Comparison with electrolysis
Electrolysis is another hair removal method that has been used for over 135 years. Like newer laser technology used properly and with several treatments, electrolysis can be used to remove 100% of the hair from an area and is effective on hair of all colors, if used at an adequate power level with proper technique. But the treatment is slow and tedious compared with typical newer laser hair removal. More hair may grow in certain areas that are prone to hormone-induced growth (e.g. a woman's chin and neck) based on individual hormone levels or changes therein, and one's genetic predisposition to grow new hair.
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. It is important to note that the type of electrolysis performed in the study was galvanic electrolysis, rather than thermolysis or a blend of the two. Galvanic current requires 30 seconds to more than a minute to release each hair whereas thermolysis or a blend can require much less. This study thus did not test the capability of all forms of modern electrolysis.
