Laser Hair Removal Information

1960 to 1969 Wave 1 lasers
The first lasers used for dermatology in the mid to late 1960's emitted a continuous wave, but this was not practical for hair removal, since the beam could not be controlled well enough to avoid collateral skin damage. The development of the Q-switch (similar to a camera shutter) allowed laser energy to be emitted in controlled pulses.

1969 to present: Wave 2 lasers
Early laser-like devices (see photoepilators) selectively targeted individual follicles by delivering energy through a wire-thin fiberoptic probe (and later through a penlight-type device). This device was rushed to market without adequate testing of effectiveness. It was marketed illegally as painless and permanent until FDA stepped in. These devices turned out to be tedious to use, logistically difficult to maintain the probes, and ineffective for permanent hair removal.

1979 to present
Wave 3 lasers:
As with electrolysis, the early published clinical data on laser hair removal involved the successful treatment of ingrown eyelashes. [1] This led to research and even a commercial attempt at a device using an argon laser for general market hair removal. This device was rushed to market without adequate testing of effectiveness, and it turned out to be tedious to use and ineffective for permanent hair removal.

Other researchers began using lasers for dermatological procedures and found them useful for removing some kinds of tattoos and for the treatment of some kinds of vascular lesions. In some instances, it was observed that hair loss occurred in treated areas, which led to experiments in epilation in animal models and later human subjects in the early 1990's.
