Abstract
Hair removal by using an Alexandrite laser emitting energy between 0.2-40 joules per pulse to provide an energy fluence between 15 and 70 joules per centimeter square and having a pulse duration of between 100 microseconds and 10 milliseconds. A scanner may be used to direct the laser beam on the tissue. The skin in the area to be irradiated may be shaved prior to exposure to laser treatment and may be also covered by a protective substance serving as a heat sink.
