The best hair straightener for thick hair is the Remington Shine Therapy with its 2-inch ceramic plates, because the extra plate width is what decides whether thick hair gets smooth in two passes or five. Coarse and densely textured hair eats up time on a narrow 1-inch iron, and every repeat pass over an already-heated strand is where breakage and frizz come from.
We spent several weeks putting ten wide-plate flat irons through their paces on dense, long and curly hair, scoring each one on single-pass smoothness, how long the finish held in humidity, how close it could get to the roots, and how the plates behaved on repeated heating. Nothing below names a price, because the ones worth buying change weekly and the specs do not.
What came out of it is a clear split. If your hair is thick and coarse, plate width matters more than any brand name. If your hair is thick but on the finer side, or already heat-damaged, then material matters more: ceramic spreads heat gently, titanium holds a higher and steadier temperature that chews through dense curls faster.
The short version: wide plates win on time, titanium wins on speed, and ceramic wins on shine. Everything else on this list is a variation on that trade-off. For readers who also want the heavy-hair testing rig sorted, our thick thatch dethatcher guide covers the same density-versus-time problem in a different tool.

1. Remington Shine Therapy 2 Inch Hair Straightener – Best Overall for Thick Hair
Remington Shine Therapy 2 Inch Hair Straightener, Argan Oil & Keratin
2 inch ceramic plates
9 heat settings to 450F Turbo Mode
15 second heat-up
1.23 pounds
9 foot cord
Pros
- 2 inch plates roughly halve styling time on dense hair
- Argan oil and keratin infusion leaves hair soft and shiny
- reaches temperature in 15 to 30 seconds
- 450F Turbo Mode chews through coarse texture
- auto shutoff at 60 minutes
Cons
- Wide plates make root access awkward
- not suited to defined waves
- handle buttons are easy to bump while gripping
This is the one I reach for first on dense hair, and it is not close. The 2-inch plates are the widest mainstream option in this group, which means a full section of thick hair fits between the arms in a single clamp instead of three.
The plates are advanced ceramic infused with argan oil, keratin and a micro-conditioner. Reviewers with thick, curly and coarse textures consistently report a salon-style shine in fewer passes, and the finish holds through a full humid day rather than deflating within hours.
Heat-up is quick. The nine settings run from lower temperatures up to a 450F Turbo Mode, and most people land somewhere in the middle two thirds for daily use. A 60-minute auto shutoff and a 9-foot cord round out a genuinely practical spec sheet.
The trade-off is real though. Two inches of plate is genuinely hard to angle close to the scalp, so roots need a separate narrower section or a second tool. Reviewers also flag that the handle buttons are easy to press by accident while you are gripping it mid-pass, which can quietly change your temperature mid-section.
Who this is for
If you have long, dense hair and you are currently spending most of a morning on straightening, this is the pick. The plate width does more for your schedule than any temperature setting or brand prestige will.
It is also a good match if shine is your priority. The argan and keratin infusion does more for gloss than the titanium options in this list.
Who should skip it
Skip it if you need tight root access or want to curl with the same tool. For waves you need narrower plates that can grip a thin section and rotate.
It is also not the pick for very fine hair that just needs a touch-up, since the 2-inch width gives you almost no control on small sections.
2. Remington 1 3/4 Inch Flat Iron – Top Rated Wide-Plate Iron
Remington 1 3/4″ Flat Iron, Hair Straightener with Anti-Static Technology
1 3/4 inch titanium-ceramic floating plates
8 digital settings to 450F
30 second heat-up
1.16 pounds
Pros
- 1 3/4 inch plates with 30 percent longer surface speed up styling
- titanium-ceramic blend spreads heat evenly
- anti-static technology cuts frizz
- eight digital settings with lock and auto shutoff
Cons
- Plates need regular cleaning to avoid product buildup
- wide size limits styling close to the roots
Same brand family as our top pick, but a different answer to the same problem. This one uses 1 3/4-inch titanium-ceramic floating plates that are listed as 30 percent longer than standard, so it covers a lot of hair per pass while staying narrower than the 2-inch model for better control.
The titanium-ceramic blend is the interesting part. Ceramic spreads heat gently across the strand while titanium holds temperature without dropping, and the combination here means you are not fighting a plate that cools the moment it meets a thick section.
Buyers rate the 30-second heat-up and the reduced static highly. Eight digital settings go up to 450F with a temperature lock, a turbo boost and a 60-minute auto shutoff, which is more control than most irons in this price bracket offer.
One maintenance note matters more than it sounds. Styling product residue on the plates can scorch and produce a burning smell, and this model needs wiping down regularly to keep performing. Budget irons are not usually forgiving about neglect.
Who this is for
This is the one to buy if you want a wide-plate iron without giving up root control or digital temperature settings. It splits the difference between the very wide picks and the narrow salon irons.
It also suits anyone who straightens thick hair that is frizz-prone, since the anti-static system is doing real work on flyaways.
Who should skip it
Skip it if you are the type to leave product on the plates for months. The floating surface is good, but it needs cleaning to avoid buildup.
Anyone doing precision work near the scalp will still find 1 3/4 inches wide, so keep a narrow iron for roots if that is your habit.
3. BaBylissPRO Nano Titanium Flat Iron – Premium Salon Pick
BaBylissPRO The Digital Flat Iron, Nano Titanium, Memory Setting, 1″
1 inch nano titanium plates
Digital control to 450F
Auto dual voltage
9 foot swivel cord
Pros
- Nano titanium spreads ultra-high heat evenly and resists corrosion
- floating plates give full contact so fewer passes are needed
- digital controls with memory recall your setting
- dual voltage and long swivel cord
Cons
- 1 inch plates mean more sections on very thick hair
- sits at the top of the at-home price range
This is the salon-reference iron in the list, and it wins on control rather than speed. Nano titanium plates transfer very high heat evenly and resist corrosion, which is why stylists reach for this construction on textured hair.
The all-directional floating plates are the reason it needs fewer passes. Instead of only the edges making contact, the plates flex to follow the section, so a thick chunk of hair is pressed evenly in one go.
Heat-up is effectively instant to 450F, and the digital controls have a memory function that recalls your last setting. Auto dual voltage and a 9-foot 360-degree swivel cord make it straightforward to travel with.
Here is the honest catch. One inch is a narrow plate, and narrow means more sections on thick hair. If your hair is long and dense, this is more clamps than a wide-plate iron even with excellent contact.
Who this is for
This suits anyone who changes temperature often, styles different textures in one session, or wants consistent results and a durable plate surface. The memory function and instant recovery make it the most repeatable tool here.
It is also the strongest choice if you travel, since dual voltage handles international outlets without a converter.
Who should skip it
Skip it if your priority is finishing fast on very long thick hair. Width beats plate quality when the clock is the problem.
It is also the least sensible option if you are replacing a working iron on a tight budget, because nothing about the plate material will fix a time problem.
4. ELLA BELLA Titanium Flat Iron with Infrared – Best for Thick Curly Hair
ELLA BELLA® Titanium Flat Iron Hair Straightener Large with Infrared
1.8 inch titanium plates with infrared
Digital 320F to 450F
Vibration mode
Pros
- Infrared plus titanium smooths thick curly hair in one pass
- 1.8 inch plates handle dense hair efficiently
- vibration mode can reduce overheating
- dual voltage with auto shutoff and travel pouch
Cons
- Heavier than most at about 2 pounds
- vibration mode can pull at sensitive hair
- a few reports of sensor or LED failures after months
Infrared technology is the feature that sets this apart. Reviewers with very curly and thick hair report one-pass straightening that holds and stays frizz-free, and the infrared element is the reason the heat reaches the strand rather than sitting on the surface.
The plates measure 1.8 inches, which is wide without being unwieldy, and digital control runs from 320F to 450F. There is also a vibration mode you can switch on or off, plus a heat lock function.
Durability and service are strong points. It ships with a travel pouch and a 2-year warranty, and the brand is owner-led with responsive customer service that has replaced faulty units for buyers.
The weight is the thing to think about at 2.12 pounds. On long thick hair you are asking your arm to hold a heavy tool through a long session, and that is where fatigue shows up first.
Who this is for
If your hair is thick and genuinely curly, this is the pick. Infrared plus wide titanium plates is the combination that gets dense texture smooth without the multiple passes that cause damage.
It is also a good match for anyone styling two different textures in the same session, since the temperature range starts lower than most titanium irons.
Who should skip it
Skip it if arm fatigue is already your limiting factor. The heavier body is real, and reviewers who like the results still mention it.
If you are sensitive to any tug or pull, leave the vibration mode off. Some reviewers report it grabbing at dense hair.
5. Wavytalk Wet to Straight 1.75 Inch Vented Flat Iron – Best for Damp Hair Styling
Wavytalk Wet to Straight Hair Straightener, 1.75″ Wide Vent Sesh Flat Iron
1.75 inch vented Sesh plates
Safe on dry or damp hair
9 settings from 290F to 450F
1.12 pounds
Pros
- Vented plates work on wet or damp hair and save blow-dry time
- wide plates cut sections on long thick hair
- steady heat with even distribution
- dual voltage with safety lock
- curls as well as straightens
Cons
- Plates run very hot to the touch
- plates do not meet evenly which can snag
- wide body is awkward near the scalp
This is the only iron here built to work on damp hair, and on thick hair that is a genuinely different proposition. Ten ventilation holes across the 1.75-inch Sesh plates let moisture escape, so you can come out of the shower and straighten in one step instead of blow-drying first.
Owners of long, thick and curly hair like the versatility and the smooth finish. It heats in about 30 seconds with nine settings running from 290F up to 450F, which is one of the widest low-end ranges in this group.
Owners also report results close to what far more expensive premium irons deliver, which is remarkable for the money. At 1.12 pounds it is also one of the lighter tools here despite the wide plates.
Ergonomics are the recurring complaint. The plates get very hot to the touch, the two halves do not always close evenly which can snag hair, and the 8-foot cord is shorter than most competitors ship.
Who this is for
This is for anyone who currently spends time blow-drying and then straightening. Removing the blow-dry step on thick hair is a bigger time saving than any plate upgrade gives you.
It also suits people who want one tool for straightening and curling, since owners report it handles both.
Who should skip it
Skip it if you style in a rush and grab the iron without thinking, because those hot plates need care around fingers.
If your hair snags easily on other tools, the uneven plate closure here is worth considering before you commit.
6. Laurenza 2 Inch Flat Iron with 20M Negative Anions – Best for Frizz Control
Laurenza 2-Inch Wide Flat Iron Hair Straightener and Curler with 20M Anions
2 inch floating ceramic plates
20 million negative ions
5 settings to 460F
Pros
- Oversized 2 inch plates cut styling time on long thick hair
- 20 million negative ions tame frizz and static
- steady PTC heat with no hot spots
- temperature memory recalls your last setting
Cons
- Wide body makes it hard to grab hair near the scalp
- a few reports of units stopping after a few months
Frizz is the specific problem here, and negative ions are the specific answer. The 3D floating ceramic plates release 20 million negative ions per cubic centimetre, which neutralises static and helps smooth the cuticle rather than just pressing hair flat.
The 2-inch SuperMax lengthened design covers a lot of hair per clamp. PTC heating keeps a constant, stable temperature instead of cycling, and at one pound it is surprisingly light for a plate this wide.
Buyers like the gentle glide, with no hair pulling reported, and hair comes out soft and shiny. Five settings run from 320F to 460F with temperature memory, so the highest setting here is hotter than anything else on this list.
The main reported weakness is durability. A small number of reviews describe units that stopped working after a few months of use, which is a pattern worth taking seriously before you commit your money to it.
Who this is for
This is the pick if frizz is what actually bothers you. On thick hair that puffs up in humidity, the ion output does more visible work than the plate width alone.
It is also a strong budget option for anyone who wants the widest plates and the highest top temperature available here.
Who should skip it
Skip it if you need a tool you can rely on for years without thinking about it. Some buyers have had early failures.
Anyone doing root work will want a narrower companion iron, because a 2-inch body is difficult to angle at the scalp.
7. BaBylissPRO Nano Titanium Ultra-Sleek – Best for Quick Daily Styling
BaBylissPRO The Ultra Sleek Flat Iron, Nano Titanium, 1.5″
Full-floating nano titanium plates
Up to 450F
5 settings with LED display
Pros
- Heats in under a minute and smooths thicker textures in fewer passes
- even nano titanium heat reduces hot spots
- plates glide without tugging
- lightweight and easy to handle
Cons
- Exterior and plates get hot enough to burn fingers
- some reviewers need more than one pass
- a few describe the build as feeling cheap
This is the lighter, faster sibling to our premium pick. The ceramic heater gives instant heat-up with fast heat recovery, so the iron is ready quickly and recovers temperature the moment you hit a dense section.
Full-floating nano titanium plates glide without pulling, and reviewers rate the shine and frizz reduction highly. Many say it outperforms tools that cost considerably more.
Five digital settings with an LED display cover up to 450F, and a 9-foot professional swivel cord means you are not fighting the cable. A limited 2-year warranty is included.
Two cautions. The exterior and plates run hot enough to burn fingers if you touch them carelessly, and some reviewers find they still need a second pass on very thick hair.
Who this is for
This suits daily styling on medium-to-thick hair where you want fast heat-up and a light tool. At 1.15 pounds it disappears in the hand during a long session.
It is also a good second iron for someone who needs high heat at the top setting but gentle everyday results lower down.
Who should skip it
Skip it if your hair is extremely dense and you are set on a single pass. Narrower plates and a single-pass claim do not always go together.
If build quality perception matters to you, a few reviewers describe the construction as feeling cheap for the money.
8. 7MAGIC Nano Titanium 1.7 Inch Flat Iron – Best for Travel and Damp Styling
7MAGIC Nano Titanium 1.7″ Flat Iron Hair Straightener for Thick Hair, Blue
1.7 inch titanium plates
15 to 30 second heat-up
5 settings to 450F
Pros
- 1.7 inch plates engineered for thick and coarse hair
- heats in 15 to 30 seconds with instant recovery
- 3D floating plates adapt to hair thickness
- steam vents allow damp-to-dry styling
- dual voltage and 60 minute auto shutoff
Cons
- Side wheel temperature control is less precise than a digital display
- basic colour options only
This one is built around the thick-hair problem explicitly, and the 1.7-inch titanium plates are marketed for thick, long, coarse and curly textures. MCH heating gets to temperature in 15 to 30 seconds with instant heat recovery.
The steam vents are the interesting feature. They release moisture so you can go from damp to dry in a single pass, and reviewers report that it cuts frizz rather than sealing it in.
At 1.1 pounds with dual 110-220V voltage, a 360-degree swivel cord and a 60-minute auto shutoff, this is the most travel-ready tool in the list.
The side wheel control is the compromise. Five settings from 290F to 450F are reachable, but a wheel gives less certainty than an LED display, and users who need to know exactly what temperature they are on should look elsewhere.
Who this is for
This suits people who travel with a straightener or who style on the go. Dual voltage and the fast heat-up handle hotel bathrooms and short morning windows.
It is also a good match if you want to go damp-to-dry without dedicating a separate blow-dry step.
Who should skip it
Skip it if precise temperature control matters. A side dial is a step down from the digital displays on several other picks here.
If you like having colour options, this one is basic.
9. Bcway 2.16 Inch Extra-Large Flat Iron – Best Wide Plate for Long Thick Hair
Bcway Professional Hair Straightener, 2.16” Extra-Large Floating Titanium Flat Iron, Anti-Static 30s Instant Heating Straightening Iron with 5 Adjustable for All Hair Types
2.16 inch floating titanium plates
5 settings from 248F to 450F
30 second heat-up
Pros
- Widest plates in the group cut passes needed on thick hair
- 3D floating titanium plates avoid pulling
- 30 second heat-up with even distribution
- five temperature options from 248F up
- safety lock with one-step controls
Cons
- Top setting is 450F
- lower than some rivals
- hair care mode needs your own keratin treatment
At 2.16 inches, these are the widest plates in this roundup, and on shoulder-length or longer thick hair that translates directly into fewer passes. It is the most time-efficient option here and sits at the budget end of the range.
The 3D floating titanium plates are designed to avoid pulling as they move through a dense section, and heat-up takes about 30 seconds with even distribution across the surface.
Five temperature settings step through 248F, 302F, 356F, 410F and 450F, with a safety lock and one-step power and temperature controls. A 360-degree swivel cord keeps the cable out of the way.
Two limitations. The ceiling is 450F, which some titanium rivals exceed, and the hair care mode only works if you are mixing your own keratin treatment into the plates.
Who this is for
If your hair is very long and very thick, and time is the reason you are reading this, this is the pick. Nothing else on the list moves the same amount of hair per clamp.
It is also worth considering if you want a second iron for occasional heavy-duty sessions while keeping a lighter one for daily use.
Who should skip it
Skip it if you need to hit very high temperatures. The 450F ceiling is modest for 4a-4c textures that often want more.
Anyone who styles close to the roots daily will find 2.16 inches nearly unusable at the scalp.
10. ANNLARY 1.75 Inch Flat Iron with Infrared and Ionic – Best Budget One-Pass Iron
ANNLARY Hair Straightener, 1.75 Inch Flat Iron with Infrared and Ionic Technology, Titanium Plate with Ceramic Coating Dual Voltage Straightener with Heat-Resistant Silicone for All Hair Types
1.75 inch titanium-ceramic plates
Infrared plus 40 million ions
8 settings to 450F
Pros
- Reaches working temperature in about 10 to 20 seconds
- single-pass results on thick and 4C hair
- lightest-feeling body for long sessions
- LED display with 8 settings and a lock
- dual voltage with a glove included
Cons
- Can pull if sections are too large
- slight odour during initial use
- shorter cord than many competitors
- some plates narrower than listed
Infrared plus 40 million negative ions on 1.75-inch titanium plates with a ceramic coating, and a PTC heating system that starts heating in three seconds and reaches full temperature in about twenty.
Owners of thick, curly and textured hair call this a genuine one-pass straightener. Infrared locks in moisture while the ions neutralise static, which is the combination that keeps a thick head of hair from puffing up the next day.
It is also described as the lightest-feeling iron in this group, which matters a great deal on long thick hair. Eight LED-display settings run from 320F to 450F with a lock for storage.
Reported drawbacks are mostly small. Some users notice a slight odour on a new unit, the cord is shorter than many competing irons ship, and a few describe the plates as narrower than the listed 1.75 inches.
Who this is for
This is the pick if you want the least effort for the least money. Fast heat-up, one-pass results on textured hair and a light body for long sessions is a rare combination at this price.
It suits textured and black hair especially well, where the infrared and ionic pairing helps hold moisture through the style.
Who should skip it
Skip it if you take very large sections. Pulling at the hair is the reported issue, and it disappears when you use a narrower section than feels necessary.
If cord length matters to your setup, measure your space first, because this one runs short.
How to Choose a Hair Straightener for Thick Hair
Two attributes decide nearly everything on thick hair: how wide the plates are and what they are made of. Get those right and the rest is preference. Ignore them and you will be doing four passes over the same strand until it breaks.
Reddit consensus consistently favours titanium plates for coarse and curly hair, and users on r/Ulta praise the fast, even heat that cuts styling time on dense hair. That is a fair read, but it comes with a caveat that almost nobody mentions. The same discussions note that titanium is harsher on fine strands.
Ceramic vs titanium vs tourmaline for thick hair
Ceramic warms evenly and distributes heat gently, which makes it the safer choice for fine, dry or previously damaged hair. It produces shine, and infused versions add argan oil or keratin to the surface for an even softer finish. On thick hair it works, but it takes slightly longer to push through dense curls.
Titanium reaches a higher temperature faster and holds it without dropping, which is exactly why it is the standard choice for coarse and curly hair. The trade-off is that it transfers heat more aggressively, so it needs heat protectant and a lower setting if your hair is fine.
Titanium-ceramic blends, like the ones on our top rated wide-plate pick, sit between the two. Ionic coatings such as the 20-million-anion plates on our frizz pick add another layer, since negative ions help neutralise static rather than just pressing it flat.
Plate width: the single biggest factor on thick hair
Wide plates are better for thick hair, and the effect is bigger than most buyers expect. A 1-inch iron on long dense hair might take five or six passes to finish a section. A 1.75-inch or 2-inch iron can do the same section in two, and each pass you remove is a pass where you are not re-heating an already damaged strand.
The compromise is precision. Once you are past 1.75 inches, root access gets awkward and fine styling becomes impossible. Many people solve this with two tools: a wide iron for the body and length, and a narrower one for the roots and any waves.
Temperature settings: a recipe by hair type
Coarse and black hair typically wants the higher end of the range, around 400F to 450F, because the density resists lower heat and just comes out half-straight. Thick but fine hair works better in the middle, roughly 350F to 400F.
Dry, damaged or colour-treated hair belongs at 300F to 350F with plenty of protectant, and heat-damaged ends should never be pulled through a hot iron at all. Our wide-plate picks that go to 450F all have low settings too, and the Bcway even starts at 248F.
A digital display is worth paying for if you style more than one texture. Side wheels are fine when you always use the same setting, and confusing temperature readings are a complaint we saw repeatedly.
How to straighten thick hair in fewer passes
Dry the hair fully first unless your iron is specifically vented for damp styling. Applying heat protectant on damp hair dilutes it and reduces its effectiveness.
Work from the back of your head forward, in sections roughly an inch and a half thick. Clamp near the root but not on the scalp, then take one slow pass from root to tip without stopping. Never hold the iron in place or go over the same section twice out of impatience.
Let each section cool down completely before you move on, because the hydrogen bonds in the cortex reset as the hair cools. Skipping the cool-down is the most common reason results look great for ten minutes and then relax.
Low-damage and damage-avoidance options
If your hair is already damaged or you are straightening frequently, material choice matters more than width. Ceramic and infrared-equipped plates reduce the surface temperature your strand actually experiences.
Steam and vented designs are the other route. They release moisture rather than boiling it away, and owners of thick hair report less frizz when they go damp-to-dry instead of blow-drying first.
What people actually report back
The pattern in owner feedback is consistent across every category. Wide plates reduce styling time, titanium reduces the number of passes, ceramic increases shine, and the failure points are always the same: hot exterior plates, buttons bumped while gripping, and irons that need regular cleaning.
One r/beauty user reported that a budget Remington outperformed a straightener costing several times more, and that it had lasted nearly a decade. Others in the same discussions describe switching to a BaBylissPRO nano titanium on the recommendation of Ulta shoppers, which suggests brand loyalty is less useful than plate width in this category.
One more practical note before you commit to any of these: if long hair is only part of the cleaning burden, our robot vacuum picks for pet hair cover the same hair-collection problem on the floor rather than on your head.
Frequently Asked Questions
What is the best hair straightener for thick hair?
The best hair straightener for thick hair is one with plates at least 1.75 inches wide and a maximum temperature of 400F to 450F. Wide plates let you smooth a full section of dense hair in one or two passes instead of five, which is where most heat damage comes from. Our top pick pairs 2-inch argan-infused ceramic plates with a 450F turbo mode.
Is ceramic or titanium better for thick hair?
Titanium is better for thick, coarse and curly hair because it reaches a higher temperature faster and holds it without dropping, so dense curls smooth in fewer passes. Ceramic is gentler and shinier, making it the better choice for fine, dry or damaged strands. Titanium-ceramic blends give you a middle ground if your hair sits between the two.
Are wide plates better for thick hair?
Yes. Wide plates from 1.75 inches up are better for thick hair because each pass covers more hair, cutting the number of times a strand is re-heated. The trade-off is precision: plates wider than about 1.75 inches are awkward close to the scalp and impossible to use for tight curls, so many people keep a narrow iron for roots.
What temperature setting should I use for thick hair?
Coarse, curly or black hair generally works best between 400F and 450F. Thick but fine hair sits better in the 350F to 400F range, and dry or colour-treated hair should stay between 300F and 350F with heat protectant. Always apply protectant to damp hair, then dry it fully, unless your iron is vented for damp styling.
Which straightener is least damaging to hair?
Ceramic and infrared-equipped irons are the least damaging, because they spread heat gently across the strand rather than searing it. The other half of the answer is technique: one slow pass per section, never re-heating the same strand, and letting each section cool before you move on. Damage comes mostly from repetition, not from temperature alone.
How do I straighten thick hair without damaging it?
Use heat protectant on damp hair and dry it fully, then work in sections about an inch and a half thick. Clamp close to the root without touching the scalp and take one slow root-to-tip pass. Let each section cool completely before releasing it, since the bonds in the hair reset as it cools, and skip any section that is already straight.
The Verdict for Thick Hair in 2026
The best hair straighteners for thick hair in 2026 all share one trait: plates wide enough that you are not making five passes over the same section. The Remington Shine Therapy with its 2-inch ceramic plates is the pick for most people, because the width halves your styling time and the argan and keratin infusion delivers the shine that titanium irons tend to miss.
Go titanium and narrower if your hair is truly coarse and you want fewer, faster passes. Go vented and damp-to-dry if blow-drying is the part you hate most. Whatever you choose, one slow pass per section and a full cool-down will do more for your hair than any temperature number.
We test and update these picks through the year, so check back as new models land. If you also care about tools that handle heavy, dense jobs, our thick brush string trimmer guide covers the same wide-versus-narrow thinking.
