If you have looked at Denman brushes on Amazon, you have probably felt the confusion: a dozen near-identical black brushes with names like D3, D4, D31 and D41, and no obvious way to tell which one is right for you. It is one of the most common questions in the curly-hair world, and the honest answer is simpler than the product pages make it look.
The whole Denman range really comes down to one thing: how many rows of pins the brush has, and how close together they sit. Once you understand that, picking the right one takes about two minutes. This guide breaks down the models that actually matter, explains which suits your hair, and helps you buy once rather than guessing.

The quick answer
Most curly and wavy people want the D3 (7-row), the classic that defines curls beautifully on short to medium hair. Choose the D4 (9-row) if your hair is longer, thicker or denser and you want more grip. Choose the 5-row if you have short hair, want something gentler, or need a compact brush for travel. Here they are side by side.
How Denman brushes actually differ
Denman styling brushes all work the same way: rows of round-ended nylon pins set into a rubber cushion, spaced to grip your hair, distribute product, and clump curls together into defined pieces. This is the technique curlies call “denman-ing” or “brush styling,” and it is what gives you smooth, defined curls rather than frizz.
The models differ on two things: the number of rows (more rows means a bigger brush and more tension) and how close together the pins sit (closer pins give more definition, wider-spaced pins glide more gently and snag less). More rows and closer pins equals more definition and control. Fewer rows and wider pins equals gentler detangling and less pull. That is genuinely the whole system.
Denman D3 (7-row): the best all-rounder for most curly hair
The D3 is the original Denman styler and the one most curly-hair guides call the gold standard. Its 7 rows of close-set pins are the sweet spot for defining curls: enough grip to clump and shape your pattern, without so much tension that it drags or causes breakage. It is the multi-tool of the range, used for detangling, styling, smoothing and defining, and it works across most wavy and curly hair on short to medium lengths.
If you are new to brush styling and not sure where to start, this is the answer. It is the most forgiving, the most versatile, and the one the largest number of people end up happiest with. Only look elsewhere if your hair is very long and thick, or very short.
Best for: most wavy to curly hair, short to medium length, and anyone starting out. Skip if: your hair is very long and dense, or very short.

Denman D4 (9-row): best for longer, thicker hair
The D4 is the D3’s bigger sibling. It adds two more rows of close-set pins, for nine in total, which means more surface area, more grip and more tension in each stroke. That extra tension is exactly what longer, thicker or denser hair needs to define properly, and it is also why the D4 is a favourite for smoothing and blow-dry styling.
The trade-off is that all that grip can feel like too much on fine or short hair, tugging rather than gliding. If your hair is on the longer side, or simply thick and dense, the D4 gives you the control the D3 sometimes cannot. If your hair is fine or short, the D3 or the 5-row will feel kinder.
Best for: longer, thicker, denser hair, and smoothing or blow-dry styling. Skip if: your hair is fine, short or easily tugged.
Denman 5-row styler: best compact and gentle option
The 5-row Denman is the smallest of the styling brushes, and it fills a real gap. With fewer rows it is lighter, narrower and gentler, which makes it ideal for short hair, for getting into smaller sections, and for anyone who finds the 7-row D3 to be more brush than they want. It is also the natural travel pick, since it takes up less space in a bag.
You lose some of the clumping power of the bigger brushes, so it is not the choice if maximum definition on long hair is your goal. But for short styles, gentle everyday use, or a second brush to travel with, it is genuinely handy.
Best for: short hair, gentle everyday use, small sections and travel. Skip if: you have long, thick hair and want maximum definition.
Which Denman brush for your curl type?
If you would rather choose by your hair rather than the model number, here is the short version:
Wavy hair (type 2): your hair is finer and flattens easily, so you want closer pins for definition without weight. The D3 is the sweet spot; the 5-row works well for shorter waves.
Curly hair (type 3): the D3 is the classic pick for short to medium curls, and the D4 for longer or thicker curls that want more tension and grip.
Coily hair (type 4): tighter coils are more fragile, so detangle first with a wide-tooth comb, then use the D3 or D4 gently for definition. If any brush snags, a well-known trick is to remove every other row of pins so hair passes through more easily.
Frequently Asked Questions
What is a Denman brush and what does it do?
A Denman brush is a styling brush with rows of round-ended pins set in a rubber cushion. For curly hair, it grips and clumps your curls together as you brush product through soaking wet hair, creating smooth, defined curls with less frizz. The same brush also detangles, smooths and helps with blow-dry styling, which is why it is such a popular multi-purpose tool.
What is the difference between the Denman D3 and D4?
The main difference is size and tension. The D3 has 7 rows of pins and the D4 has 9, with both sets of pins spaced closely for definition. The extra two rows on the D4 give more grip and tension, which suits longer, thicker or denser hair, while the D3 is the more versatile all-rounder for short to medium hair. If you are unsure, most people are happiest starting with the D3.
Is a Denman brush good for curly hair?
Yes, a Denman is one of the most popular tools for defining curls. The pins are spaced to grip and clump curls together rather than separating them into frizz, which enhances your natural pattern. It works across wavy, curly and coily hair, though very tight or fragile coils should be detangled with a wide-tooth comb first and brushed gently.
How do you use a Denman brush on curly hair?
Apply your styling product to soaking wet hair, then take a section and brush from root to tip, letting the pins clump the curl together. Work in sections, re-shaping curls as you go, then air-dry or diffuse on low. Using it on wet hair with product is what creates definition; brushing dry hair will just cause frizz.
How many rows should my Denman brush have?
Choose fewer rows for shorter or finer hair and gentler use, and more rows for longer, thicker hair that needs extra grip. The 7-row D3 is the versatile middle ground that suits most people, the 9-row D4 adds tension for longer or denser hair, and the 5-row is the compact, gentle option for short hair and travel.
The bottom line
For most people the choice is simple: get the D3 (7-row). It is the classic, the most versatile, and the one the largest number of curly and wavy heads are happiest with. Reach for the D4 (9-row) instead if your hair is long, thick or dense and wants more grip, and pick the 5-row if you have short hair, want something gentler, or need a compact brush to travel with.
Whichever you choose, remember the technique matters as much as the brush: use it on soaking wet hair with product, work in sections, and let your curls dry undisturbed. Do that, and any of these three will help you get smoother, more defined curls.
