What are hair follicle stem cells?
Hair follicle stem cells are undifferentiated cells located in the bulge region of the follicle that play a vital role in regenerating hair during each new growth cycle.
They activate in response to biological signals and environmental stimuli, triggering the production of new hair shafts and supporting follicle renewal. Damage to these cells can lead to permanent hair loss.
Studies suggest that red light therapy may activate these stem cells by increasing mitochondrial activity, potentially aiding in the restoration of natural hair growth mechanisms.
