A lot of cuts go wrong on a diamond face in one spot: the shortest layer lands at the cheekbones, which are already the widest part. The fix is dropping that layer to the chin and adding bangs to widen a narrow forehead. Each hairstyle for a diamond face shape below works that way, with hair type and trim timing noted.
1. Side-Banged Bob at the Chin
For fine to medium straight hair, a chin-length bob with side bangs answers the main problem of a diamond face, which is narrow at the forehead and jaw and widest at the cheekbones, so the best diamond face shape hairstyles add width at both ends. Fullness lands at the jaw from the bob and the forehead gets wider from the side bangs. The bob is cut blunt with light layers inside. Styling is a round brush with the ends bent under. Trim every 6–8 weeks.
2. Curtain Fringe With Long Layers
For fine to thick straight or wavy hair, curtain bangs widen a narrow forehead and fall toward the cheekbones without hiding them. The bangs are cut to part at the center and sit just above the cheekbones, with long layers point-cut from the chin down for fullness at the jaw. Styling is a round brush through the bangs. Trim the bangs every 4–6 weeks.
3. Long Hair, Side-Swept Fringe
For straight to wavy hair at any density, side-swept bangs across the forehead make the top of a diamond face look wider. The fringe is razored on a diagonal, with long layers kept from the chin down. Styling is a flat brush pulling the fringe across and a 1.25-inch iron through the ends. Trim the bangs every 4–6 weeks and the length every 10–12.
4. Side-Fringed Textured Pixie
For fine to medium straight hair, a pixie suits a diamond face when the fringe is long and swept across the forehead. Three to four inches stay on top, point-cut for texture, and the sides are left soft rather than tight so the cheekbones are not exaggerated. Styling is the fringe dried to the side and a light pomade. Trim every 5–6 weeks.
5. Ear-Tucked Long Pixie Cut
For fine to medium straight hair on someone willing to go bold, a long pixie tucked behind the ears shows off the strong cheekbones a diamond face has while the fringe widens the forehead. The sides are left long enough to tuck and the top is textured with point cutting. Styling is the fringe dried forward and to one side, then tucked. It counts among the bolder diamond face shape hairstyles. Trim every 5–6 weeks.
6. Wavy Chin Bob
For medium-density 2A to 2C waves, a wavy bob at the chin builds the jaw width a diamond face needs. Internal layers let the waves spread at the bottom instead of at the cheekbones. Styling is mousse scrunched into wet hair and a diffuser, with a day-two refresh of water and a light cream. Trim every 6–8 weeks.
7. Shoulder-Length Shag With Fringe
For medium to thick wavy hair, and for women over 30 who want an easy air-dry cut, a shoulder-length shag with bangs widens the forehead and fills the jaw to balance wide cheekbones. The layers are razor-cut with the shortest kept below the cheekbones. Styling is sea salt spray and air-drying, or mousse and a diffuser. Trim the bangs every 4 weeks and the shag every 8–10.

8. Collarbone Lob With Jaw Volume
For fine to thick straight or wavy hair, a lob ending at the collarbone with volume built in at the jaw balances a narrow chin. Internal layers run from the jaw down and the ends are point-cut so they bend out. Styling is a 1.25-inch iron through the lower half with the top left smooth. Few diamond face shape hairstyles are as wearable. Trim every 8–10 weeks.
9. Blunt Bangs, Cut Full
For medium to thick straight hair worn shoulder-length or longer, full blunt bangs widen a narrow forehead and shorten a diamond face. They are cut straight across at the brow from a wide section running temple to temple. Styling starts with the bangs dried down on a flat brush before anything else. Trim the bangs every 3–4 weeks.
10. Light Wispy Bangs
For fine to medium straight hair with layers beginning at the chin, wispy bangs soften a narrow forehead without a full fringe’s weight. A wide, thin section is point-cut to the brow so it spreads from temple to temple. Styling is a flat brush drying the bangs side to side. Trim every 3–4 weeks.
11. The French Bob With Fringe
For fine to medium hair with a little wave, a French bob that ends between the cheekbone and jaw with a fringe at the brow widens the forehead and frames the cheekbones. It is cut blunt with a slight bend at the ends. Styling is texture cream and air-drying, or a smooth blow-dry. Short diamond face shape hairstyles do not get more classic. Trim every 6–8 weeks.
12. Jaw-Length Italian Bob
For medium to thick hair, and for women over 30 who want a polished short cut, an Italian bob sitting at the jaw with a heavy perimeter adds the chin width a diamond face lacks. It is cut blunt with internal layers so the volume moves. Styling is a large round brush with the volume directed to the ends instead of the crown. Trim every 6–8 weeks.
13. Layers Beginning at the Chin
For fine to thick straight or wavy hair, layers that begin at the chin are the simplest change for most diamond face shape hairstyles, because layers starting at the cheekbones only add width where the face is already widest. The shortest layer starts at the chin and the point cutting runs down from there so the fullness sits at the jaw. Styling is a round brush drying the ends outward. Trim every 8–10 weeks.
14. Lob With a Deep Side Parting
For fine to medium straight hair that needs lift at the root, a deep side part sends hair across a narrow forehead and draws a diagonal across the face. The lob is cut at the collarbone with a few layers on the heavy side. Styling is a blow-dry with the light side tucked behind the ear to show the cheekbone. Trim every 8 weeks.
15. Butterfly Cut With Layers at the Chin
For medium to thick hair, and for women in their 20s and 30s who want lots of movement, a butterfly cut on a diamond face has its short layers moved from the cheekbones down to the chin. That sends the volume to the jaw and stops the cheekbones from looking wider. Styling is a large round brush with the ends rolled out. Trim every 8–10 weeks.
16. Curly Bob Cut Dry
For 3A to 3C curls, a curly bob delivers the jaw width a diamond face needs. It is cut dry, one curl at a time, to the chin and shaped fuller at the bottom than at the cheekbones. Styling is leave-in and gel on soaking-wet hair, then a diffuser. A dry cut every 10–12 weeks keeps the shape.
17. Curly Fringe Shag
For medium to thick 2C to 3C curls, a curly shag with curly bangs widens the forehead and fills out the jaw, which makes it one of the best diamond face shape hairstyles for curly hair. It is cut dry with the shortest layers kept below the cheekbones. Styling is a wash-and-go with curl cream and gel, then a diffuser. Trim the bangs every 4–6 weeks.
18. Long Curls With Layers
For 3A to 3C curls of any density, long curly hair balances a narrow diamond chin because it naturally widens toward the bottom. Long layers are cut dry from the chin so the curls spread below the cheekbones. Styling is leave-in and gel on wet hair with a diffuser, and a day-two refresh of water and a light curl cream. Trim every 12 weeks.
19. Shoulder-Length Twist-Out Style
For 4A to 4C hair, a shoulder-length twist-out suits a diamond face because it is fuller at the bottom than the top. The cut is shaped so the length sits at the shoulders and the crown stays lower. Styling is twisting damp hair with a twisting cream, letting it dry fully, then unraveling and fluffing the ends. It lasts three to five days. Reshape every 8–10 weeks.
20. Silk Press Bob at the Chin
For natural hair of medium to thick density, a silk press bob at the chin gives a sleek line that adds width at the jaw. It is cut after the press so the line sits right when straight, and a side part goes in. Nightly wrapping and staying away from humidity keep it going one to two weeks. Trim every 6–8 weeks.
21. Fringed Bixie Cut
For fine to medium hair, a bixie, which crosses a bob with a pixie, keeps soft length around the ears and a full fringe across the forehead. On a diamond face that adds width up top without crowding the cheekbones. The whole shape is point-cut. Styling is a light texture paste through dry hair. Trim every 6–8 weeks.
22. Asymmetrical Bob Cut
For straight hair of medium density, an asymmetrical bob draws a diagonal across a diamond face and keeps the eye moving. One side is cut at the chin and the other an inch longer, with a long fringe on the heavy side. Styling is a smooth paddle-brush blow-dry and shine serum. Root lift comes from the heavy fringe side as well. Trim every 6–8 weeks.
23. Inverted Bob Cut
For fine to medium straight hair, and for women over 40 who want a polished bob, an inverted bob angles longer at the front and puts length and fullness around the jaw. On diamond faces the front stays at the chin with a side fringe, and the back is graduated for shape. Styling is a round brush with the front pieces bent in. Trim every 6–8 weeks.
24. Flipped-Ends Textured Lob
For straight hair of medium density, a textured lob with the ends flipped out at the collarbone adds width at the bottom of a diamond face. It is cut blunt with a few long layers so the flip holds. Styling is a large round brush turning the ends out and a light hold spray. Side-swept bangs can be added for more forehead width. Trim every 8 weeks.
25. Feathered Bangs at the Temples
For medium to thick straight or slightly wavy hair, feathered bangs flick out at the temples and widen a narrow forehead. They are razor-cut and blended into feathered layers that start below the cheekbones. Styling is a round brush drying the bangs forward and then out to the sides, held with flexible-hold hairspray. Trim every 4–6 weeks.
A lot of cuts go wrong on a diamond face in one spot: the shortest layer lands at the cheekbone, which is already the widest point, so I move it to the chin. FYI, that one change does most of the work. The oval face haircuts guide runs through the rest of the shapes.
