Thick hair has a mind of its own. You section it, you smooth it, you turn your back for thirty seconds — and somehow it’s already plotting its next act of rebellion. That’s precisely the gap a good straightening brush for thick hair is built to close: a tool that brushes, detangles and heat-smooths in one motion, instead of forcing you to fight your hair one two-inch clamp at a time.

So what actually is a straightening brush for thick hair? It’s a heated styling tool with bristles rather than flat plates, combining a hairbrush and a flat iron into a single pass that detangles dense, high-volume hair while smoothing the cuticle with consistent ceramic or ionic heat. As Wikipedia’s overview of hair irons notes, the straightening brush format is a relatively recent branch of a much older tool family, with the first dedicated ceramic straightening brush design only patented in 2013.
Here in the UK, thick hair brings its own quirks — damp mornings, indoor heating that dries strands out over winter, and a climate that seems engineered to reintroduce frizz the second you step outside. On paper, that means the tool you choose needs two things working in tandem: genuine heat retention (thick hair pulls heat away from bristles fast) and bristle density that can actually part a full head of hair, not just skim the surface. We’ve spent time digging through real specifications, aggregated reviewer sentiment, and independent comparisons to bring you seven genuinely useful options — from budget-friendly workhorses to a splurge-worthy salon-grade pick — plus the buying knowledge to choose confidently.

Quick Comparison: Straightening Brushes for Thick Hair at a Glance
Before we dig into the full breakdown, here’s a snapshot to help you jump straight to a shortlist.
| Product | Heat Range | Standout Feature | Best For |
|---|---|---|---|
| TYMO Ionic Plus | 80°C–230°C, 16 settings | Dense bristles built for thick hair | Best overall value |
| ghd Glide+ | Fixed 185°C | Salon-grade one-stroke smoothing | Best premium pick |
| Revamp Progloss Deepform | 130°C–210°C | Oil-infused ceramic bristles | Best for shine-focused styling |
| TYMO Ring Plus | 9 settings, LED display | Titanium coating for even heat | Best mid-range all-rounder |
| LANDOT Straightener Brush | 120°C–230°C, 12 settings | High-heat range on a budget | Best for coarse, resistant hair |
| MiroPure Enhanced Ionic | 16 settings | Auto temperature lock | Best for beginners/safety-conscious |
| MEGAWISE Pro Ceramic Ionic | MCH, 20-second heat-up | Fastest heat-up in this list | Best for rushed mornings |
Looking at the spread here, there’s no single “best” straightening brush for thick hair — there’s a best one for your hair and your morning. The TYMO Ionic Plus earns its top billing because its temperature ceiling (230°C) and bristle density are specifically engineered around coarse, high-volume hair, while the ghd Glide+ sits at the top of the price ladder because you’re paying for consistency and brand-backed engineering rather than raw heat. If speed is your priority over sheer power, the MEGAWISE Pro Ceramic Ionic‘s 20-second heat-up genuinely changes how a rushed morning feels.

Top 7 Straightening Brushes for Thick Hair: Expert Analysis
We’ve grouped these across budget, mid-range and premium tiers, and included variants in bristle design and heat technology so there’s a genuine option here whatever your hair — and your bathroom counter — needs.
1. TYMO Ionic Plus — dense bristles built specifically for thick hair
The clue is in the name: TYMO built this one around the exact problem thick-haired readers are trying to solve, and the bristle spacing reflects that from the first stroke. The 16-setting range (80°C–230°C) is unusually granular for this price point, and the top end genuinely matters — many rival brushes cap out around 200°C, which simply isn’t enough heat retention once you’re working through a dense, three-pass head of hair. Ten million ions are claimed to work alongside the ceramic heating element, aiming to counteract the static and frizz that dense hair tends to generate as it’s brushed. Based on the spec comparison with cheaper alternatives in this category, the dual voltage function is a genuinely useful inclusion rather than a marketing add-on, since it means the brush works on both UK and continental sockets without a converter. Reviewers consistently report that the dense bristle rows grip more hair per stroke than the wider-set competitors, which in practice should mean fewer overall passes for a full head. A recurring theme in user feedback is that the highest heat settings are needed to get truly resistant, coarse sections lying flat — this isn’t a tool that pretends lower heat will do everything.
Pros:
- ✅ Bristle density built specifically for thick hair
- ✅ Wide 16-setting range up to 230°C
- ✅ Dual voltage for UK and travel use
Cons:
- ❌ Lower settings underwhelm on stubborn sections
- ❌ Heavier in hand than slimmer rivals
At around £35–£45, this sits firmly in the “buy once, stop Googling” bracket — a strong value verdict for anyone whose hair has previously chewed through cheaper tools.

2. ghd Glide+ — best premium one-stroke smoothing
ghd didn’t build a temperature dial into the Glide+, and that omission is the whole point: the brand’s position, echoed across independent reviews, is that 185°C is the specific point at which hair enters what’s often called its “glass transition phase” — pliable enough to reshape, not so hot that you’re cooking moisture out of the strand. What most buyers overlook about this model is that the fixed temperature isn’t a limitation so much as a design philosophy borrowed directly from ghd’s professional straighteners, where consistency has always mattered more than raw heat ceiling. The bristle configuration — a mix of shorter tension bristles and longer detangling bristles — is engineered to work through larger sections in a single pass, which on paper suits thick hair better than brushes that need repeated re-combing. Aggregated reviewer sentiment is notably consistent for a beauty tool at this price: testers repeatedly describe it gliding through dense, frizzy hair without snagging, and note a genuine reduction in static thanks to the built-in ioniser. The trade-off, and it’s a real one, is that a single fixed setting means you can’t dial things down for finer sections mixed through a thick head, and the lack of adjustability won’t suit anyone who likes precise control.
Pros:
- ✅ Consistent 185°C engineered for minimal damage
- ✅ Detangles and smooths in one stroke
- ✅ Auto sleep mode after 60 minutes idle
Cons:
- ❌ No adjustable temperature settings
- ❌ Premium price versus budget alternatives
Expect to pay in the £125–£140 range — a genuine splurge, but one that reviewers repeatedly frame as justified by build quality and consistency rather than gimmicks.
3. Revamp Progloss Deepform — best oil-infused UK favourite
Revamp’s Deepform range leans hard into a genuinely different idea: bristles infused with keratin, argan and coconut oils, released gradually as the brush heats. Here’s what to weigh — the deep-set, extra-long “cool” bristles sit alongside the heated ceramic ones specifically so you can detangle larger sections before the heat ever touches them, which on paper should reduce the number of times you’re dragging a heated tool through the same knot. The 130°C–210°C range sits lower than some rivals, and that’s a deliberate design choice rather than a shortfall — Revamp markets this brush across all hair types, so the ceiling is tuned for versatility rather than maximum power. For genuinely thick, coarse sections, that upper 210°C setting is where you’ll want to sit rather than experimenting lower down. Independent reviewers have praised the tool’s premium feel — swivel cord, weighty handle, matte finish — and its shine payoff, attributing the extra gloss to the oil infusion rather than the heat alone. What reviewers note less favourably is that, being a UK-voltage-only appliance, it isn’t suited to travel outside the country without a transformer.
Pros:
- ✅ Oil-infused bristles add visible shine
- ✅ Deep-set bristles detangle before heat
- ✅ Premium build with 360° swivel cord
Cons:
- ❌ Lower maximum heat than some rivals
- ❌ UK voltage only, not travel-friendly
At around £45–£65, this lands as a considered mid-range purchase — worth it specifically if shine and hair condition matter to you as much as raw straightness.
4. TYMO Ring Plus — best titanium even-heat mid-ranger
The Ring Plus takes a different technical route to the same goal, swapping a purely ceramic heating surface for a titanium coating designed to distribute heat more evenly across the bristle rows. Based on the spec comparison with TYMO’s own Ionic Plus, this model trades outright heat ceiling (9 settings between roughly 121°C–210°C) for tighter, more consistent heat delivery — titanium is a faster, more even conductor than ceramic alone, which matters when you’re trying to avoid hot spots on a dense head of hair. The LED display is a small but genuinely useful addition, since guessing your temperature on a brush without one is a common frustration reported by reviewers of cheaper models. A sunken button design is intended to stop the brush switching off mid-stroke, a fiddly problem that turns up repeatedly in reviews of older-generation heated brushes. Reviewers consistently flag the anti-scald thermal frame as a genuine safety plus rather than marketing fluff, particularly for anyone new to heated brushes who’s nervous about touching the barrel by accident. Where it falls slightly short of the Ionic Plus is outright bristle density for very thick hair — it’s built more for “medium-thick” than the most stubborn, wiry textures.
Pros:
- ✅ Titanium coating for even heat spread
- ✅ Clear LED temperature display
- ✅ Anti-scald thermal insulation frame
Cons:
- ❌ Lower top temperature than dedicated thick-hair models
- ❌ Bristles less dense than the Ionic Plus
Sitting around £45–£55, it’s a sensible middle path for buyers who want reliability and safety features over maximum raw heat.
5. LANDOT Straightener Brush — best budget high-heat option
LANDOT is a less familiar name on the UK high street, but the spec sheet punches above its price point: 12 temperature settings spanning 120°C–230°C, explicitly marketed as suitable “for fine to coarse hair,” which is a wider claimed range than most budget competitors attempt. What most buyers overlook about lesser-known brands like this is that the underlying components — ionic ceramic bristles, fast heat-up — are often functionally similar to pricier alternatives, with the savings coming from brand marketing spend rather than build quality cuts. On paper, the 30-second fast-heat claim puts it in the same bracket as far pricier tools, and the dual voltage support is a genuine bonus for anyone who travels. Where honesty matters most here: verified, large-scale review data for newer entrants like this is thinner than for an established name like TYMO or ghd, so treat aggregated sentiment with slightly more caution and lean on the returns policy of wherever you buy. What is consistent across the reviews that do exist is praise for the anti-scald exterior and the genuinely wide heat range for the price, alongside occasional comments about the plastic housing feeling less premium under sustained daily use.
Pros:
- ✅ Wide 120°C–230°C range for the price
- ✅ Claimed 30-second fast heat-up
- ✅ Dual voltage for UK and travel
Cons:
- ❌ Less established review history than major brands
- ❌ Housing feels less premium than pricier rivals
Typically priced around £25–£35, this is the pick for anyone testing whether a straightening brush suits their routine before committing to a bigger spend.

6. MiroPure Enhanced Ionic — best for beginners and the safety-conscious
MiroPure’s pitch centres on control rather than raw power, and the auto temperature lock is the standout here: once you’ve dialled in a setting, the brush won’t accidentally shift up or down mid-style, which sounds minor until you’ve had a cheaper brush creep to a higher heat during a rushed morning. Paired with an auto-off function, this is a brush built with a specific buyer in mind — someone newer to heated styling tools, or someone who’s simply had a scare with a less safety-focused model in the past. The 16-setting range gives genuine flexibility across a mixed household (fine-haired teenagers, thick-haired parents), and the ionic technology is aimed squarely at frizz reduction rather than raw straightening speed. Reviewers consistently note that the anti-scald housing stays genuinely cool to the touch even at higher settings, a detail that matters more than it sounds for anyone brushing close to the scalp. Where it’s less convincing, according to aggregated feedback, is outright grip on very coarse, wiry hair — the bristles are described as smoother rather than as aggressively “toothed” as the LANDOT or TYMO Ionic Plus, so multiple passes may be needed on the densest sections.
Pros:
- ✅ Auto temperature lock prevents drift
- ✅ Anti-scald housing stays cool to touch
- ✅ Wide 16-setting temperature range
Cons:
- ❌ Less bristle grip on very coarse hair
- ❌ May need extra passes on dense sections
At around £30–£40, it’s a smart pick if safety features and gentle control matter more to you than sheer straightening speed.
7. MEGAWISE Pro Ceramic Ionic — best fastest heat-up on a budget
For anyone whose morning routine is measured in minutes rather than leisurely rituals, the MEGAWISE’s headline claim — a 20-second heat-up via MCH (metal ceramic heater) technology — is the entire sales pitch, and on paper it’s a genuine point of difference. MCH elements are generally faster to heat and more stable than standard ceramic coils, which is why professional dryers and some premium straighteners use the same underlying tech; seeing it filter down to a budget brush is a reasonable value proposition. The auto-off safety function and dual voltage support round out a feature set that, frankly, looks more expensive than the price tag suggests. Reviewers consistently highlight the quick heat-up as the standout real-world benefit — genuinely useful when you’re running late and don’t want to stand around waiting. The trade-off, and it’s worth being upfront about it, is that MEGAWISE doesn’t publish as granular a temperature range as some rivals, so precise control for very specific hair conditions (colour-treated, chemically relaxed) is more limited than on brushes with wider, clearly labelled setting counts.
Pros:
- ✅ Genuinely fast 20-second heat-up
- ✅ Auto-off safety function included
- ✅ Dual voltage for home and travel
Cons:
- ❌ Less granular temperature control
- ❌ Fewer long-term reviews than major brands
Priced around £25–£35, it’s the pick for speed-focused mornings where waiting for a brush to heat up simply isn’t an option.
Getting the Best Results: Your First 30 Days With a Straightening Brush
Buying the right straightening brush for thick hair is only half the job — how you use it in those first few weeks genuinely shapes both the results and how long the bristles stay effective. Start on the lowest setting that gets the job done, even if it means a slower first session; thick hair often needs less heat than you’d assume once it’s fully dry and properly sectioned, and dialling straight up to maximum out of impatience is the single most common mistake reviewers mention when a brush “stopped working as well” after a few months. Always work on completely dry hair — every manufacturer in this list is explicit that these tools are designed for dry use only, and running a heated brush through damp thick hair both undermines the styling result and risks genuine heat damage, since water inside the hair shaft turns to steam under heat.
Section generously but not excessively: thick hair benefits from being split into four to six sections rather than two, since trying to force a brush through a two-inch-thick chunk of hair defeats the entire “single stroke” promise these tools are built around. For maintenance, unplug and let the brush cool fully before wiping the bristles with a dry cloth — product build-up on the ceramic surface is the most common cause of uneven heat distribution over time, and it’s avoidable with thirty seconds of care after each use. A heat protectant spray isn’t optional here; because you’re making repeated passes rather than one clean glide (as with a traditional flat iron), thick hair styled with a brush is exposed to heat for longer in total, and a protectant genuinely reduces the cumulative moisture loss. It’s also worth being mindful of the scalp itself, not just the lengths — the British Association of Dermatologists notes that heated styling tools used too close to the roots carry a genuine risk of scalp burns, particularly on tightly coiled or very thick hair, so keeping bristles a small distance from the scalp on the first pass is a simple habit worth building in.
Which Straightening Brush Suits Your Life? Three Real-World Scenarios
Rather than a generic recommendation, it helps to match a brush to an actual routine. If you’re a university student commuting across a British city with 20 minutes before your first lecture, speed matters more than anything else — the MEGAWISE Pro Ceramic Ionic‘s 20-second heat-up and lower price point make sense here, especially on a student budget where a £130 splurge isn’t realistic.
If you’re managing thick, colour-treated hair and styling it most days for work, the calculation shifts toward heat control and hair condition. Here, the Revamp Progloss Deepform‘s oil-infused bristles and moderate 130°C–210°C range are built for exactly this use case — frequent styling with an eye on long-term shine and condition, rather than maximum raw power. And if you’re someone with genuinely coarse, resistant hair who’s tried cheaper tools and been disappointed by results that don’t last past lunchtime, the TYMO Ionic Plus or ghd Glide+ are the sensible pair to compare — one prioritising outright heat ceiling and bristle grip, the other prioritising engineered consistency at a fixed, research-backed temperature.

Problem → Solution: Fixing Common Thick-Hair Straightening Frustrations
Frizz returns within hours. This is usually a heat-versus-humidity mismatch rather than a faulty brush — on paper, higher-ion-output models like the TYMO Ionic Plus or MiroPure Enhanced Ionic are specifically built to neutralise the static charge that draws in ambient moisture, so pairing one with a lightweight anti-humidity spray tends to outperform simply raising the temperature further.
The brush glides but doesn’t fully straighten. Reviewers consistently trace this back to speed — moving too quickly through a section doesn’t give the heat time to reshape the hair’s internal bonds. Slowing each pass down, even by a second or two, tends to solve this before you need to reach for a hotter setting.
Results don’t last through a humid British afternoon. Consider whether your current brush’s ceiling temperature is genuinely high enough for your hair’s density — models capped around 200°C, like several budget options, may simply not be reaching the “glass transition” heat that holds a style through changeable weather; the ghd Glide+‘s research-backed 185°C fixed point exists precisely to solve this reliably.
Bristles feel less effective after a few months. This is almost always product build-up rather than genuine wear. A weekly clean with a dry cloth once fully cooled, plus avoiding styling products applied directly before use, resolves most cases reported in aggregated reviews.
How to Choose a Straightening Brush for Thick Hair
Picking the right straightening brush for thick hair comes down to a handful of criteria that matter far more than flashy marketing claims:
- Maximum temperature. Look for a ceiling of at least 210°C–230°C; thick, coarse hair genuinely needs more sustained heat than fine hair to reshape properly.
- Bristle density and spacing. Tightly packed bristles grip more hair per stroke, meaning fewer overall passes and less cumulative heat exposure.
- Heating technology. Ceramic offers even, gentle heat; titanium heats faster and more intensely, which often suits denser hair better.
- Ionic output. Higher ion counts are marketed to reduce frizz and static — genuinely useful for hair prone to flyaways after styling.
- Safety features. Auto shut-off, anti-scald housing and temperature locks matter more than they might seem, especially for daily use.
- Voltage compatibility. Dual voltage is a small line on a spec sheet that becomes very relevant the moment you try to pack for a trip abroad.
- Cord length and swivel. A longer, swivelling cord makes a genuine difference to comfort during a full styling session, particularly with thick, time-consuming hair.
Ceramic Hot Air Straightening Brush vs Traditional Flat Iron
It’s worth being direct about this comparison, because the two tools solve genuinely different problems. A ceramic hot air straightening brush combines detangling and heat styling into a single motion, which on paper should reduce total styling time for thick hair that would otherwise need a separate brushing-out stage before a flat iron ever touches it. A traditional flat iron, by contrast, uses two flat plates that clamp the hair directly, generally producing a more precise, poker-straight finish on individual sections — which is why professional stylists often still reach for one when working on very specific pieces or a client’s fringe.
| Factor | Ceramic Straightening Brush | Traditional Flat Iron |
|---|---|---|
| Styling speed on thick hair | Faster overall (brushes + straightens) | Slower (requires separate detangling) |
| Precision on small sections | Lower | Higher |
| Learning curve | Easier for beginners | Steeper, especially at speed |
| Risk of hair damage | Lower per pass (less clamping tension) | Higher if over-passed |
| Best For | TYMO Ionic Plus, ghd Glide+ | Detail work, fringes, precise finishes |
Reading the table, the honest takeaway is that most people managing thick hair day-to-day will get more consistent, faster results from a brush, while a flat iron remains worth keeping around for precision touch-ups. Reviewers who own both tools frequently describe using the brush for 90% of a routine and the flat iron only for stray pieces near the hairline — a genuinely sensible two-tool approach rather than an either/or decision.

High Heat Setting Straightener: What Thick, Coarse Hair Actually Needs
There’s a persistent myth that more heat is always better, and it’s worth unpacking honestly. A high heat setting straightener genuinely does matter for thick, coarse hair — the hair shaft is denser and takes longer to reach the internal temperature needed to reshape its hydrogen bonds, so a brush that maxes out at 150°C simply won’t achieve the same result as one reaching 220°C or beyond, no matter how many passes you make. That said, “high heat setting” doesn’t mean “always use the highest setting” — it means having the headroom available for the sections that genuinely need it, while still being able to dial down for finer regrowth or previously colour-treated lengths mixed through the same head. On paper, a wide, granular range (12–16 settings, as offered by the TYMO Ionic Plus and LANDOT Straightener Brush) gives far more practical control than a brush offering only three or four broad presets. What reviewers note repeatedly is that a genuinely high ceiling combined with a heat protectant spray outperforms a lower-heat brush used without one — the protectant matters more for hair health outcomes than shaving 20 degrees off your chosen setting.

Coarse Hair Styling Tool: Features That Actually Matter (And Those That Don’t)
Marketing copy for any coarse hair styling tool loves to list numbers — ion counts in the millions, wattages, setting counts — but not all of them translate to a noticeably different result. Bristle density and material genuinely matter: closely packed, heat-resistant bristles grip more hair per pass and are the single biggest factor separating a brush that “works” from one that just gets hot. Heating element type matters too — titanium and MCH both heat faster and more evenly than basic ceramic coatings, which is genuinely useful on coarse hair that pulls heat away quickly. Auto shut-off and anti-scald housing matter for safety, not styling quality, but they’re worth paying attention to regardless. Where the marketing tends to overstate things is ion count specifics — the difference between “5 million ions” and “10 million ions” isn’t something most reviewers can reliably distinguish in real-world frizz reduction, and cord length, while a genuine quality-of-life feature, has zero bearing on how straight your hair actually ends up. If you’re comparing two coarse hair styling tools with similar bristle density and heat ceilings, the tie-breaker should usually come down to safety features and build quality rather than whichever one advertises the bigger ion number.
Thick Hair Smoothing Brush vs Standard Straightening Brush: What’s the Difference
The terms get used almost interchangeably in marketing, but there’s a genuine distinction worth understanding. A thick hair smoothing brush is generally engineered around bristle density, spacing and heat retention specifically for high-volume, resistant hair — wider tooth gaps to grip more hair, higher sustained heat ceilings, and often a heavier overall build to handle longer styling sessions without overheating internally. A standard straightening brush, by contrast, is frequently designed as a general-purpose tool aimed at the broadest possible customer base, which in practice can mean a lower maximum temperature and finer bristle spacing better suited to fine or medium hair. Based on the spec comparison across this list, the TYMO Ionic Plus and LANDOT Straightener Brush both lean clearly toward the “built for thick hair” category, while the MiroPure Enhanced Ionic sits closer to a genuinely all-purpose tool that happens to work adequately on thicker sections. If your hair is unambiguously thick or coarse, it’s worth resisting the urge to buy whichever brush is cheapest or most heavily advertised, and instead checking the bristle spacing and maximum temperature specifically — the difference in real-world results between a general brush and a thick-hair-specific one tends to be larger than the price gap between them.
Common Mistakes When Buying a Straightening Brush for Thick Hair
The most common misstep, based on aggregated reviewer feedback across this category, is prioritising price over maximum heat ceiling — a brush that’s £10 cheaper but caps out at 180°C will likely leave a thick-haired buyer disappointed within the first few uses. A close second is ignoring bristle density entirely; two brushes can list identical temperature ranges while performing very differently because one has noticeably denser, better-spaced bristles. Buyers also frequently overlook voltage compatibility, assuming (often incorrectly) that a brush bought in the UK will work seamlessly abroad without checking the dual voltage claim specifically. Another recurring pattern in reviews is buying based on ion count alone, treating a bigger number as automatically better, when in practice bristle design and heat consistency do more of the actual styling work. Finally, skipping the maintenance instructions is a mistake that compounds over time — a brush that isn’t cleaned regularly will genuinely underperform its own specifications within a matter of months, regardless of how well-engineered it was on day one.
Long-Term Cost & Maintenance
Thinking beyond the sticker price genuinely changes which of these seven makes sense for you. A £30 brush that needs replacing every twelve months because the bristles degrade under daily thick-hair use may cost more over three years than a £120 brush built to last considerably longer — this is where the ghd Glide+‘s premium price starts to look more reasonable, particularly for anyone styling daily. On the other hand, if you’re an occasional user — weekends, special occasions — a lower-cost option like the MEGAWISE Pro Ceramic Ionic or LANDOT Straightener Brush is unlikely to be pushed hard enough to reveal any long-term shortfall, making the lower upfront cost the smarter call.
Maintenance costs are worth factoring in too: heat protectant spray is a genuine ongoing expense (expect to budget a modest amount every few months for regular users), and it directly extends both hair health and, indirectly, the working life of the bristles themselves by reducing product build-up from damaged, over-processed strands. Warranty length is another underrated value signal — Revamp’s two-year guarantee and ghd’s two-year warranty both suggest manufacturer confidence in long-term durability, which is worth weighing against cheaper alternatives offering shorter or less clearly stated cover.
Safety, Regulations & Electrical Compliance Guide
Heated hair tools are a genuine household fire and burn risk if handled carelessly, and it’s worth taking this seriously rather than treating it as small print. According to guidance from Electrical Safety First, mains-operated hair tools sold in the UK must be fitted with a proper three-pin UK plug and fuse, and should always be unplugged when not in use rather than left resting on a surface while still connected. The same guidance recommends buying from reputable retailers rather than unverified third-party sellers, since counterfeit or non-compliant units may not have passed the necessary UK safety checks — a genuinely important point given how many near-identical-looking heated brushes circulate online. If you don’t already have RCD (residual current device) protection built into your consumer unit, an RCD plug adaptor on the socket you use for styling tools is a cheap, sensible safeguard. The London Fire Brigade also specifically flags hair straighteners as a tool that gets “extremely hot,” recommending they’re always switched off and left to cool on a heatproof surface rather than a bedspread, towel or carpet. None of the seven brushes in this guide are exempt from these basics — regardless of price tag, unplug after use, check your cable regularly for damage, and never leave a heated brush unattended near children or pets.
