When using a pencil to fill in and shape your eyebrows, use a sharpened pencil so that you have a fine tip to work with. You want to draw in short lines to mimic natural eyebrow hairs. Avoid drawing one continuous line for the entire length of the eyebrow, as this will look very unnatural.
Begin with the thickest part of the eyebrow, working towards the arch, and continue lightly toward the tail of the eyebrow.
Draw in the hairs, using short, quick flicks. Do not brush through afterward as doing so will smudge your clean, precise lines.
If you are pleased with the shape, and the amount that you have applied, you can choose to gently brush through a brow gel, or clear mascara, to set the eyebrows.
Complete the other eyebrow to create balance and make them look symmetrical. Especially important when using a pencil to enhance eyebrows – practice drawing short strokes to mimic real hair strokes on the back of your hand, till you get it down. Change the pressure and angle of the strokes to see which looks most natural for your eyebrows.
