Bangs sit directly across the forehead — the single fastest way to change a diamond face's apparent length and upper-face width without committing to a full haircut change. A diamond face narrows at both the forehead and the jaw while flaring dramatically at the cheekbones — the opposite structure of a rectangle. The chin is often pointed, and the temples can appear slightly recessed relative to the cheekbone's width.
Which Fringe Shape Fits
Which fringe shape fits: Given that this face's forehead reads as "narrow, often the narrowest of the three width measurements," the fringe shape that serves soften and add visual width at the forehead and jaw to bring them closer to the cheekbone's width, while avoiding extra volume directly at cheekbone height, which is already the face's widest point is the one worth requesting — a straight, blunt fringe shortens a long forehead and adds horizontal weight; a soft, side-swept or curtain fringe narrows a wide forehead without fully covering it; wispy, textured fringe adds movement without much line at all.
Where to Be Careful
Where to be careful: Slicked-back styles with no fringe that leave the narrow forehead fully exposed, and frames sitting exactly at cheekbone width, which visually extends the widest point instead of balancing it.
