What is nitric oxide (NO) release?
Nitric oxide release refers to the production of nitric oxide molecules that help regulate blood flow and cellular communication.
During red light exposure, nitric oxide can be released from intracellular stores, leading to vasodilation and improved microcirculation. This effect complements ATP production and is considered a supportive mechanism in Photobiomodulation (PBMT).
In red light therapy for hair regrowth, enhanced nitric oxide release can improve oxygen and nutrient delivery to scalp tissues, creating a healthier environment for follicles entering the anagen phase.

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.
Reactive oxygen species (ROS)
Mechanisms of Action
Reactive oxygen species (ROS) are unstable molecules containing oxygen that can cause cellular damage at high concentrations.
Vasodilation
Mechanisms of Action
Vasodilation is the widening of blood vessels, resulting in increased blood flow to tissues.
