When you have an injury, your body needs cells (like fibroblasts) to migrate from healthy areas to the damaged site
Compared to classical gastroprotective peptides such as sucralfate or proton pump inhibitors (PPIs), it acts via a completely different pathway: restoration of mucosal microcirculation rather than acid reduction or formation of a mechanical protective layer
For a comprehensive review of these mechanisms, a peer-reviewed study in Cell and Tissue Research documenting the role of gastric pentadecapeptide BPC-157 in accelerating musculoskeletal soft tissue healing lays out the signaling cascade in detail
While not hair-specific, their systemic regenerative effects may support overall follicle health, particularly following scalp trauma or procedures
Salutary effect of gastric pentadecapeptide BPC 157 in two different stress urinary incontinence models in female rats
Wnt also regulates beta-catenin, which is essentially the switch that tells follicles to grow rather than rest
