Introduction
Hair loss affects both women and men. Light technologies such as LED and laser are now at the heart of modern hair solutions. But what is the real difference? And more importantly, which one is the most studied?
LED: Diffuse light
LED devices emit broad, non-coherent light. shallow penetration - limited stimulation - variable efficacy - often cheaper
LEDs can improve superficial circulation, but their impact on deep follicles remains limited.
LLLT 650 nm Laser: Coherent light
LLLT (Low Level Laser Therapy) technology uses coherent, concentrated red light and has been studied for over 20 years. deeper penetration - studied photobiomodulation - mitochondrial stimulation - higher potential results
Photobiomodulation: the science behind LLLT
The 650 nm red light acts on the mitochondria, the cells' "batteries". It can: support cellular energy - promote microcirculation - reduce oxidative stress - create an environment conducive to hair growth
