The answer to this question is more complicated than one would at first think.
There is not a single “best” laser for hair removal on all patients. The list of machines available for laser hair removal includes the diode, ruby, alexandrite, and Nd:YAG laser, as well as intense pulsed light devices. Many different variations of these lasers are available from numerous manufacturers.
The best laser for laser hair removal for each person depends on his or her skin color. In my experience, the diode laser is the most effective laser for removing hair on lighter skin, whereas the Nd:YAG is the safest and best laser for more darkly pigmented skin. I have not found any laser to be particularly effective in permanently reducing very blond or white hair.
