Nature provides each of us with the right brow shape. While brows often need grooming, it's best not to radically alter the natural contour of your eyebrows. Use professional-quality tweezers to remove stray hairs from around your brows and to clean up the area between brows. If you've over-tweezed your brows, try using brow stencils, to fill in and give you new guidelines for regrowth.
