What is 660 nm wavelength?
The 660 nm wavelength refers to a specific red light frequency commonly used in therapeutic devices to stimulate biological processes.
This wavelength is highly absorbed by mitochondrial chromophores like cytochrome c oxidase (CCO), making it especially effective for promoting ATP production during Photobiomodulation (PBMT).
In red light therapy for hair restoration, 660 nm wavelengths have demonstrated strong penetration into scalp tissues, supporting hair follicle metabolism and encouraging a shift into active growth phases.
