TLDR The ingredients may help prevent hair loss and aging by boosting hair growth signals and reducing stress and hormone effects.

The study explored the effects of a complex of nanoencapsulated active ingredients (AcPi) and its cosmetic formulations (ShPi and HtPi) on hair loss and follicular aging. The research involved treating human hair follicle dermal papilla cells and human scalp cultures with these ingredients, followed by exposure to UV radiation or testosterone. Results indicated that AcPi prevented oxidative stress and balanced mitochondrial activity, enriched the WNT/β-catenin signaling pathway to stimulate hair growth, and extended the anagen phase of the hair cycle. ShPi and HtPi minimized degradation of COL17A1 and controlled androgenic metabolism by reducing DHT production. Although the full effects of AcPi were not completely understood, the findings suggested it could prevent follicular aging and hair loss through mechanisms involving energetic homeostasis, antioxidant, and anti-androgenic actions.
