Pharmactive spotlights the Kyoh® nutricosmetic ingredient
References: nutraceuticalbusinessreview
Pharmactive has introduced a new oral nutricosmetic ingredient named Kyoh®, which is designed to support hair growth and follicle function through a naturally derived botanical extract.
Kyoh® is a pure, standardized formulation sourced from rocket leaves, also known as Eruca sativa — a common salad green that has been traditionally used in South Asia as a hair tonic. The oral nutricosmetic ingredient works from within the body by leveraging a specific group of flavanol-rich compounds, trademarked as Erucosides®, which include quercetin, kaempferol, and isorhamnetin.
Preclinical laboratory studies have shown that the Kyoh® extract can influence several cellular mechanisms relevant to hair health, such as activating vascular endothelial growth factor to improve blood supply to the scalp, stimulating fibroblast growth factor 7 for keratin production, and upregulating the antioxidant regulator NRF2 to protect follicle cells from oxidative stress.
