I guess no one wanted to go out on a limb here.
No one can really say what your results will be. There are just too many variables.
LASER is given the right to call itself "Long Term Hair Reduction" by the US FDA, because it could not prove itself being capable of delivering anything that could be termed Full Permanent Hair Removal with any certainty. In fact, the studies used to even get that clearance don't even go far enough to show a conclusion, they only go far enough to show a change, and then POSTULATE that continued treatment would show a continued change. So the science side is that no reliable study has shown anything that could be called Permanent Hair Removal, and the FDA was not even satisfied that they had shown Permanent Hair Reduction. The studies could only justify, after lots of brokered discussion the new term "Long Term Hair Reduction". Will the term of your reduction be something you feel worth the price? I guess you have to pay your money and take your chances.
There are no studies to say that LASER or Electrolysis for that matter, are safe when used on the genital area, however, Electrolysis has been used in that area for almost 150 years with no recored problems or side effects.
