For hair growth, the relevant signaling pathways are: vascular stimulation (more blood flow to the dermal papilla), follicle repair (extending the anagen growth phase), inflammation modulation (calming the chronic low-grade inflammation that contributes to follicular miniaturization), and systemic growth signaling (IGF-1 levels that influence overall regenerative capacity)
The injections help restore vitamin B12 levels quickly in those with deficiency, allowing the body to properly utilize fats and carbohydrates for energy, produce new proteins, and maintain healthy blood cells and nerve function
