- DENTIFY Get to know your brows Start by determining key areas before going in with the pencil. BRUSH UP Reveal your fullest shape Brush brows up with the spoolie to show any gaps. FILL Shade any sparse spots Flip to the pencil side and lightly fill in gaps using short, feathery strokes to mimic the look of brow hairs. REFINE Add extra definition Trace the outside of brows and bottom edges of arches for a more structured look. Comb through with the spoolie to blend and pull color through.
