Electrolysis is another hair removal method that has been used for over 135 years. At this time, it is the only permanent option for very fine and light-colored hair. The FDA currently allows the term "permanent hair removal" for electrolysis only. Unlike laser epilation, electrolysis can be used to remove 100% of the hair from an area and is effective on all hair colors.
A study conducted in 2000 at the ASVAK Laser Center in Ankara, Turkey comparing alexandrite laser and electrolysis for hair removal on 12 patients concluded that laser hair removal was 60 times faster, less painful and more reliable than electrolysis.
Intense pulsed light (IPL) epilators, though technically not containing a laser, use xenon flash lamps that emit full spectrum light. IPL-based methods, sometimes called "phototricholysis" or "photoepilation", are now commonly (but incorrectly) referred to as "laser hair removal".
