Laser hair removal consists of using laser and light-based sources to remove the entire hair (called epilation). Xenon flash lamps are used to create Intense Pulsed Light (IPL), which is capable of full extraction as opposed to procedures such as shaving, which only remove hair above the surface of the skin (called depilation). If you have unwanted gray hairs, and you want to stave them off before your head becomes a virtual forest, laser hair removal is the way to go.
