I barely pluck my eyebrows (by barely, I mean I pluck a maximum of four hairs every six months). They're pretty low-maintenance, but I do like to fill in the sparse areas. Martin said I was having trouble perfecting my brows because the brush I was using was too flimsy, which meant I was applying the product in places I didn't want because I didn't have much control over where the product was going. As it turns out, I even had a better eyebrow brush in my makeup bag that I forgot was there. Martin instructed me to use the Morphe E29 Angled Brown and Spoolie brush (£4.50), which makes it supereasy to draw on brushlike strokes exactly where they need to be and nowhere else. Easy!
