Starting the shortest layer at the chin instead of the cheekbones is the simplest change I make on a diamond face, and styling it is just rolling the ends out on a round brush. The shape is narrowest at the forehead and jaw, so hairstyles for a diamond face shape should add width there and leave the cheekbones alone.
1. Chin-Length Bob and Side Bangs
A chin-length bob with side bangs widens a diamond face at both of its narrow points, since the shape is narrowest at the forehead and jaw and widest at the cheekbones, and the best diamond face shape hairstyles add width at each end. The bob brings fullness to the jaw and the side bangs broaden the forehead. I cut it blunt with light internal layers. Fine to medium straight hair carries it well. Dry on a round brush and turn the ends under. Trim every 6–8 weeks.
2. Curtain Bangs Over Long Layers
Curtain bangs widen a narrow forehead and drop toward the cheekbones without covering them. I cut them to part at the center and sit just above the cheekbones, then point-cut long layers from the chin down to build fullness at the jaw. Fine to thick hair, straight or wavy, works. Dry the bangs on a round brush. Trim the bangs every 4–6 weeks.
3. Side-Swept Fringe With Long Hair
Side-swept bangs that cross the forehead make the top of a diamond face read wider. I razor the fringe on an angle and cut long layers starting at the chin. Any density of straight to wavy hair works. Pull the fringe across with a flat brush as it dries and curl the ends on a 1.25-inch iron. Trim the bangs every 4–6 weeks and the length every 10–12.
4. Textured Side-Fringe Pixie
A textured pixie suits a diamond face as long as the fringe is long and swept across the forehead. I leave three to four inches on top, point-cut for texture, and keep the sides soft rather than tight so the cheekbones do not look exaggerated. Fine to medium straight hair carries it well. Dry the fringe sideways and finish with light pomade. Trim every 5–6 weeks.
5. Long Pixie Tucked at the Ears
A long pixie tucked behind the ears shows off the strong cheekbones of a diamond face while the fringe broadens the forehead. I cut the sides long enough to tuck and point-cut texture into the top. Fine to medium straight hair works. Dry the fringe forward and off to one side, then tuck. Of the diamond face shape hairstyles here, it is among the bolder ones. Trim every 5–6 weeks.
6. Wavy Bob at the Chin
A wavy bob cut at the chin builds the jaw width a diamond face is missing. I cut internal layers so the waves spread at the bottom rather than at the cheekbones. Medium-density 2A to 2C waves are the right match. Scrunch mousse through wet hair and diffuse. Refresh on day two with water and a light cream. Trim every 6–8 weeks.
7. Shoulder Shag With a Fringe
A shoulder-length shag with bangs widens the forehead and fills out the jaw, which balances wide cheekbones. I razor the layers and keep the shortest below the cheekbones. Medium to thick wavy hair carries it well. Let it air-dry with sea salt spray, or diffuse it with mousse worked in. Women over 30 after an easy air-dry cut also do well with it. Trim the bangs every 4 weeks and the shag every 8–10.
8. Lob With Fullness at the Jaw
A collarbone lob with volume built in at the jaw balances a narrow chin. I cut internal layers from the jaw down and point-cut the ends so they bend outward. Fine to thick straight or wavy hair works. Wave the lower half on a 1.25-inch iron and leave the top smooth. Among diamond face shape hairstyles, it is one of the most wearable. Trim every 8–10 weeks.
9. Full Blunt Fringe
Full blunt bangs broaden a narrow forehead and shorten a diamond face. I cut them straight across at the brow and take a wide section from temple to temple. Medium to thick straight hair carries them well. Dry the bangs down first with a flat brush. Shoulder-length or longer hair goes with them. Trim the bangs every 3–4 weeks.
10. Wispy Fringe
Wispy bangs soften a narrow forehead without the weight a full fringe brings. I cut a wide, thin section and point-cut to the brow so it spreads temple to temple. Fine to medium straight hair is the right match. Dry the bangs side to side on a flat brush. Pair them with layers that begin at the chin. Trim every 3–4 weeks.
11. French Bob With a Fringe
A French bob ends somewhere between the cheekbone and jaw and adds a brow-level fringe, which widens the forehead and frames the cheekbones. I cut it blunt with a slight bend through the ends. Fine to medium hair with some wave works. Air-dry with texture cream or blow-dry it smooth. Of the short diamond face shape hairstyles, it is a classic. Trim every 6–8 weeks.
12. Italian Bob at the Jaw
An Italian bob sits at the jaw with a heavy perimeter, adding the width a diamond face lacks at the chin. I cut it blunt and add internal layers so the volume moves. Medium to thick hair carries it well. Dry on a large round brush and push the volume to the ends rather than the crown. Women over 30 after a polished short cut do well with it. Trim every 6–8 weeks.
13. Layers That Start at the Chin
Layers beginning at the chin put fullness at the jaw, whereas layers that start at the cheekbones add width where a diamond face is already widest. I begin the shortest layer at the chin and point-cut downward from there. Fine to thick straight or wavy hair works. Dry the ends outward on a round brush. For most diamond face shape hairstyles, this is the easiest change to make. Trim every 8–10 weeks.
14. Deep Side-Parted Lob
A deep side-parted lob pushes hair across a narrow forehead and lays a diagonal line over the face. I cut it at the collarbone with a few layers on the heavy side. Fine to medium straight hair works, and the part lifts the root. Blow-dry it and tuck the lighter side behind the ear to reveal the cheekbone. Trim every 8 weeks.
15. Butterfly Cut, Layers From the Chin
A butterfly cut normally starts the short layers at the cheekbones, but on a diamond face I bring them down to the chin. The volume then sits at the jaw and the cheekbones do not read wider. Medium to thick hair is required. Dry on a large round brush and roll the ends outward. Women in their 20s and 30s after plenty of movement do well with it. Trim every 8–10 weeks.
16. Chin-Length Curly Bob
A curly bob adds width at the jaw, which is exactly what a diamond face needs. I cut it dry, curl by curl, to the chin and shape it fuller at the bottom than at the cheekbones. 3A to 3C curls are the match. Put leave-in and gel on soaking-wet hair, then diffuse. Schedule a dry cut every 10–12 weeks to hold the shape.
17. Curly Shag and Curly Bangs
A curly shag with curly bangs broadens the forehead and fills in the jaw. I cut it dry and hold the shortest layers below the cheekbones. Medium to thick 2C to 3C curls work. Do a wash-and-go using curl cream and gel, then diffuse. For curly hair it ranks with the best diamond face shape hairstyles. Trim the bangs every 4–6 weeks.
18. Long Layered Curls
Long curly layers get wider toward the bottom on their own, which balances a narrow diamond chin. I cut the layers dry, starting at the chin, so the curls spread below the cheekbones. Any density of 3A to 3C curls works. Put leave-in and gel through wet hair and diffuse it. On day two, refresh with water and a light curl cream. Trim every 12 weeks.
19. Twist-Out at the Shoulders
A shoulder-length twist-out carries more fullness at the bottom than the top, which suits a diamond face. I shape the cut so the length sits at the shoulders and the crown stays low. 4A to 4C hair is the match. Twist damp hair with a twisting cream, let it dry all the way, then unravel and fluff the ends. It holds three to five days. Reshape every 8–10 weeks.
20. Chin-Length Silk Press Bob
A silk press bob cut at the chin gives natural hair a sleek line that widens the jaw. I cut it after the press so the line sits correctly when straight, and I put in a side part. Natural hair of medium to thick density carries it well. Wrap it at night and keep it out of humidity so it lasts one to two weeks. Trim every 6–8 weeks.
21. Bixie With a Full Fringe
A bixie, part bob and part pixie, keeps soft length around the ears and a full fringe across the forehead. On a diamond face that widens the top without crowding the cheekbones. I point-cut the whole shape. Fine to medium hair works. Rub a light texture paste through dry hair. Trim every 6–8 weeks.
22. Asymmetrical Bob With a Long Fringe
An asymmetrical bob cuts a diagonal across a diamond face and keeps the eye moving. I cut one side at the chin and the other an inch longer, with a long fringe on the heavy side. Straight hair of medium density carries it well. Dry smooth with a paddle brush and finish with shine serum. The heavy fringe side also lifts the root. Trim every 6–8 weeks.
23. Inverted Bob With a Side Fringe
An inverted bob angles longer toward the front, placing length and fullness around the jaw. On a diamond face I keep the front at the chin, add a side fringe and graduate the back for shape. Fine to medium straight hair works. Dry on a round brush and bend the front pieces inward. Women over 40 after a polished bob do well with it. Trim every 6–8 weeks.
24. Flipped-Out Textured Lob
A textured lob with the ends flipped out at the collarbone adds width at the bottom of a diamond face. I cut it blunt with a few long layers so the flip holds. Straight hair of medium density carries it well. Dry on a large round brush, turning the ends out, and finish with light hold spray. Side-swept bangs add more width at the forehead. Trim every 8 weeks.
25. Feathered Fringe
Feathered bangs flick out at the temples and widen a narrow forehead. I razor them and blend them into feathered layers that begin below the cheekbones. Medium to thick straight or slightly wavy hair works. Dry the bangs forward, then out to the sides, on a round brush. A flexible-hold hairspray keeps the flick in place. Trim every 4–6 weeks.
Starting the shortest layer at the chin instead of the cheekbones is the simplest fix for a diamond face, since it skips the widest point. FYI, that one change does most of the work. The oval face haircuts guide runs through the rest of the shapes.
