My sister was raving about threading, so I decided to try it recently on my brows. I love it!
Before that, I would get them waxed and tweeze the few straw brow in between waxings. But, many people that wax brows (as Summerchild said--at one point I too was hooking up my own brows) want to wax them in a straight line, and/or wax them too thin. Tweezing never hurt me in the past, so I new threading wouldn't hurt much eaither (actually, waxing hurts for me more--go figure). Now I get my brows threaded every two weeks. I like them b/c she never does them too thin.
As for other body hair, I shave using my Venus razor ( idon't have too much body hair)...
