In fact, straight hair has been a beloved beauty look for centuries! "I love eyebrow razors! They're perfect for those superfine hairs above the brow and for some into your hairline," she says. "Along with tweezers and scissors, they make a great addition to at-home care to get your best brows." And don't worry, shaving your brows isn't as scary as it sounds.
