Laser-assisted hair removal has been reported previously with the Nd:YAG laser, the long-pulse ruby laser, the long-pulse Alexandrite laser, and the short-pulse Alexandrite laser. Results with all these lasers have been successful; however, it has been postulated that the long-pulse Alexandrite laser would have a lower complication rate and greater efficacy at identical fluences than the short-pulse Alexandrite laser. The authors chose to compare directly the pulsed Alexandrite lasers for speed of application, complications, and results. Eighteen patients who desired hair removal were entered into the study. There were 10 female and 8 male patients, with a mean age of 36 years. All skin types from Fitzpatrick classes I through VI were treated. The body areas treated consisted of the face, ears, neck, back, arms, upper thighs, bikini lines, legs, and breasts. One side of the body was treated with the short-pulse (2-msec) Alexandrite laser (Sharplan Epitouch 5100). The other half was treated with a long-pulse (20-msec) Alexandrite laser. Both lasers were set at the same fluence for each patient. Patients reported a 60% to 80% reduction in hair growth at 6 months. Both sides were identical with regard to return of hair growth and complications such as hypopigmentation. Both the long- and short-pulse Alexandrite laser systems yielded an effective method of hair reduction with minimal complications. Equal results and complications were obtained with the two systems. The only exception was that the length of the procedure was shorter with the short-pulse Alexandrite laser.
