Here are some tips that will help you decide your face shape.
Round Face: Your face is nearly as wide as it is long and your cheeks are the widest part of your face.
Oval Face: You have very defined cheekbones and your forehead is wider than your chin.
Heart Face: Similar to an oval shape, but you have a wider forehead and a less prominent chin.
Long Face: Your cheekbones, forehead, and jaw are the same width, and you have a defined chin.
Creating Perfect Eyebrow Shapes
Now that you have decided your face shape, follow these guidelines.
Round Face: If you have a round face, you'll want to tone down the curviness by creating a high arch in your brow. This will draw the eye up and down, creating the illusion of a longer face shape.
Oval Face: As a makeup artists, I enjoy playing with eyebrows in this instance because this is the preferred face shape. While you're safe to experiment, a soft angled style is your best bet.
Heart Face: Creating perfect eyebrow shapes can do wonders for your look. In this case, you'll want to use your brows to help minimize sharp angles in your face. Create curves with a rounded brow. This will give a softer more feminine appearance to the face.
Long Face: If your face is long, you'll want to style your eyebrows so that your face appears shorter. You can do that with a flatter brow shape. The horizontal shape will keep the eye moving across and not up and down.
At-Home Maintenance
After you've seen a professional, you should be able to maintain your arches by following basic beauty tips at home. Follow the original shape and tweez the few stray hairs that grow in. As a rule of thumb, you should visit your brow stylist every four weeks.
