Kyoh® and a Targeted Approach to Hair Follicle Health
Hair follicle health is becoming an increasingly relevant area within nutricosmetics. As the category evolves, brands are looking beyond broad beauty concepts and moving toward more targeted ingredients with a clearer biological focus. In this context, Pharmactive introduces Kyoh®, an Eruca sativa leaf extract developed for applications related to hair follicle health.
Within this context, introduces Kyoh®, an Eruca sativa leaf extract developed for applications related to hair follicle support. Rather than taking a broad beauty-from-within approach, Kyoh® has been designed around a more specific area of interest: the follicular environment.
A botanical ingredient designed for hair follicle health
Nutricosmetic innovation is increasingly shaped by specificity. Rather than taking a general approach, Kyoh® has been developed around a defined area of interest: the follicular environment.
Rocket is widely known as a food ingredient, but its phytochemical composition has opened new possibilities for research in hair follicle health. Although rocket seed oil has traditionally been associated with hair care practices in some regions, Kyoh® is specifically based on the scientific study of the leaf extract.
Kyoh® has been developed with a defined composition that includes:
- More than 1.5% Erucosides®
- 1.5% to 3.0% flavonol glycosides, quantified by HPLC, including derivatives of quercetin, kaempferol and isorhamnetin
This standardized composition helps ensure consistency and reproducibility, which are highly relevant in formulation development.
What preclinical research has explored
Interest in Kyoh® is linked to its potential interaction with biological pathways associated with hair follicle function.
A study published in Molecules in 2025 evaluated this flavonol-rich extract in laboratory models using human dermal follicle papilla cells. According to the publication, the ingredient showed a stimulating effect on cell growth under laboratory conditions and enhanced the expression of growth factors such as VEGF and FGF7. ndings support continued interest in three relevant areas of investigation:
- Follicular signaling, through markers associated with the follicular microenvironment
- Cell proliferation-related processes, which are relevant to hair fiber formation
- Cellular stress response, including pathways linked to oxidative balance
As preclinical findings, these results contribute mechanistic insight, but they should not be interpreted as clinical outcomes in humans.
Built for transparency and formulation consistency
Kyoh® is positioned as a botanical ingredient with a defined focus and a transparent supply model. Its raw material is sourced from European farmers, and its production aligns with non-GMO standards and non-irradiation practices.
This combination of botanical origin, analytical control and targeted concept makes Kyoh® a relevant option for companies developing next-generation nutricosmetic products in the hair health space.
Meet Kyoh® at Vitafoods Europe 2026
Pharmactive will officially present Kyoh® at Vitafoods Europe (Barcelona, May 5–7, booth 5D28).
This will be an opportunity to share these findings, discuss preliminary data, and explore formulation possibilities for this new approach to hair health.
