1) Squared-off inner corners are a major #browgoal right now. New York City eyebrow guru Elke Von Freudenberg calls this the "flat brow," and it's created when the hairs are brushed straight up and trimmed into a clean line. She calls it "the strongest of the bold brows you can do."
2) You should never use a magnifying mirror. "By viewing your brows too close up, you lose perspective on how much hair you've already taken off, " celebrity eyebrow specialist Joey Healy told us.
3) There's a time to go lighter your brow shade a time to go darker. According to makeup artist Brett Freedman it's all about where you want your focal point to be. Smoky eye? Go for a gentler touch with your brow product and use a lighter shade than usual (like he did here on Camilla Belle) to keep your arches from competing with the sultry goodness on your lids.
4) There's a secret to all-day wear. Makeup artist Sir John dropped some knowledge on us in his makeup tutorial with model Karlie Kloss. His tip? Use a pencil and a powder to fill in your brows, so they don't fade as the day goes on.
5) Ombre eyebrows might be for you. Sally Hershberger colorist Corey Powell brightened Michelle Monaghan's brows with a twist—he made them lighter on the outside. Here's why he told us he did it: "It blends with her highlights, brings out the green in her eyes, and really [brings out her features]."
6) Hitting "natural-looking" when filling is all about your hand motion. The folks at Anastasia Beverly Hillsshowed us that small strokes of color in the thickest part of the eyebrow by the nose creates the illusion of more individual hairs. So smart.
7) Keep your skin care products off. "Avoid getting any lotions, gels, sunscreens, foundations, or moisturizers on or around the brow area," says Sania Vucetaj, expert brow tamer and owner of Sania's Brow Bar. "They seep into the brows and prevent growth, or worse, cause the hairs to fall out."
8) Your high point should go here. Shape your brow so your arch is too close to the center of the brow and you could end up looking angry or surprised. Oops. The rule is to keep your arch two-thirds of the way out from the beginning of your brow, Healy told us.
9) It's OK if the full-brow trend isn't your thing.
10) Choosing the right tone for your pencil depends on your hair color. This is not a one-size-fits-all situation. There are totally different rules for blonds, brunettes, and redheads. Luckily, New York City brow specialist Maribeth Madron broke it all down for us.
11) There is a hack for when you find yourself brow-gel-less. If your strands are unruly but there's not a drop of gel in sight, makeup artist Brian Dean shared a quick how-to with us: Mist hairspray a good six to 10 inches away from the bristles of a brow brush, then use it to sweep the hairs from the inner corners to the arch up toward your hairline. Then change the angle to smooth the hairs at the tail end toward the top of your ears.
