Stimulates Hair Growth

Rosemary oil is to promote hair growth, though there is not much scientific evidence to prove this. However, a recent study on lab mouse showed that topical administration of rosemary leaf extract (RO-ext, 2mg/day/mouse) improved hair re-growth in mice that experienced hair re-growth interruption induced by testosterone treatment, suggesting an anti-androgenic activity mechanism of rosemary extract. The study published in the journal Phytotherapy Research concluded that rosemary extract is a promising crude drug for hair growth.
