What is cytochrome c oxidase (CCO)?
Cytochrome c oxidase (CCO) is a vital enzyme in the mitochondrial respiratory chain that drives ATP production.
CCO acts as the final electron acceptor during cellular respiration, directly impacting a cell’s energy output. Red light wavelengths, particularly 650 nm wavelengths, have been shown to stimulate CCO activity, making it central to Photobiomodulation (PBMT) effects.
By enhancing CCO activity in scalp tissues, red light therapy can help increase ATP production in hair follicle cells, improving the cellular environment for hair regrowth and follicle vitality.

Vasodilation
Mechanisms of Action
Vasodilation is the widening of blood vessels, resulting in increased blood flow to tissues.
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.
