Final answer:
The heart-shaped face would require added width at the forehead to achieve a balanced look, as it has a wider forehead and a narrower chin.
Step-by-step explanation:
The facial shape that would require width at the forehead is the heart shape. The heart-shaped face typically has a wider forehead and a narrower chin. To balance the features and give the appearance of an oval face, which is considered the ideal shape, it's important to add width at the forehead. This can be achieved through various hair styles, such as fringes or bangs, and appropriate makeup techniques to highlight and contour the face accordingly.
