With the development of laser technology, the effect of laser-assisted hair removal has been greatly improved, and now more about physiology of hair and interaction between laser and tissue are understood. Using long-pulsed and long-wavelength laser technology with cooling system, laser assisted hair removal on dark-skinned patients become safer and more effective today. The most frequently used light sources for hair removal on dark-skinned patients include the long-pulsed alexandrite (755 nm), long-pulsed diode (800 nm), long-pulsed Nd:YAG (1 064 nm), and intense pulsed light (590-1200 nm). The long-pulsed Nd:YAG laser represents the safest device for hair removal on dark-skinned patients because of its long wavelength, although the alexandrite laser, diode laser,and intense pulse light may be used.
