I'm a little late to this thread, but I had laser hair removal done "Brazilian style" (meaning, all the hair was treated, like getting a brazilian wax.) I chose to get the Brazilian instead of the regular bikini because my hair down there was so thick. I wanted it all gone, or at least lessened! From the very beginning the treatment center was very clear that it would not leave me completely hairless - I could only expect "Permanent Hair Reduction." This was fine with me, as anything would be an improvement. Shaving it usually resulted in half a day of smoothness followed by a week of angry red bumps. I was considered to be the ideal candidate (fair skinned with dark hair.) I won't lie, the treatments were painful, but no worse than getting waxed. If you have had a bikini wax and managed not to cry, you will be fine with lasers. :) They were not able to get "all" of the hair down there because of my pain tolerance... there are some parts that just should not be touched by a laser. But anything visible under a skimpy bikini was taken care of easily. It has now been a year since I finished treatment and I am still pleased. I purchased the unlimited treatment plan, and I'm happy I did. I needed more than the average number of treatments until I was satisfied with the amount of hair. It was nice not to have to pay extra for that. I still have hair down there, but it is soft and fine, grows back slowly, and very easy to shave. It takes less than 30 seconds in the shower to shave my bikini area, which makes beach season awesome. I recommend it for that reason - it doesn't make shaving obsolete, but it does make it a lot easier.
One thing to be wary of is the sun. You need to avoid sun exposure to the treatment area for the entire course of treatment. It's a good thing to do in the fall/winter for that reason. Be careful of Groupons for laser hair removal. After my great experience getting my bikini area done at full price, I bought a Groupon for 8 treatments for the underarms at a different med spa. The results there were not nearly as good, and they were also a lot less painful, which seemed to be revealing. I suspect they were not using a high powered laser in an effort to get me to buy more treatments at the non-Groupon price. I definitely still have to shave my armpits every other day!
Also, be sure to go to a facility where there will be a doctor handling the treatments. The laws vary state to state, but I got my lasering done in NJ (where a doctor is required to be on the premises, and in the case of the first place I went, actually operated the laser at all times.) It's a serious burn hazard if not operated correctly. Meanwhile, just over the border in NY, the equivalent of a nail tech license is enough to operate a laser. No thanks!
