June 2015 in “Lasers in Medical Science” This study found that low-level laser therapy with an 830-nm wavelength most significantly stimulated hair growth in rats, compared to other wavelengths tested.
February 2025 in “Journal of Biophotonics” This study found that using dual-wavelength low-level laser therapy is more effective for hair regrowth in mice than single-wavelength treatment and significantly better than no treatment, based on 14 days of phototherapy with LED lights.
