Nair is awful. I used it a couple of times for bikini area and it was better than shaving, cuz shaving gives me horrible painful bumps. But it stinks, stings, and sometimes makes me itch. Just the other day I thought I'd try it on my legs. Never again. My legs burned really bad and itched for a couple of days, and they were soooo red. And Nair doesn't work all that well on my hair anyway, doesn't get all the hairs.
Makes me break out. Can't use it. Plus shaving isn't bad, even with nics. Just don't accidently tear off a two inch strip that's an inch wide. You'll bleed for a very long time.
