Photomedicine for Hair Regrowth is well known, however recent research suggests much higher doses are needed to maximize the hair regrowth effect  – e.g., >=20J/cm2 compared with 4J/cm2 past target; see “Various Wavelengths of Light-Emitting Diode Light Regulate the Proliferation of Human Dermal Papilla Cells and Hair Follicles via Wnt/β-Catenin and the Extracellular Signal-Regulated Kinase Pathways” , Ann Dermatol. 2017 Dec; 29(6): 747–754. Published online 2017 Oct 30. doi: 10.5021/ad.2017.29.6.747 .

In light of this research, the figure shows where some common photomed devices for hair regrowth may lie on the revised dose-response curve:
