Pea Sprout Extract
(Pisum Sativum)
The Plant Stem Cell Activator — Stimulating Hair Root Density from the Ground Up
Pea Sprout Extract is a clinically studied plant-based hair active shown to support hair density, follicle activity, and Wnt signaling pathways involved in reactivating the hair growth cycle.
The Ingredient
What Is Pea Sprout Extract?
Pea Sprout Extract targets one of the most important molecular switches in hair biology — the Wnt/β-catenin pathway responsible for reactivating growth-phase follicles.
Pea Sprout Extract is derived from the sprouted seeds of Pisum sativum — the common garden pea. During germination, the plant mobilizes concentrated regenerative compounds required for rapid new growth.
This sprouting phase contains elevated levels of growth factors, amino acids, phytohormone-like compounds, and biologically active fractions associated with tissue regeneration.
When applied to the scalp, these compounds are believed to stimulate regenerative signaling in hair follicle stem cells and dermal papilla cells — the follicle structures responsible for controlling the hair growth cycle.
Research suggests that pea sprout extract stimulates dermal papilla proliferation and activates Wnt/β-catenin signaling pathways, one of the most important molecular systems involved in initiating and maintaining the anagen growth phase.
The extract also contains naturally occurring isoflavones with mild anti-androgenic activity, which may help support follicles affected by DHT-mediated miniaturization.
Unlike many botanical ingredients used primarily for marketing purposes, standardized pea sprout extract has been evaluated in clinical trials demonstrating measurable improvements in hair density and shedding reduction.

Editor's Note
The Wnt/β-catenin signaling pathway targeted by pea sprout extract is one of the most important areas of modern hair loss research. That makes this ingredient far more biologically interesting than a typical botanical extract.
