    Face shapes covered

Women's haircuts by face shape (salon shape selection) turn a measured outline into a named cut you can book: a blunt lob, long layers, a shag, a pixie, curtain bangs, a deep side part, a blowout. The measurement says what the cut has to do. The name tells the person holding the scissors how.

Proportions set the brief. Cheekbone width, forehead width and jaw width across their widest points, plus face length from hairline to chin base, give the four figures behind every recommendation below. An oval sits near 1.5 on the length-to-cheekbone ratio with a jaw marginally narrower. A round outline holds length and cheekbone width within a few percent. A heart runs widest at the brow and finishes on a point.

Length ranges are the working vocabulary: a pixie above the ear, a French bob at the jaw, a lob at the collarbone, mid-lengths under it. Fringe families run blunt, curtain, side-swept, wispy and micro. Curl pattern and density modify all of them, since fine straight hair and dense curls answer the same instruction differently.

Google MediaPipe Face Mesh reads those figures from 468 landmark points in your browser, and the face shapes reference explains each category.

Seven sections follow, one per outline, naming cuts and the reason each works. Then five fringe families matched to the faces they suit, texture and density as a modifier, and the sentences that get you the cut you asked for.

Oval: cuts that preserve rather than correct

Oval proportions land near the averages salon shapes were designed around, so the job is preservation. Almost every named cut holds: a blunt lob, long layers, a French bob, a textured pixie, a shag.

Two combinations break it. Poker-straight one-length hair worn down a center part, with no interior shape, stretches the reading toward oblong. A dense fringe over a chin-length cut compresses the proportion into something boxy.

If you want bangs, keep them at brow level and let some skin show at the temples. The oval page covers why exposure of the upper third outranks any particular length.

Round: vertical lift and a lower perimeter

Round outlines need height added and mid-face fullness removed. Long layers beginning below the chin do both, since the shortest piece sits under the widest point.

A lob cut 2 to 5 centimeters past the jaw is the reliable short option, and an A-line version, longer at the front than the back, adds a diagonal against the curve. A textured pixie with crown height works at the other extreme. Curtain bangs open a vertical channel through the forehead.

Skip the chin-length blunt bob, one-length hair whose ends land at the cheeks, and dense straight fringes. See the round page.

Square: softening a corner without hiding it

Square faces hold forehead, cheekbones and jaw inside roughly 5 percent above a sharply angled corner. That corner is a feature, so soften rather than conceal.

Soft waves through the mid-lengths break the vertical plane of the cheek. Long layers opening at the collarbone keep weight below the mandible. A shag suits this outline as well as any, since its broken interior refuses to draw a second straight line. A side part beats a center part here.

Ends cut level with the jaw corner are the thing to avoid, along with a heavy blunt fringe laying a horizontal parallel to the bone. More at the square page.

Heart: adding weight where the outline narrows

Heart outlines finish on a point, so the useful cuts put mass at chin level. A blunt lob ending at or just below the chin adds width where the taper is steepest, and it is the most effective shape available here.

Layers should open at mandible level, not cheekbone level. Curtain bangs and side-swept fringes cut apparent forehead width, addressing the other half of the imbalance.

What undoes it: a tight center part with everything pulled off the face, a pixie carrying all its volume at the crown, and long hair layered up around the cheekbones. The heart page has the measurements.

Diamond: filling both narrow ends

Diamond proportions peak at the cheekbones between a narrow forehead and a narrow chin, so this outline wants fullness at both ends and the middle kept close.

A chin-length French bob delivers the lower half, since the ends sit under the cheekbone rather than beside it. Curtain bangs or a side-swept fringe broaden the brow. Layers should stop below the cheekbone line, never on it.

Flat roots with a center part narrow both regions that were already narrow, and hair scraped back off the forehead does the same. The diamond page explains where the width sits.

Oblong: shortening the vertical run

Oblong faces run clearly longer than wide with near-parallel sides, and a fringe is the fastest correction available. Blunt or soft, cut at brow level, it takes centimeters off the visible length.

For the rest, aim for horizontal interest between chin and collarbone. A collarbone-length blunt cut with waves through the ends adds width at ear and jaw height. Blunt perimeters beat tapered ones, since tapered ends draw the eye downward.

Long one-length hair with no fringe, high crown volume and tight top-knots all extend the run. See the oblong page.

Triangle: building the upper third

Triangle outlines carry the jaw as the widest measurement, tapering up to a narrower brow, which reverses the heart instruction. Volume belongs from the temples through the cheekbones.

A shag with a full, textured top does that better than any other named cut. A side-swept fringe broadens the brow. Ends should clear the mandible corner, and face-framing lightness at eye level pulls attention upward.

Blunt jaw-length shapes, one-length ends resting on the corner, and hair tucked flat behind the ears all add to the part already carrying the most. See the triangle page.

Five fringe families and the faces they fit

Section depth matters as much as outline. The same fringe taken from a shallow section on fine hair reads sparse, and from a deep section on dense hair reads solid. Ask how far back into the crown the section runs.

Texture and density as a modifier

Texture decides whether your hair can deliver what the outline asks for. Fine straight hair cannot hold width at the jaw without a blunt perimeter and product, so a triangle with fine hair barely worries about lower bulk, though it still needs root lift.

Dense coarse hair expands sideways by default, so a round outline with thick hair needs interior weight removed, not extra length added.

Curls follow their own rule: they expand where they are shortest. A layered curly cut with its shortest interior piece at the cheekbone builds a wedge of width where a round face wants none. Keep the short pieces at the crown and let the perimeter run long. All of this has to survive the conversation in the chair.

What to say to your stylist

Salon language is spatial, not adjectival. "Something that suits me" produces whatever the stylist enjoys cutting this season. Use sentences like these.

  • Name the widest height: "keep this widest at eye level, not at the jaw."
  • Name the perimeter against a landmark: "ends 3 centimeters below my jaw corner", never "shoulder length".
  • Ask where the interior stops: "how much weight comes out at the cheek, and where does the shortest piece sit?"
  • Give the fringe two numbers: "curtain, shortest at the brow, longest at the cheekbone, section 5 centimeters back."
  • Bring two photos, one of the cut you want and one of a cut you refuse. The negative reference carries more information.

Wear your hair straight and the shape should be checked dry and straight. Wear it curly and it should be cut dry and curly.

Salon shape selection, then, converts four measurements into a named cut. Oval takes preservation, round takes vertical lift, square takes softening that leaves the corner intact, heart takes weight at chin level, diamond takes fullness at both narrow ends, oblong takes a shorter vertical run, and triangle takes a built-up upper third. Five fringe families attach to the faces they fit, texture and density decide what your hair can hold, and spatial sentences get the result out of the chair. Measure first with the detector, then read face shape for men or the principles at the hairstyle hub.

Start with your face shape

Most styling decisions follow from one measurement. Run the detector, then work outward from the result.
