DIY: This 3-Ingredient Serum Is Hollywood's Secret to Thicker Brows

Were you an overzealous plucker as a teen? Leave a kid alone with a pair of tweezers for long enough and they'll start experimenting to look like their favorite mid-aughts celeb—we know from experience (and have the photos to prove how much we've learned since). But some of these bold (read: misguided) beauty adventures leave behind permanent effects in the form of thinned-out brows—or worse, blank spaces. Even if we manage to refrain from waxing, tweezing, and threading for a bit, sometimes the hair just refuses to grow back on its own—even after several months of swearing off all forms of removal. But don't worry, as there are tried-and-true ways to grow thick eyebrows.

But it's not hopeless. According to eye specialist and esthetician Denise Wilson of Sublime Eyes, a walk-in brow bar in Hollywood, there's a solution you can whip up at home—no pricey products, treatments, or professional consultations required.
