Curl Types From 2A to 4C: A Plain Guide for Men
The curl type chart sorts hair by the shape of a single strand. Type 1 is straight, type 2 is wavy, type 3 is curly and type 4 is coily, and the letters A, B and C run from looser to tighter within each number. So 2A is a soft, barely-there wave and 4C is a very tight coil with little visible pattern. For men, the chart is useful as a shared vocabulary: it helps you choose products, describe your hair to a barber and understand why the same cut looks completely different on two people. It is not a precise science, most heads carry two or three types at once, and it tells you nothing about thickness or how your hair takes moisture.
The system most people use was popularised by a celebrity hairstylist in the 1990s and has been adapted ever since. Treat it as a rough map, not a diagnosis.
The chart, in plain terms
| Type | What the strand does | What men usually notice |
|---|---|---|
| 2A | Loose S-bend, mostly straight at the root | Hair “kicks” at the ends; flattens easily with product |
| 2B | Clearer S-waves from mid-length | Some frizz in damp weather; good movement when longer |
| 2C | Defined waves starting nearer the root, odd loose ringlet | Puffs out at the sides; thick and heavy |
| 3A | Large, loose loops about the width of a thick marker pen | Clear curls once longer than a few centimetres |
| 3B | Springy ringlets roughly finger-width | Volume builds quickly; shape matters a lot |
| 3C | Tight corkscrews about pencil-width | Dense; noticeable shrinkage when dry |
| 4A | Small, defined coils | Coils visible when moisturised; dries out fast |
| 4B | Z-shaped bends rather than round coils | Less visible pattern; very soft if cared for |
| 4C | Very tight zig-zag with minimal visible definition | Heavy shrinkage; fragile if handled roughly |
How to work out your own type
- Wash with a plain shampoo and conditioner, no styling products. Product changes how curls clump and sit.
- Let it dry naturally, without touching it, towelling hard or brushing.
- Look at single strands, not the overall shape. Pull one gently from the crown, one from the side and one from the nape, and look at the shape each one makes when released.
- Compare against the descriptions above. If you are between two, you are probably both.
- Check again when it is longer. Short hair often hides its true pattern. Many men only discover their curl when they grow it out; we explain why in why hair gets curlier as it grows.
Why most men are more than one type
It is very common for the nape to be tighter than the crown, or for the front to be looser than the sides. Crowns, cowlicks and a lifetime of wearing hair one way also change how sections behave. This is the main practical point of the chart for a haircut: if the back is 3C and the top is 3A, the barber needs to cut them differently to get one even shape when dry. A single length all over will not sit evenly.
What the chart does not tell you
Two men with the same curl type can need completely different products and cuts. Three things matter as much as the pattern:
- Density: how many hairs you have. Dense 3B and fine 3B behave very differently.
- Strand thickness: fine strands are lighter and easier to weigh down; coarse strands hold shape but can feel wiry.
- Porosity: how readily your hair takes in and holds water. It explains why some hair drinks product and some lets it sit on top. Our guide to hair porosity for men has a simple home check.
What your type changes in practice
Products
Broadly, the looser the pattern, the lighter the product. Type 2 hair is easily flattened by heavy creams and usually prefers a light mousse, sea salt spray or a little gel. Type 3 tends to suit a leave-in conditioner and a curl cream or gel to hold definition. Type 4 generally needs more moisture: a water-based leave-in, then a cream or butter, with oils used to seal rather than to moisturise.
Shrinkage
The tighter the curl, the more length disappears as it dries. Type 4 hair can look a fraction of its stretched length. This is why we often cut tighter textures dry or check the shape once dry: what looks right wet can be much shorter by the time you get home. There is more on this in our post on afro hair shrinkage.
The cut
- Type 2: texture and weight removal on top stop it lying flat or puffing out.
- Type 3: cutting curl by curl or with the shape in mind avoids the triangle effect, where the sides balloon.
- Type 4: shaping with a pick and clippers or scissors on dry hair keeps the outline even; tapers and fades are cut to account for how the hair grows out.
How to describe your hair to a barber
The curl number is a good start but not the whole brief. A useful description sounds like: “Mostly 3B, tighter at the back, quite dense, gets dry quickly, I want to keep length on top.” That gives the barber pattern, variation, density, condition and goal in one sentence. At Highgate Cuts on Archway Road, every visit starts with an assessment anyway: the barber looks at your hair, asks what you need and makes recommendations before cutting. Coming in with your hair in its natural, product-free state makes that assessment much more accurate.
Questions we get asked
Can my curl type change?
Your pattern can shift with length, damage, heat, and sometimes over the years. It is common for hair to change gradually with age.
Is type 1 on the chart?
Yes, type 1 is straight. We started at 2A because straight hair rarely needs a curl chart to explain it.
Is 4C harder to cut?
Not harder, but it needs a barber who understands shrinkage and dry cutting. Ask how they check the shape once the hair is dry before you sit down.
