Millet Seed Extract

A hair supplement ingredient always paired with L-cystine, biotin and pantothenic acid. The only published study was open-label with no placebo group, which is a serious problem for a condition where expectation strongly shapes results.

What the science says

  • Hair density and shedding Limited evidence

    An open-label multicentre study in 112 people with light diffuse hair loss reported increased hair density, a higher anagen proportion and 59% less shedding after 12 weeks of a millet extract, pantothenic acid, L-cystine and biotin capsule. There was no placebo group, the comparison was against each subject's own baseline, and the sponsor was involved in the design and the decision to publish.

  • Millet extract alone Limited evidence

    No study has tested millet seed extract on its own. Any effect could equally come from the cystine, biotin or pantothenic acid in the same capsule.

  • Subjective outcomes Limited evidence

    Much of the reported benefit was hairdresser-rated appearance and subject satisfaction. These endpoints are highly susceptible to placebo effects in an unblinded design.

Dosage & safety

Studied doseTwo capsules per day of the combination product used in the study, taken for at least 12 weeks. Individual millet extract doses are not standardised across brands.
SafetyWell tolerated in the published study. Biotin at supplemental doses interferes with several laboratory immunoassays, including troponin and thyroid tests, and can produce dangerously misleading results — tell your doctor if you take it, and stop several days before blood tests. Persistent hair loss deserves a medical workup.
