What is low-level laser therapy (LLLT)?
Low-level laser therapy (LLLT) is a treatment that uses low-intensity lasers or LEDs to stimulate cellular activity without heating tissues.
LLLT operates on the principles of Photobiomodulation (PBMT), using red or near-infrared light to promote mitochondrial function, enhance ATP production, and trigger biological repair processes.
For hair growth applications, LLLT devices target the scalp with specific wavelengths like 650 nm to support hair follicle health, stimulate dormant follicles, and extend the anagen phase of the hair growth cycle.
