Q: How does laser therapy work?
A: The actual mechanism by which Low Level Laser Therapy (LLLT) stimulates hair growth (i.e., increases the anagen phase of the hair cycle) is still unknown. Possible mechanisms include the following:
- Stimulating the production of various growth factors (insulin-GF, vascular endothelial-GF, fibroblast-GF)
- Dilating the blood vessels of the hair follicles
- Increasing the production of ATP (molecular energy) in the cells through its effects on mitochondria.
