Fuller, fluffy-looking brows with natural definition and serious staying power.

About this shade
A neutral brown. A balanced, medium brown with a neutral undertone. Complements light-to-medium brown brow hair and works across a wide range of complexions.
How to use

1. Brush brows up and out with a spoolie.
2. Start at the inner corner. Use light, flicking motions to draw hair-like strokes in the direction your brows grow.
3. Build shape and fullness toward the tail. Keep it soft. Keep it believable.
