Fuller thin eyebrows
Use a brow pencil. Choose one that is a shade or two lighter than your natural brow color– it doesn’t have to match exactly but don’t go any darker. Then sharpen the pencil until it’s really sharp and carefully fill in any spaces. To keep your new brows from looking too drawn-in, take a tissue and gently rub it along the shape of your brows. It will instantly look more natural.
Fill up hair-less brow ends
Use brow powder to fill in less-hair part and follow or create shape. Don’t try to create shape with the shadow, just follow the natural one. That will help to extend the brow in a natural way.
