I effing hate my eyebrows. I can't 'shape' them because only the little bit closest to the middle is thick enough to be 'shapeable'... after that it's thin but spread out. I 'shape' it and it sort of disappears or looks crooked b/c of the permanent, natural part. Eww. But I have always tweezed them myself. Mom was a beautician in a former life and told me to warm things up and open the pores first with a hot, moist compress. It limits the amount of damage done when plucking. Then, one at a time and *with* the grain or you're going to raise h*ll some more.
A dab of alcohol (*YOW!*) after both tweezing and waxing will prevent infected pores and zits etc...) finish up with a non-greasy antiseptic or lotion like eucerin.
