Do Daily Arch Patrol
Give brows a glance each day before applying mascara. If they look like they need a shape-up, pluck no more than three hairs from each side to prevent sparse spots, says Sania Vucetaj, owner of Sania’s Brow Bar in NYC. That’s especially important when tweezing on your dominant side. (For instance, a right hander is prone to attacking her right brow.)
