How to know if a haircut will suit you before you cut it

By the FADR team · 31 October 2026 · 4 min read

Most haircut regret starts the same way: a photo that looked great on someone else. Whether a cut actually suits you comes down to three things you can check in advance, plus one test that beats all of them.

The short answer

A haircut is likely to suit you if it balances your face shape, works with your natural hair type, and fits the upkeep you're willing to do. The most reliable check is to see the cut on a photo of your own face before you book.

1. Find your face shape

Pull your hair back and look straight into a mirror, or use a front-facing selfie. Compare three widths: your forehead, your cheekbones and your jaw. Then compare the length of your face with its width. Whichever part is widest, along with whether your jaw is soft or angular, gives you your shape.

Outlines of the six common face shapes: oval, round, square, heart, long and diamond, each with its widest point marked — The six common face shapes. The dashed line marks the widest part of each face.

Oval: slightly longer than it is wide, with a softly rounded jaw. Most cuts work here, so choose based on your hair type and lifestyle.
Round: about as wide as it is long, with a soft jawline. Height on top or length past the chin adds structure, while very full sides and blunt chin-length cuts make your face look wider.
Square: a strong, angular jaw that's roughly the same width as your forehead. Texture, layers and side parts help soften the angles.
Heart: wider at the forehead and narrower at the chin. Volume around the jaw and side-swept fringes balance out the top of the face.
Long: clearly longer than it is wide. Fringes and fuller sides add width; tall styles on top just add height you don't need.
Diamond: widest at the cheekbones, with a narrower forehead and jaw. Fringes and fullness around the chin keep the cheekbones from looking too sharp.

Treat these as guidelines, not strict rules. Plenty of people wear the “wrong” cut for their shape and look great, which is why seeing a cut on your own face matters more than any chart. If you don't want to guess in the mirror, FADR measures your face shape from a selfie, on your phone, and ranks the styles that suit your proportions.

2. Be honest about your hair type

Every cut is built around a certain kind of hair. The same bob behaves very differently on fine, straight hair than it does on thick curls.

Texture: straight, wavy, curly or coily. Curly hair springs up as it dries, so it usually sits shorter than the length it was cut to.
Thickness: fine hair can fall flat in heavy, one-length cuts. Thick hair often goes bulky in short layers unless your stylist thins it out.
Growth patterns: cowlicks and double crowns decide where your hair naturally wants to sit, especially with short cuts and fringes.

3. Check the upkeep before you commit

A cut that needs more effort than you're willing to give it won't look like the reference photo for long.

Fades grow out fast. Most people book a touch-up every two to four weeks.
Fringes need a quick trim every few weeks to stay out of your eyes.
Big colour changes, like going platinum, usually mean root touch-ups every four to eight weeks, plus extra conditioning in between.
Styling time: if a look needs a blow-dry and product every morning, be honest about whether you'll actually do it on a Tuesday morning.

4. See it on your own face

Face shape, hair type and upkeep narrow things down, but seeing the cut on your own head is what settles it. These six people tested a new look in FADR before deciding. Drag any photo to compare.

Tip: look at your preview again the next day. If it still feels like you, it's probably a solid choice. If it feels like a costume, keep looking.

What a preview can't tell you

A preview is the best reference photo you can bring to the chair, not a guarantee. Hair density, cowlicks and the way your hair falls all affect the final result, and a good barber or stylist will adapt the cut to suit your head. Bring the preview, then let them do their job.

Before you book: a quick checklist

I know my face shape and the cut works with it (or I've seen it on my own face and like it anyway)
The cut suits my natural hair texture and thickness
I'm happy to keep up with the trims, colour and daily styling it needs
I have a photo of the cut on me ready to show my barber or stylist
