What makes the best laser hair removal?

Despite having read many articles on what is considered the best laser hair removal technique, all I seem to have gathered is that I am more perplexed than ever. It is evident from the various articles published in magazines on which is the best laser hair removal procedure, but then they fail to tell you exactly why such a claim holds true. Then, what does make the best laser hair removal technique? Whether it be the type of laser technology being used (Diode, Alexandrite, Nd:YAG); technician proficiency; number of treatments; or does the best laser hair removal treatment actually lie in one's own personal condition?
