If you've never used Nair before, try a little patch on your leg first. If you have sensitive skin you probably won't want it anywhere above your knees. I have pretty sensitive skin myself, and I've never been able to use it above my knees without it itching and burning like crazy. Even below my knees it can get kind of irritating!

As far as shaved or not...some like it, some don't. I've never fully shaved the area, probably never will. I keep it trimmed though, and that seems to work just fine. =)
