OCTAPEPTIDE-2.

Valuable CAS - / SKIN CONDITIONING

Octapeptide-2 is a biomimetic peptide engineered to mimic the natural growth factor thymosin β4, primarily recognized for its potent effects on hair vitality. It actively promotes healthy hair growth and mitigates hair loss by stimulating hair follicle stem cells, while also supporting scalp health through collagen synthesis and enhanced microcirculation.

Science

Mechanism of Action

This biomimetic peptide functions by emulating thymosin β4, a critical growth factor. Its primary action involves the activation of dormant hair follicle stem cells, leading to robust hair growth and a significant reduction in hair loss. Furthermore, Octapeptide-2 accelerates cell migration within hair follicles, inhibits programmed cell death (apoptosis), strengthens hair fibers, and imparts a healthy shine. Beyond direct hair benefits, it stimulates fibroblasts to synthesize essential extracellular matrix components such as collagen, elastin, and fibronectin, particularly in the scalp, and enhances local blood flow to deliver vital oxygen and nutrients to hair follicles.
