In controlled clinical trials, LLLT was found to stimulate hair growth in both men and women. The main mechanism suggested was epidermal stem cell stimulation in the bulge, and moving of the follicles into anagen phase.

One author disclosed to related industries and disclosed being an expert witness for Advanced Hair Studio.
