Best Silicone Free Round Hair Brush for Blowouts

The best silicone free round hair brush is the Cricket Static Free RPM 12 Row Round Hair Brush, a 27.2 g nylon-bristled brush that skips boar hair and shapes medium hair without snagging. If you have long, thick hair and want a wider barrel, the AIMIKE 3.3 inch boar-bristle brush is the better match. The deciding spec here is not the marketing on the box. It's barrel width and bristle material, and the two don't always agree with the silicone-free promise stamped on the listing.

How I screened these six brushes

Amazon's search for a silicone-free round brush returns a mixed bag, so I read each listing line by line before ranking anything. The goal was one clear question: what does the published data actually say, versus what the title implies?

I compared barrel size, weight, bristle material and stated dimensions across all six. Where a listing named its bristles, I used that. Where it stayed vague, I said so rather than guessing.

Two things stood out fast. First, "silicone-free" is not a spec any of these listings prints as a checkbox. It's inferred from the bristle description. Second, one pick openly lists silicone in its bristle blend, which matters a lot for this search.

• Kept: brushes with a clear bristle material and full dimensions.
• Flagged: the Terra brush, whose own listing names a silicone blend.
• Ranked on: barrel width, bristle type, weight, and how each fits a specific hair profile.

Every figure below is copied from the listing. Nothing is estimated. When a brush makes a claim I can't verify, I've attributed it to the maker instead of stating it as fact.

Best silicone free round hair brush at a glance

Does silicone-free actually matter here?

Silicone-free is a fair thing to want in a round brush. Some brushes use silicone-coated bristles or blended plastics, and if you're avoiding silicone across your whole routine, the brush is an easy thing to overlook.

Here's the honest part: Amazon's search for the best silicone free round hair brush pulled in at least one brush that openly lists silicone. The Terra Distribution brush describes bristles "blended with premium oil called squalene and silicon." That's the listing's own wording. So the search modifier isn't fully satisfied by the set, and I won't pretend it is.

What you can do is read the bristle line yourself:

1. All-nylon brushes name only nylon and rarely involve silicone. Both Cricket picks and the NaturaVol sit here.
2. Boar or boar-plus-nylon brushes use animal or natural fibre, not silicone. The AIMIKE 3.3 inch and the Conair fit this.
3. Blended plastic bristles are where silicone tends to hide. Read the fine print.

So the practical answer: several picks here read as silicone-free based on their stated bristles, but you should confirm on the live listing before buying, because a bristle formula can change without the title changing.

Barrel size is the real deciding spec

Most guides to the best silicone free round hair brush lead with bristle softness. That's not what decides your result. Barrel width is. It sets how much lift you get, how tight your curl bends, and whether the brush even reaches through your hair length.

A narrow barrel builds tighter curl and suits shorter or fine hair. A wide barrel smooths length and adds a soft bend rather than a curl. Match it to your hair, and a cheap brush outperforms a pricey mismatch.

Here's how the set lines up:

• AIMIKE 3.3 inch (claimed): the widest here, built for long hair and big smooth blowouts.
• AIMIKE NaturaVol, 1.7 inch barrel: a mid-width for shoulder-length hair and controlled bend.
• Cricket RPM 12: a 12-row nylon barrel at 27.2 g, light and all-purpose.
• Conair: a copper-coated metal barrel measuring 9.02 in long overall.
• Terra: an 8.03 in long body, slim at 1.42 in wide.

Weight tracks with barrel too. The Cricket brushes weigh 27.2 g. The AIMIKE NaturaVol runs 5.64 oz. That's the gap between a nimble finishing brush and a heavier tool you brace against your dryer.

1. Cricket Static Free RPM 12 Row Round Hair Brush — Best overall

The Cricket RPM 12 wins because it pairs an all-nylon, anti-static barrel with the lightest weight in the set, making it the safest silicone-free bet for everyday styling.

Best for: anyone smoothing medium-length hair who wants a light, all-purpose brush Skip it if: you need a wide barrel for long, thick hair

This is the pick I'd hand most people. At 27.2 g, it's tied for the lightest brush here, which matters over a long blow-dry when your arm starts to complain. The barrel measures 8.9 x 1.35 x 1.35 in, a slim profile that suits medium hair and fine sections.

Cricket calls the bristles anti-static nylon with ball tips, and describes them as non-snag on wet or dry hair. Those are the maker's claims, not lab results. What I can confirm from the data: the bristles are nylon, with no boar hair and no silicone blend named anywhere. For a silicone-free search, that clean bristle line is exactly what you want.

It's also the cheapest of the six and sells faster than the rest of this set. The listing says it's crafted in the USA and released in 2023. The trade-off is width. Against the AIMIKE brushes, this narrow barrel won't smooth long, thick hair as fast, and there's no heat-conducting metal core.

Pros:

• Lightest in the set at 27.2 g
• All-nylon bristles, no boar or silicone listed
• The cheapest pick of the six
• Anti-static nylon claim from Cricket
• Slim 1.35 in barrel for fine sections

Cons:

• Narrow barrel struggles on long, thick hair
• No metal or ceramic heat-conducting core
• Anti-static benefit is a maker claim, not verified

2. AIMIKE Round Hair Brush — Best for pros

This AIMIKE takes the widest barrel in the group and pairs it with boar bristles, making it the workhorse for long-hair blowouts.

Best for: stylists and long-haired blowout fans working a 3.3 inch barrel Skip it if: you specifically want to avoid boar bristles

If your hair is long and thick, barrel width does more for you than anything else, and AIMIKE claims a 3.3 inch overall diameter here. That's the widest in this roundup. A barrel that size smooths length in fewer passes and lays down a soft, rounded bend rather than a tight curl.

The listing ships it as a 5 piece set that includes 4 free clips, which is handy for sectioning. It weighs 5.29 oz and measures 3.15 x 7.09 x 3.94 in packaged. AIMIKE describes a vented ceramic-coated barrel for airflow and nano thermal ionic tech for shine. Those are the maker's words.

On silicone: the bristles are boar, a natural fibre, so silicone isn't in play here. Boar helps spread scalp oils down the strand, per the listing. The catch is that boar is exactly what some shoppers want to avoid for ethical or texture reasons. It also sells better than most of the set, sitting well ahead on category demand.

The trade-off against the Cricket: it's heavier, pricier, and that wide barrel is overkill on short or fine hair.

Pros:

• Widest barrel here, 3.3 in claimed
• Boar bristles, no silicone involved
• Ships with 4 free clips for sectioning
• Vented ceramic barrel claim for airflow

Cons:

• Boar bristles won't suit everyone
• Among the priciest picks in the set
• Too wide for short or fine hair
• Ionic and ceramic benefits are maker claims

3. AIMIKE NaturaVol Round Brush for Blow Out — Best premium

The NaturaVol is the most expensive pick here, earning it on a nylon-only bristle set and a ceramic ionic barrel aimed at flyaways.

Best for: flyaway-prone hair that wants a ceramic ionic barrel Skip it if: you're on a tight budget

The NaturaVol is the priciest of the six and the heaviest at 5.64 oz. What sets it apart in this set is that it combines a ceramic ionic barrel with all-nylon bristles, so you get the heat-tool feature without any boar or silicone in the bristle line.

AIMIKE lists a 1.7 inch barrel with a 2.5 inch overall diameter including bristles, and dimensions of 2.5 x 10.6 x 2.5 in. The maker describes two bristle shapes, wavy and straight nylon, plus negative ions during blow-drying to seal cuticles and cut flyaways. Read those as claims on the box, not measured outcomes.

For a silicone-free shopper who still wants ceramic and ionic tech, this is the cleanest match in the group. The mid-width barrel handles shoulder-length hair and a controlled bend well.

The honest cost: you pay the most in the set for a barrel that isn't the widest and bristles that aren't the softest natural fibre. Against the Cricket, it's heavier and more expensive for a similar bristle material.

Pros:

• Nylon-only bristles, no silicone or boar
• Ceramic ionic barrel for heat styling
• Two bristle shapes per the listing
• Mid-width 1.7 in barrel suits most lengths

Cons:

• The most expensive pick here
• Heaviest brush in the set at 5.64 oz
• Ionic and flyaway claims are unverified
• No published warranty in the listing

4. Conair Round Hair Brush — Best upgrade

Conair's copper-barrel brush is the fast-drying pick, using a metal core and a boar-nylon mix to move heat through coarse hair.

Best for: coarse or curly hair that dries slowly Skip it if: you want an all-nylon brush

The Conair is the one to reach for when drying time is the problem. It uses a copper-coated metal barrel, and Conair claims up to 50% better heat transfer, which is their figure, not mine. A metal core heats fast and holds warmth, so coarse and curly hair sets sooner.

The barrel measures 2.68 x 9.02 x 2.44 in and the brush weighs 3.53 oz, sitting mid-pack on both size and heft. It's a mid-priced option here. Bristles are a boar-and-nylon combination with ball tips, per the listing, so no silicone is involved. Conair says the boar helps distribute scalp oils for shine.

Released in 2016, it's the oldest design in the group, and there's a plain read on that: it's a proven shape rather than a new gimmick.

The trade-off is the bristle mix. If you want pure nylon and no boar at all, the Cricket or NaturaVol are better fits. A metal barrel also runs hotter to the touch, so mind your fingers near the ends.

Pros:

• Copper metal barrel for faster drying
• Boar-nylon mix, no silicone listed
• Mid-range price in this set
• Ball-tipped bristles to reduce snagging

Cons:

• Boar content rules it out for some
• Metal barrel gets hot near the ends
• 50% heat claim is Conair's own number
• Oldest design here, from 2016

5. Cricket Static Free Volumizer Hair Brush — Best minimal setup

The Cricket Volumizer is the lift specialist, using a vented crisscross nylon design to add fullness to fine, flat hair.

Best for: fine, flat hair chasing volume and lift Skip it if: you want a heat-conducting metal barrel

If your goal is body rather than curl, this Cricket is the targeted tool. It weighs 27.2 g, tying it as the lightest in the set, and measures 8 x 1.25 x 1.6 in. The name says it all: this one is built to lift.

Cricket describes a crisscross bristle design that raises hair at the root and vents that boost airflow from your dryer to cut drying time. Those are the maker's claims. The bristles are anti-static nylon with stay-put ball tips, so like the RPM 12, there's no boar and no silicone named. That keeps it clean for a silicone-free routine.

It's the second-cheapest pick here and the newest, released in 2024. For a shopper who wants one simple, light brush focused on volume, this is the least fussy choice.

The trade-off is the vented body. It has no metal or ceramic core, so it won't set a smooth blowout as fast as the Conair or the AIMIKE brushes. It's a volumizer first, a smoother second.

Pros:

• Tied for lightest at 27.2 g
• All-nylon, anti-static bristles, no silicone
• Vented design for airflow, per Cricket
• Second-cheapest pick in the set

Cons:

• No metal or ceramic heat core
• Vented body smooths slower than metal barrels
• Volume focus limits curl-shaping
• Airflow and static claims are unverified

6. Terra Distribution Anti Static Hairbrush — Most versatile

The Terra is a gentle daily detangler, but its listing names silicone in the bristles, so it lands last for a silicone-free search.

Best for: gentle daily detangling on damaged hair Skip it if: silicone-free is a hard requirement

I'm including this one for honesty, not to recommend it against the brief. The Terra's own listing describes bristles "blended with premium oil obtained from olive oil called squalene and silicon." Silicon in the bristle blend is precisely what a silicone-free shopper is trying to skip, so it ranks last here on that single, decisive point.

Set that aside and it's a pleasant brush. Made in Japan, it weighs 1.83 oz and measures 1.42 x 1.81 x 8.03 in, a slim, light body for daily use. Terra names a static-elimination fibre called NASLON and describes soft, painless plastic bristles. The material list reads AS resin, polyester resin and stainless steel. Those are the maker's descriptions.

For gentle detangling on fragile hair, the soft bristles have appeal. It's a mid-priced pick and the slowest seller of the six by a wide margin.

The trade-off is the whole reason you're reading this guide. If avoiding silicone is a firm rule, this one doesn't clear it, and any of the nylon or boar picks above serve you better.

Pros:

• Very light at 1.83 oz
• Soft plastic bristles for gentle detangling
• Made in Japan per the listing
• NASLON anti-static fibre claim

Cons:

• Listing names silicone in the bristle blend
• Slowest seller of the six
• No heat-conducting barrel
• Fewer published specs than rivals

Nylon, boar, or a blend: which bristle wins?

Bristle material is the second decider after barrel width, and it's where the silicone question actually lives. Here's the plain breakdown across the set.

• Nylon: the Cricket RPM 12, Cricket Volumizer and AIMIKE NaturaVol run nylon. It grips for smoothing and lift, and none of these listings name silicone.
• Boar: the AIMIKE 3.3 inch uses boar, a natural fibre that spreads scalp oil for shine. No silicone, but not for everyone.
• Boar-nylon mix: the Conair combines both, aiming for grip plus oil distribution.
• Silicone blend: the Terra lists silicon in its bristles. That's the one to skip if silicone-free is the goal.

There's no single winner. Nylon is the cleanest, most predictable choice for a silicone-free routine, which is why the top pick sits there. Boar wins on shine and oil spreading if you're fine with animal fibre. The blend on the Conair is a middle path. Read the bristle line on the live listing every time, because that one sentence decides whether a brush belongs in this search at all.

When a different brush wins

The Cricket RPM 12 is the default, but three specific situations flip the pick. Here's the if/then map.

• If your hair is long and thick, the AIMIKE 3.3 inch barrel wins. A narrow barrel makes you work three times as hard on length. Width is worth the extra weight.
• If drying time is your main gripe, the Conair copper barrel wins. A metal core moves heat that nylon barrels can't, and coarse hair sets faster.
• If you want ceramic and ionic tech but no boar, the AIMIKE NaturaVol wins. It's the only nylon brush here with a ceramic ionic barrel, at the cost of being the priciest.

One more: if your hair is fine and falls flat, the Cricket Volumizer beats the RPM 12 for lift, thanks to that crisscross vented design. The cutoff is your hair length and texture. Fine and short favours the light Cricket brushes. Long and thick favours the wide AIMIKE. Coarse and slow-drying favours the Conair metal barrel.

The verdict

If you want one silicone-free round brush for everyday styling, get the Cricket Static Free RPM 12. It runs all-nylon bristles with no boar and no silicone in the listing, weighs just 27.2 g, and costs the least of the six. For medium hair and general smoothing, nothing else here matches that combination of clean bristle line and low price.

The cutoff is hair length and texture. If your hair is long and thick, the AIMIKE 3.3 inch boar brush wins on the strength of the widest barrel in the set, claimed at 3.3 inches, plus 4 free clips for sectioning. That barrel width is its exact advantage over the Cricket: it smooths length in fewer passes, where the narrow Cricket barrel makes you work.

Between those two sits the AIMIKE NaturaVol for anyone who wants a ceramic ionic barrel with nylon bristles, and the Conair for fast drying on coarse hair. The one to approach with caution is the Terra, whose listing names silicone in the bristles. For a silicone-free search, that single line moves it to the back.

FAQ

Is a silicone free round hair brush worth it over a regular one?

A silicone free round hair brush is worth it if you're avoiding silicone across your whole routine and want your tools to match. The performance gap comes from barrel and bristle, not the silicone itself. The Cricket RPM 12 delivers clean all-nylon bristles at the set's lowest price, so you don't pay a premium to skip silicone.

Which round brush gives the best value here?

The best value here is the Cricket RPM 12. It's the cheapest of the six, weighs a light 27.2 g, and runs all-nylon anti-static bristles with no silicone named. You get a clean silicone-free bristle line and a proven brush shape without paying the premium of the AIMIKE picks or the mid-range Conair copper barrel.

What barrel size should I choose for long hair?

For long hair, choose the widest barrel you can. A wide barrel smooths length in fewer passes and adds a soft bend rather than a tight curl. The AIMIKE at a claimed 3.3 inch diameter is the widest in this set. Narrow barrels like the Cricket RPM 12 at 1.35 in suit fine or medium hair better.

Cricket RPM 12 or AIMIKE NaturaVol for flyaways?

Between the Cricket RPM 12 and AIMIKE NaturaVol, the NaturaVol targets flyaways more directly. AIMIKE claims its ceramic ionic barrel emits negative ions to seal cuticles, a maker claim. The Cricket relies on anti-static nylon bristles instead. The NaturaVol is heavier at 5.64 oz and the priciest here, so pay up only if flyaways are your main issue.

What's the biggest mistake buyers make with these brushes?

The biggest mistake buyers make is trusting the title and skipping the bristle line. A brush can carry "anti-static" in its name and still list silicone in the bristles, as the Terra does with its squalene and silicon blend. Read the material description on the live listing before you buy, because that one sentence decides if it's truly silicone-free.

Start by matching a barrel to your hair: narrow for fine or medium, wide for long and thick. Then read the bristle line and confirm it's silicone-free on the live listing, since formulas can change without the title changing. For most people, the Cricket RPM 12 is the right default. It's the lightest, cheapest brush here, its bristles are plain nylon with no silicone named, and it handles the everyday smoothing that most hair actually needs.
