Is a blunt bob suitable for a diamond face with thin hair?

Yes, it's a good fit because it adds fullness near your narrow jaw and chin. Keep an eye on side volume, which can also widen the cheek area.

Are curtain bangs better than side-swept bangs?

Side-swept bangs are a top pick here. Curtain bangs are a neutral fit because they cover the forehead but can also add width beside already-wide cheekbones.

Should I choose long layers to make thin hair look fuller?

Shorter lengths and blunt ends read fuller than long layers. Start with a shorter, blunter outline if fuller-looking ends are your main aim.

Add fullness where your face narrows

A diamond face has cheekbones that are clearly wider than both the forehead and jaw. Aim for width at the forehead and chin, with nothing bulky at cheekbone level. Hair falling forward widens your forehead, while ends near the jaw add fullness lower down.

Thin hair changes little about this outline on its own. For diamond-face haircuts with thin hair, placement still matters: extra width beside the cheeks sits on your face's widest line.

Start with a lob, side-swept bangs or a textured bob

Lob: a good fit because it adds fullness at jaw and chin level, where your face is narrower.
Side-swept bangs: a good fit because they cover part of the forehead and shorten the visible face.
Textured bob: a good fit because it adds fullness near your jaw and chin. Watch where the texture sits, since it can also add width beside the cheeks.

Keep thin hair shorter and blunter, and avoid styles that depend on density. When choosing a bob for a diamond-shaped face, ask for fuller-looking ends near the jaw rather than bulk beside your cheekbones.

Check the tradeoffs before choosing another style

Blunt bob: a good fit for fullness near your jaw and chin. Check that the sides don't add bulk at cheekbone level.
Curtain bangs: a neutral fit. Forehead coverage shortens the visible face, but the sides also add width beside your cheekbones.
Soft waves: a neutral fit. Their soft, broken-up lines take the edge off a strong jaw but also widen the cheek area.
Pixie: needs a tweak because it exposes the full outline and puts your face's width on show.
Sleek straight: needs a tweak for the same reason. Consider some forward-falling hair rather than leaving the entire outline exposed.

Short hairstyles for a diamond face with thin hair still need the right outline. A shorter cut alone doesn't decide where the fullness lands.

Match your reference to the hair you have

A common mistake is choosing a cut designed for another hair type and expecting product to make it work. Ask your stylist to keep the ends blunt enough to read fuller, with width near your chin. Avoid choosing long layers when your main aim is fuller-looking ends.

The hairstyle guide lets you compare cuts across hair types and face shapes. The free face-shape finder names the closest face-shape prototype from one selfie, on your device. It doesn't read hair type, so choose that yourself from how your hair dries naturally.
