Thanks for the post, Corvaith-- good report.
As far as waxing brows at home, this is VERY hard to do. If tiy have a monobrow or something, a little wax to get most of the stragglers might be OK, but for any hairs that are near the ones you want to keep, you’re better off plucking. Even one or two hairs can make a big difference in how your brows look, so it’s better to fine tune things one hair at a time.
