Eyebrows are very important because they help shape the eyes. Here is a handy tip: Line up the inside of the eye with your nostril. This is where your eyebrow should begin, then line up the outside of your eye with your nostril and this is where your eyebrow should end. The arch of your brow should be the centre of your eyeball. This should give you the perfect brow shape. Fill in any gaps in the brow using a very soft eyebrow pencil (matching the colour to your brows and hair) using very small strokes which can then be ‘brushed in’ for a natural professional look.
