Background and Objectives There are a variety of different laser hair removal systems currently available. There are also systems with identical emitted wavelengths; yet their emitted pulse durations vary. There are few data comparing these systems in an objective manner. Study Design/Materials and Methods Fourteen subjects received three treatments with two different pulse duration 755‐nm alexandrite lasers. Paired anatomic sites were treated three times with both a 2‐msec and a 10‐msec system. Subjects were evaluated prior to laser treatment and 6 months after the three treatments with manual hair counts and incidence of complications. Results The average percentage of hair reduction was 33.1% for the 2‐msec‐pulse duration and 33.9% for the 10‐msec‐pulse duration alexandrite laser. No cutaneous pigmentary changes or scarring was noted 6 months after the final treatment. Conclusion The alexandrite laser is effective in removing unwanted hair. There was no difference in response between a 2‐msec and a 10‐msec alexandrite laser. Lasers Surg. Med. 25:223–228, 1999. © 1999 Wiley‐Liss, Inc.
