is it true?please help

I’m currently using the ND Yag laser hair removal and i’m really happy with the result so far on my legs and bikini area…im on my 5th treatment… I just decided to surf the net and read on few of the articles that the YAG laser is not that effective LONG TERM…that a complete regrowth of all of the hair is seen 6 months after the treatment…How true is that? Anybody here that has been on the YAG and had a very satisfying long term result?..I mean, I know laser doesn’t really take out all 100% of the hair, but at least a good considerable amount will be great…now i’m getting worried that all of these treatments will just go to waste…Any info guys?thanks
