Q: How do you use a brow brush?
A: Short, light strokes following the direction the hair grows, filling the sparse areas rather than drawing an outline. Start at the arch and work outward, then fill the front last with the least product.
Q: What is a spoolie used for?
A: Brushing brow hairs into place and softening product afterwards. Running a spoolie through at the end is what stops filled brows looking drawn on.
Q: Which brush is best for brows?
A: A firm, angled brush for filling and a spoolie for blending. The angle lets you make hair-like strokes rather than a solid block of colour.
