven.

PubMed records for HGH and hair: 3 human, 2 animal (search counts, not studies we reviewed).

How strong is it?

Strongest evidence:No graded study for hair (PubMed search, 2 Oct 2026)

A human randomized trial outweighs any number of animal studies. Animal and cell results show a mechanism worth testing, not that it works in people.
