LLLT appears safe and effective for the treatment of hair loss in theory and through minimal observational studies, but more clinical and in vitro studies are needed. Proposed in vitro studies may include the effect of LLLT on fibroblast function in controlled settings. Factors such as growth rate and apoptotic rate may be assessed. Similar in vitro studies may be carried out with intact hair follicles. Finally, randomized double blind multicenter trials are needed to truly assess safety and efficacy; one such trial has found promising results thus far.[35] Another study of seven patients did not reveal statistical significance, and proposed that some individuals may be more responsive to this treatment.[36]
