Waxing does the exact opposite. Since you're removing the entire hair, from root to end, the hair disappears until it regrows the bulb underneath the skin and then grows out of the skin. Older women who've been plucking their eyebrows for years usually don't have much maintenence to do anymore since after a while the hairs usually stop growing after being ripped out so many times.

The whole grows back thicker and darker thing is a total myth by the way...even for shaving. Not true!
