First things first – do you even need to fill in your eyebrows? If your brows are already naturally dark, the same color as your hair, and reasonably thick, filling them in is completely unnecessary. You should be fine as long as you give your shape regular maintenance to upkeep the shape. Adding any product to them can cause them to look comical. If you have sparse, thin, or light brows, or your brows don’t match your hair color, that’s where you should consider filling them in.
Brow powder is excellent for people whose brows are very light, but don’t need much definition. It’s easily applied and blended through the brow with an angled brush, and will enhance the color and strengthen the appearance of a weak brow. If your brows are thin or sparse, stay away from powder, as it will create an unreal mess.
Brow pencil is the remedy for anyone with thin or sparse brows. It’s a thicker formula and allows for the most precise application, and affords wonderful staying power. To mimic the appearance of natural hairs, short, light strokes can be used. If you’d like, you can use an angled brush to better distribute and blend the product through the brow.
Brow gels are best for someone whose brows do not match their hair color. The opacity you’ll get from a brow gel will recolor the hair, versus just filling it in, and is much more practical than dyeing the brow. If you have thin or sparse brows, gel isn’t going to do much for you. Instead, switch up the shade of your pencil to a more harmonious shade.
Even if your hair is a natural red shade, never fill the brow in with a red pencil. It will look artificial and fade to pink or orange over the day. Always use a color in the brown family that’s approximately two shades lighter than your hair color, as matching your hair color exactly will create a very strong and bold eyebrow effect that will distract from your makeup.
