First of all, you should note that everyone has a certain face structure. Secondly, we have different brow shapes (flat, arched, curvy). Also, know the type of brow shape that works for you, because wearing make-up, or being a make-up artiste is similar to being a painter, only this time, your canvas is the human face. You have to be able to visualize it in your mind and then put it down.
The lesson for today is to study your face and visualize in your minds the eye brow that would work best for it. An easier way to do this is to pick up a piece of paper and a pen, look in the mirror, try sketching what you see in reference to your facial structure, then you fit in different brow shapes into it and see which one catches you eye best.
Here are some essential guidelines to achieving this:
1: For shorter faces, a longer brow would suite you better and give your face the illusion of length.
2: For longer faces, it would do you good to make the brows slightly short to avoid your face from looking like its going on forever.
3: For rounder faces, a bit of arch would do you a world of good to make that face appear more oval.
4: For oval faces, a soft and somewhat flat arch would suite you better.
5: For square faces, avoid the arch because it could give your face the wrong dimensions. A curvy brow would look better on you.
