What are photoreceptors?
Photoreceptors are specialized molecules or proteins that detect and respond to light energy.
In Photobiomodulation (PBMT), photoreceptors such as cytochrome c oxidase (CCO) absorb light photons, triggering cellular responses that boost energy production and tissue repair.
Targeting photoreceptors in scalp tissues allows red light therapy to specifically activate regenerative pathways critical for promoting hair follicle health and growth.
