Biomagnetic fields refer to the magnetic fields generated by biological organisms, including humans, due to the electrical activity of cells, particularly in the nervous and muscular systems. In the context of hair loss, research has explored the potential influence of these fields on hair follicle activity and regeneration, suggesting that they may play a role in cellular signaling and growth processes. Key distinguishing characteristics of biomagnetic fields include their low intensity compared to external magnetic fields and their potential to interact with biological tissues, which may have implications for therapeutic approaches in treating hair loss.
