Device-based treatments cleared by FDA to treat hair loss include low-level laser therapy (LLLT) and Revian Red dual wavelength LED light therapy (PhotonMD). … The red LED set at 660 nm stimulates hair growth via the classic pathway while the 620 nm LED stimulates release of nitric oxide.
Does LED light stimulate hair growth?
The light creates ATP (cellular energy), which strengthens both the cells and the surrounding area creating a perfect scenario for hair growth. Follicles expand, hair gets thicker, and new hairs grow from the now open hair follicles.

Can you overdose on light therapy?
Side effects of light therapy overdose may include agitation, headache, or nausea. Insomnia, particularly initial insomnia, may also be encountered.
How does red light stimulate hair growth?
