Sheep placenta extract is used in some cosmetics. Laboratory and early studies have looked at placenta extracts and hair or skin cells, with interesting but limited findings. These are ingredient studies, not proof that any product, including Folli-Fuel, grows hair.
What studies looked at
Some lab studies examined placenta extracts on cultured hair-follicle cells; reviews discuss uses in skin care. Most work is early-stage.
Reading it carefully
Lab results in cells do not always translate to people. We describe the research honestly and do not claim results.
Questions
Is it from humans?
No, Folli-Fuel uses sheep placenta extract.

Studies mentioned
These studies looked at ingredients or general approaches. None of them tested our treatments or products, so they are background, not proof.
