Although there still is debate about the ultimate results of laser hair removal, (that is, its ability to produce permanent reduction without future regrowth), it has several distinct advantages over electrolysis, including faster treatment and reduced pain.
These authors compared the effectiveness of electrolysis and long-pulsed alexandrite laser therapy in removing 24 areas of unwanted axillary hair in 12 patients. Electrolysis was performed at a current of 4-8 mA 4 different times at 3-week intervals on the patients' right axillar areas, and the laser at an energy of 30-50…
