Sandra Bullock's Natural-Looking Brows Natural brows still need a bit of shaping. Bailey suggests seeing a pro to make a shape for you if you're nervous to do it yourself. You can also use a tool like Benefit Brow Map. "After identifying each point (the start, the arch, and the end), fill in the brow using a natural brow filler," he says. "Remove the hairs that fall below the shape you've just created. This will keep you from going too far into the natural brow shape and over over-tweezing."
