Once you’ve established your true brow shape and cleaned it up accordingly—tweezing one hair at a time to protect against over-plucking—you can embolden your brows with makeup. Most experts recommend filling in eyebrows with a combination of powder and pencil—especially if, despite growing your arches out, they remain thinner than you’d like. “If you’re lacking hair in your brows, applying powder over a waxy pencil will make the color stick,” explains Soare, who shapes the hairs above Megan Fox’s come-hither stare.

When choosing a pencil and powder, Nelson says it’s important to go with a neutral tone that’s not too red or yellow. “Blonds should look for taupes, darker blonds and brunettes should opt for ashy browns, and dark brunettes should pick cool dark browns,” he says, adding that redheads and those with jet-black hair should reach for chestnut and blackened brown cosmetic shades, respectively.
