Laser hair removal is a form of permanent hair removal procedure, it uses a single wavelength with specific energy to destroy the hair root.
In the market, there are 4 types of laser hair removal system available. They are:
1) Ruby laser with wavelength at 694 nm, e.g RubyStar and Palomar E2000.
2) Alexandrite laser with wavelength at 755 nm, e,g GentleLASE, Apogee, and EpiTouch Plus.
3) Diode laser with wavelenght at 800 nm, e.g Lumunes Lightsheer, SLP 1000, F1 Diode, MeDioStar, LaserLite, Epistar and Apex 800.
4) Nd:yag laser with wavelenght at 1064 nm, e.g Cutera CoolGlide, Medlite IV, Varia, Athos and Lyra.
