What's best for thinning brows: pencil, powder, or gel?

—Marisa Nalevanko, Washington, DC

Bobbi: The simplest, most natural-looking fix is a matte powder eye shadow in a shade that matches your brow hair—not the hair on your head. Once you’ve found that, dip a stiff, angled eyeliner brush in the powder, tap off the excess and use it to sketch over areas that look thin. Then use a clear mascara or brow gel (like Maybelline Great Lash Clear Mascara; $6; drugstore.com) to brush the hairs up and out. That neatens the brow and seals in the powder.
