These hair laser treatments use light therapy or phototherapy to apply light energy to your scalp. This light energy produces a therapeutic result through a completely natural photobiochemical reaction. Laser and LED (light emitting diodes) are commonly used light sources so you can enter into one of these procedures with complete confidence. The low level lasers that are used in these procedures serve to energize the tissues that make up your scalp’s surface. By providing this highly controlled form of energy for your scalp, your scalp’s cells use the energy to restart normal chemical processes that were for one reason or another not working before. The energy that is created by the LED light and delivered to your scalp vastly improves your scalp’s cellular metabolism, which has been highly successful at accelerating the repairing and rejuvenation of previously damaged skin cells.
