Most guides to men’s hair types make it sound simple. Straight, wavy, curly or coily. Pick the one that looks closest to yours and move on.
The problem is that men’s hair doesn’t always fall clearly into one category. Length can change what you see, styling products can hide the natural pattern, and different areas of your head may not behave exactly the same way.
That’s where the commonly used 1A to 4C hair type system can be helpful and frustrating at the same time. It gives you a useful way to describe your hair, but those subtype boundaries aren’t exact measurements.
The first job, as I see it, is simply working out what your hair naturally does.

The 4 Main Men’s Hair Types
A common way of describing men’s hair types is to group the natural pattern into four broad categories: straight, wavy, curly and coily. You’ll see those called Type 1 through Type 4, with A, B and C used to describe variations within each group.
I’d treat those subtypes as rough descriptions rather than precise categories. Your hair can fall somewhere between two of them, and the pattern can vary across different areas of your scalp.
I’d start by getting the broad type right.
Type 1: Straight Hair
Type 1 hair dries without forming an obvious wave, curl or coil.
1A hair is at the straightest end, with very little natural bend or movement. 1B is still clearly straight but tends to show a little more body. 1C can develop slight bends in places without forming a consistent wave pattern.
Length can make those differences easier to spot. Very short straight hair may simply stand up or fall in the direction it has been cut. With more length, you get a better chance to see whether the strand actually stays straight or starts developing a repeating bend.
A few sections bending around the ears or changing direction at the front don’t automatically mean you have wavy hair. Look at what most of your hair does as it dries. If the majority stays straight from root to end, Type 1 is still the better fit.
Type 2: Wavy Hair
Type 2 hair forms a visible S-shaped pattern rather than staying straight or turning into full curls.
2A hair has loose waves that can be difficult to see at shorter lengths. 2B develops a clearer S-shape through more of the hair, while 2C has stronger waves and may include sections that start turning into loose curls.
This is one of the easiest men’s hair types to misread.
Short 2A or 2B hair can look almost straight because there may not be enough length for the wave to fully appear. Grow it out and the pattern can become far more obvious.
Strong 2C hair creates the opposite problem. Some sections may curl enough that deciding between strong waves and loose Type 3 curls becomes difficult.
I wouldn’t get stuck on that borderline. Look at what most of your hair does naturally and how the pattern develops at the length you actually keep it.
Type 3: Curly Hair
Type 3 hair forms recognizable curls or spirals rather than an S-shaped wave.
3A hair tends to produce larger, looser curls. 3B forms tighter, springier spirals, while 3C has smaller and more tightly formed curls.
One of the easiest ways to recognize curly hair is to watch it dry naturally. Instead of bending from side to side, sections begin turning back around themselves and forming more complete curves or spirals.
You may also see a noticeable difference between wet and dry length. As the curl pattern returns, the hair contracts and can appear considerably shorter than it did when wet or stretched.
Different areas don’t have to match perfectly. Your curls might be looser at the front and tighter around the sides or back. I’d judge the broad type from the pattern you see across most of your hair, not one unusually loose or tight section.
Type 4: Coily Hair
Type 4 has the tightest natural pattern in this classification. I’d treat it as its own pattern rather than simply describing it as an extreme version of curly hair because the bends and coils can form differently.
4A hair tends to form small, visible coils. 4B often has tighter bends where the pattern looks less circular, while 4C describes a very tight pattern where individual coils may be harder to pick out at a glance.
Shrinkage can be especially noticeable with coily hair. A strand can have considerably more actual length than you see when the natural pattern is fully contracted.
For that reason, pulling a strand straight doesn’t tell you much about its natural type. Look at the pattern after the hair has returned to its normal state.
Type 4 hair can also look very different from one man to another even when the coil pattern is similar. Some of that difference comes from the individual strands themselves and simply how much hair you’re working with overall.
Why the 1A to 4C Hair Type System Doesn’t Tell You Everything
Straight, wavy, curly and coily tell you the natural pattern of your hair. They don’t tell you whether the individual strands are fine or coarse, or how densely your hair grows across your scalp.
That distinction matters. Two men can both have Type 3A curls, for example, but one might have very fine strands while the other has coarse ones. Their curl pattern could look similar while the hair itself feels and behaves very differently.
Strand thickness describes the diameter of each individual hair. Fine strands have a smaller diameter, coarse strands have a larger one, and medium strands fall somewhere between.
Hair density is different. It describes how much hair you have growing across your scalp. You can have lots of fine strands packed closely together, or fewer strands that are individually much coarser.
This is why the phrase “thick hair” can be misleading, I think. One man may mean that each strand feels thick, while another means he simply has a lot of hair. Those are different characteristics and can create different problems when you cut or style the hair.
Take someone with fine strands but high density. He can have plenty of overall bulk while still finding that a heavy styling product pulls the individual hairs down quickly. Separating strand thickness from density explains that far better than the curl or wave type alone.
How to Work Out What Hair Type You Actually Have
The easiest time to judge your hair type is when nothing is changing its natural pattern. Wash it, leave styling products out, and let it dry naturally without brushing, blow-drying or forcing it into a particular shape.
Don’t judge it while it’s still wet. Water can stretch waves and curls, while rough towel drying can disturb the pattern and create frizz that makes your natural texture harder to see. Let it dry first.
Then look at the overall pattern. Hair that dries mostly straight points toward Type 1. A repeating S-shape suggests Type 2, recognizable curls point toward Type 3, and tight coils or bends indicate Type 4.
You don’t need every area to match.
Next, look at an individual strand. Take one hair between your fingers if you can.
Fine strands can be difficult to feel, medium strands are easier to notice, and coarse strands feel more substantial. Treat that as a rough comparison rather than trying to make an exact measurement at home.
Density takes more judgment. Check several areas rather than judging it from your hairline or one part.
If the hair separates easily and plenty of scalp is visible between the strands, density may be lower. If you have to move a lot of hair before much scalp becomes visible, it may be higher.
That’s only an estimate. Strand thickness, hair length and the contrast between your hair and scalp can all change how much scalp appears visible.
Photos can be useful here, I’ve found. Look at your hair from the front, sides, crown and back rather than relying entirely on what you can see in a bathroom mirror. You may find that the pattern or apparent density changes across different areas.
You don’t need to force your hair into a perfect subtype. Get the broad pattern right, work out whether your strands are fine, medium or coarse, and get a sensible idea of your density. That gives you enough information to start making better decisions.
How Your Hair Type Should Change Your Haircut and Styling
This is where knowing those differences becomes useful. A haircut can behave very differently on straight, wavy, curly and coily hair, and strand thickness and density can change the result again.
With straight hair, length can make a big difference to how much shape you get. Fine straight hair can start falling flatter as more length and weight are added, while coarse straight strands may resist bending into certain styles. High-density straight hair can also create plenty of bulk even when the individual strands aren’t particularly coarse.
Wavy hair gives you natural movement to work with, but some of that movement can disappear when the hair is cut very short. Leave more length and the wave becomes easier to see. If that movement is one of the things you like about your hair, choosing a cut that keeps enough length for it to develop makes more sense than fighting it straight every morning.
Curly and coily hair need more attention to finished length. Shrinkage means the hair may look much shorter once it returns to its natural pattern, so the important measurement isn’t simply how long a strand looks when it’s wet or pulled straight.
Styling products need the same kind of judgment. With fine strands, I’d generally start lighter because heavy creams, waxes or pomades can pull the hair down quickly.
Coarse hair is different, but that doesn’t automatically mean reaching for the strongest or heaviest product. A coarse strand may handle more product weight, but the hold you need still depends on the haircut, density and the result you’re trying to create. With curls and coils, keeping the natural pattern visible may matter more than maximum hold, especially if a stiff product leaves the hair looking worse.
Density affects the haircut too. Even fine strands can add up to real bulk once density gets high enough. With lower density, removing too much hair can make the scalp more noticeable, so taking weight out simply because a particular cut calls for heavy texturizing isn’t always the right move.
Imagine two men with 2B hair. One has fine strands and high density, while the other has coarse strands and lower density.
Their wave type is the same, but I wouldn’t automatically give them the same advice on weight removal or styling product. That’s where knowing the rest of your hair starts paying off.
Verdict: Know Your Hair, Not Just the Number
I think the 1A to 4C hair type system is worth knowing because it gives you a straightforward way to describe the natural pattern your hair forms.
Just don’t mistake the subtype for a complete description of your hair.
Once you know the broad pattern, strand thickness and density, pay attention to what happens at the length you actually keep your hair. That’s where you start seeing which cuts leave too much weight, which ones remove too much, and which styling products actually suit the hair in front of you.
If your pattern falls somewhere between two subtypes, that’s fine. You don’t need the perfect letter to understand your hair well enough to make better decisions.
