For a natural result, always follow the natural line of hair growth. Good make-up should make your eyebrows appear naturally full and structured. Take care when choosing the shade of your pencil, following the natural tone of your eyebrows, and apply each product sparingly and only where you need it. Lastly, remember that your eyebrows should be sisters and not twins. There is no need to make them completely symmetrical and doing so may make you look harsh.
