Vita Hair Nano Serum

A 2020 laboratory study used a root extract prepared with 50% aqueous ethanol. Researchers measured cell viability and follicle-cycle stages in cultured human cells and isolated follicles.

This was not a trial of people applying Nano. The study extract and concentration have not been matched to this serum.

A 2009 study investigated a methanol extract of the whole plant, published under the name Eclipta alba, in mice. Researchers examined skin changes, follicle counts and markers associated with follicle-cycle stages.

Mouse findings do not establish human results. Nano's extract preparation and concentration are not matched to that study.

A 2001 chemical study identified secoiridoid glucosides in Ligustrum lucidum fruits. This describes constituents of the plant, rather than testing this serum in people.

Fruit research is not automatically evidence for Nano's seed extract. Direct human hair evidence matching the exact seed extract remains unverified.

A 2015 study examined red ginseng extract and selected ginsenosides in cultured human hair follicles and follicle cells. Researchers measured cell proliferation and signalling activity.

Human tissue in a laboratory is not a human treatment trial. Nano's root extract has not been shown to match the studied red ginseng preparation or ginsenoside levels.

A 2017 study tested a different 0.2% caffeine-based liquid in 210 men over six months. Its primary endpoint was the proportion of hairs in their growth phase. The study was open-label, sponsor-funded and had no placebo arm.

It did not test Vita Hair Nano Serum. Nano's caffeine concentration, delivered dose and formulation match are unverified, so its results cannot be claimed for this bottle.
