Hi,
I have had laser hair removal done on my armpits, it was $29CDN a session, I did 7 sessions in total, each spaced 6 weeks apart, and now I dont ever have to shave my armpits. Best investment ever!! It works best on darker hair, will take away the visable hair, but will still leave behind the very fine, light baby fuzz hair. As far as pain goes, it kind of felt like being snapped with a tiny little elastic band, and I never took any kind of pain cream. I definitely plan on getting more done! I found the most dramatic results were after the first session, but it takes a few weeks to notice that the hair hasnt grown back. Hope this helps
