The power Grow comb is a breakthrough laser hair loss treatment that promotes the appearance of new hair growth. Using lasers and infrared LED light, the power grow comb helps stimulate hair follicle cells and improve scalp circulation.  In addition, vibration technology helps stimulate blood flow on the scalp and in turn produce fuller, healthier hair growth. The comb itself has teeth that are positioned perfectly to create separation and allow laser LCD to reach the scalps surface and effect the hair follicles directly.
