What haircut should I get? A hair-first way to choose, in the order barbers use

Start with the hair, not the face. Many barbers look at what a head of hair can physically do before they think about face shape. Wesley Cheung, a Calgary barber who writes about this, argues that your hair type decides a haircut more than your face shape does, and that your own lifestyle and preferences are the factor to weigh most ^[1]. A barber-training guide from Cadmen makes a related point from the chair: thick, dense hair and fine, thin hair behave completely differently at the same guard length ^[2].

So work through five checks in order. The hair checks rule out what can't work; upkeep, proportions and taste choose between what's left. The Fitcut engine is built the same way: curl pattern, hairline and how much length you would lose are hard checks that rule cuts out, and everything else, density included, is weighed against the rest.

1. 1

   Hair type

   Curl pattern decides which shapes your hair can hold at all; density decides how well it holds them.

2. 2

   Hairline

   Some cuts need a full front; others work at any stage.

3. 3

   Upkeep

   How often you will see a barber, and how long you will spend styling each morning.

4. 4

   Proportions

   Measured rather than guessed, and given less weight than the hair checks.

5. 5

   Taste

   Safe or bold, classic or current: your call among the cuts your hair passes.

Texture narrows the options more than anything else. Curl pattern is usually described on the 1A–4C scale: 1 is straight, 2 wavy, 3 curly and 4 coily, with A to C running from looser to tighter. For each texture, the table counts how many catalog cuts list it as a best fit or as workable, out of 47 in total.

Loose waves have the widest choice: 38 cuts list 2A as a best fit. Tighter curls have fewer, with 10 for 3C. That is a count of catalog cuts, not a ranking of hair types, and curly and coily hair have cuts designed around them, covered in the guides to curly hair for men and coily hair.

If your hair mixes two patterns, judge by the part people see most, usually the top and the front, on a day when you haven't styled it.

Yes, and it is a separate question from texture. Density is how many strands you have; strand thickness is how wide each one is. Stylists and barbers will tell you that fine, low-density hair shows the scalp through heavy layers and falls flat in cuts that rely on volume, while thick, coarse or curly hair can spread into a triangle in one-length shapes unless weight is taken out.

Two examples from the catalog show how much this matters. Classic pixie: Low to medium density, because thick, coarse hair needs debulking to sit close in such a short shape. Butterfly cut: Medium to high density, because its layers need enough hair to show.

Not sure where you sit? Look at your crown under bright light with your hair dry and unstyled. If the scalp shows easily, you are probably on the lower side; if you can barely see it, you are on the higher side.

If your hair has thinned noticeably or quickly, see a dermatologist before you plan a cut around it.

Your hairline sets a ceiling on how long the top can be before the front starts to look thin. The Fitcut engine uses the limits below, organised by the Norwood scale, which runs from no recession at stage 1 to advanced hair loss at stage 7.

Short cuts hold up well as a hairline changes. The classic taper works up to Norwood 3, the textured crop up to Norwood 3, and the buzz cut works at any hairline stage. Longer cuts that need a full front go first: curtains only hold up through Norwood 1. The receding hairline guide goes stage by stage, and the thinning hair guide covers a widening part.

A cut only works if you will keep it up. Two things matter: how often it needs a barber or stylist, and how long it takes to style each morning. Six cuts from across the catalog show how wide the range is:

The trade-off runs both ways. The buzz cut takes no styling at all but needs a barber every 2–3 weeks. The butterfly cut goes 8–10 weeks between trims but takes 10–20 min a day with a round brush and heat. The lob also goes 8–10 weeks between trims but takes 5–10 min a day with no heat, and the catalog describes it as near universal.

Be honest about your mornings. If the real answer is “nothing”, rule out anything that needs heat or product, however good it looks in photos.

Less than face-shape charts suggest, for two reasons. First, judging face shape by eye is unreliable. In a 2014 study of 313 school students aged 8 to 15, one examiner's visual classification of facial type (long, average or broad) agreed poorly with anthropometer measurements: a kappa of 0.189, on a scale where 1 is complete agreement and 0 is no better than chance ^[3]. Second, people misjudge their own faces. In a small 2017 study, 40 adults picked life-size images of their own face that were wider and shorter than the real thing ^[4].

Proportions still count for something: a cut can add height, cover the forehead or keep width at the temples. That is why Fitcut measures proportions from a photo instead of asking you to name a shape, uses them as one input among several, and never scores the face-shape label itself. The free face shape detector runs in your browser and shows your measurements and shape mix. The face-shape catalogs, such as men's cuts for an oval face and women's cuts for a round face, show how those rules play out.

Once the hair checks are done, taste decides. The catalog tags some cuts as statement cuts: bold looks that people tend to either love or skip, such as the modern mullet, the mod cut and the wolf cut. They rank on fit like any other cut, but the analysis only puts one first if you ask for bold cuts or nothing else fits nearly as well.

Safe doesn't mean dull. The classic taper and the lob are dependable because both work at any density and on straight, wavy or loosely curly hair. If you are unsure, start safe and go bolder at the next visit; that is far easier than growing out a bold cut you didn't like. For what people are asking for right now, see trending haircuts.

Several popular cuts come with clear limits in the catalog. If one of these describes you, look at the alternatives first:

• Butterfly cut: needs 1B–2C hair with enough density, plus a round brush and heat. Fine, low-density hair and tight curls lose the shape.
• Classic pixie: thick, coarse hair needs debulking to sit close, and a pixie grows out awkwardly, so it is a big commitment.
• Textured crop: a low forehead works against the choppy fringe, and on a very round face the top needs height rather than a flat finish.
• Mod cut: fine hair falls flat in it, and a low forehead or a front cowlick works against it.
• Curtains: an off-centre cowlick at the front fights the centre part, and the cut needs a full hairline.
• Buzz cut: it puts the shape of your head, any bumps and ears that stand out on show.

Write down the sides you want, how long the top should be, where the fringe sits, what the neckline looks like and how you style it, then add front, side and back photos of the cut. Two sample requests:

• Classic taper: “Scissor-over-comb sides, no skin fade, finishing around a #3–4 above the ears. Leave 2–3 in (5–7.5 cm) on top, swept to the side, and taper the neckline naturally.”
• Lob: “Collarbone length, blunt or with light long layers, the ends bevelled under. I air-dry most days, so cut it to fall into shape without a blow-dry.”

Each style page, like the one for the lob, has the full script. The guide on what to tell your barber covers guard numbers, barber vocabulary and photos in detail, and if you are torn between two kinds of sides, taper vs fade settles it.

1. What is my curl pattern on an unstyled day, and does the cut list it as a best fit?
2. Is my hair fine or coarse, low or high in density, and does the cut need volume or weight removal?
3. Does the top length stay within the limit for my hairline in the table above?
4. How often will I really see a barber or stylist, and how long will I style it each day?
5. Do I own, and will I use, the heat tools or product it needs?
6. Does it fit how I want to look at work and on weekends?
7. Safe or bold: which do I want this time?
8. Do I have front, side and back photos of it on hair like mine?
