Strong, full brows are infinitely more flattering than overplucked ones. If you've overdone it but don't have any bare patches, brow powder can enhance their shape, says brow expert Anastasia Soare. Take a stiff, slanted powder brush and use small, feathery strokes over the length of your brows. If your brows are really sparse, first fill them in with a pencil "so the powder has something to grab on to," says Soare. The powder and pencil should match or be slightly lighter than your brow color (unless you have very fair blonde hair; then go one shade darker). Brush through your brows afterward with a clean mascara brush to lift away any excess product.
