LA is a big place - any general geographic location?
I got mine done at pure touch laser center on woodman avenue in studio city. I found them via a groupon coupon and they were pretty cheap and they use a very good laser. I had about 12 sessions and now only a few straggling black hairs have popped back up after my last session 6 months ago. A couple of touch up sessions ought to take care of them. I went in guy mode for the first few sessions and finished in girl mode and no one ever said anything.
