Quick answers before you dive in.
What is photobiomodulation?
Photobiomodulation describes how specific wavelengths of light interact with cells and tissue. The library includes sources on cellular energy, circulation, dose, and wavelength response.
Why do red and near-infrared wavelengths matter?
Different wavelengths interact with tissue at different depths. Capillus evidence categories include light physics, penetration, 660 nm, 850 nm, and red versus near-infrared research.
What does FDA-cleared mean?
FDA-cleared means a product has been cleared for specific indications. Each Capillus product page uses the specific clearance and indication language associated with that device.
How should I read a research card?
Each card shows the device, source type, the benefit it informs, the title, and a direct link when available. Category-level research is contextual, not product-specific proof.
