Everyone’s eyebrow maintenance routine is different, but one way to keep your eyebrows looking great is to give them the occasional trim. Whether your eyebrow makeup arsenal consists of gels, pomades, pens or pencils, you need a groomed base to work with for the best results. Which brings us to our most pressing eyebrow question to date: How do you trim your own eyebrows? In celebration of National Brow Day, which falls on October 2, we tapped brow expert Joey Healy to walk us through the process. If there’s one person you can trust to get you the naturally full and sculpted eyebrows of your dreams, it’s Healy. With a long list of celebrity clients and a brow salon in New York City — not to mention his own set of perfectly groomed eyebrows — it’s safe to say he knows what he’s talking about in this arena. When Healy’s not doing touch-ups himself, he’s empowering people to learn to style their brows at home through his complete collection of eyebrow grooming products.Sure, you’ve probably seen some beauty influencer or makeup artist trim eyebrows before — or maybe you’ve even taken a stab at trimming your own brows — but do you really know the best technique to get the job done? Ahead, Healy walks us through the best way to cut your eyebrows, plus mistakes to avoid and the tools you’ll need.
