I have had several laser hair removal treatments, 12 to the chin and neck, 1 so far on my mustash, and 5 on my legs, underarms, and brazilian bikini.
I have to say that although it took longer than the prescribed "6 treatments" to remove the hair from my chin and neck, I do see a marked improvement. I had hoped to be completely hair free. The few hairs remaining are lighter in color and texture and not nearly as embarressing as they once were. I would say the reduction is about 85% which is pretty good.
I have had the best results on my underarms and legs, I still have a couple of treatments to go, but as of treatment number five I can get away with shaving only once a week and the hairs that do grow back are much lighter. I used to have to shave everyday!
My bikini area is coming along... probably about a 50% reduction in five treatments and it's too soon to really discuss the mustash.
Overall I recommend it, but I warn those expecting too much that your hair reduction may not be 100%. Laser hair removal is great if you can live with the fact that you may see a marked reduction but my not be completely bald in your treatment areas once all is said an done.
