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.

Androgen Receptors
Mechanisms of Action
Androgen receptors are proteins inside cells that bind to male hormones like testosterone and dihydrotestosterone (DHT), influencing hair follicle behavior and sensitivity.
Dermal Papilla Cells
Mechanisms of Action
Dermal papilla cells are specialized cells located at the base of each hair follicle that regulate hair growth by interacting with surrounding stem cells and signaling molecules.
Vasodilation
Mechanisms of Action
Vasodilation is the widening of blood vessels, resulting in increased blood flow to tissues.
