This is what we call a soft seagull arched shaped brow. It's curved slightly which softens the style. The brows have an ombre effect underneath the brow and a crisp defined line on top. You can see the brows have been trimmed to create this clean line and brushed up into place along the tails.
Create the look with a brow threading and brow trim, removing very little underneath the brows and creating a clean line along the tops with a brow trim. Use a brow soap to style and set into place. Apply a brow powder and create an ombre effect by using less or no brow powder on the bulbs or along the bottom outline of the brows. Apply in layers until you get the desired effect.
