Picture of Low Level Light Therapy: Laser Comb
Low level light laser therapy (LLLT) has been used to treat a variety of medical disorders from ulcers to musculoskeletal disorders. In 2007, a low level light device was approved by the U.S. Food and Drug Administration (FDA) to treat male pattern hair loss.
The laser comb is a handheld device that was approved as a device which has a different standard for FDA approval than a medication. The device is sold over the counter without physician prescription or physician monitoring.
