Laser and flash-lamp technology now offers the potential for rapid, safe, and effective treatment of unwanted hair. An ever-increasing number of published studies have confirmed the long-term efficacy of laser and flash-lamp treatment. The benefits of this technology have largely been limited to individuals with dark hair and relatively fair skin. The first studies using devices with a combination of longer wavelengths, longer pulse durations, and adequate epidermal cooling have shown that it is possible to safely and effectively treat individuals with darker skin types. The remaining challenge is to develop the means to eliminate light-colored hair as well. The increasing consumer demand for low-cost hair removal has driven the development of low-cost hair removal devices, such as small, pulsed flash lamps. The rapid pace of technologic advances and continued studies of hair follicle biology promise to improve this field over the years to come. In the future, small, low-cost laser-razors may replace all other means of hair removal.
