Is a $190 Hair Straightener Really Worth It? I Tested It to Find Out (2024)

Is a $190 Hair Straightener Really Worth It? I Tested It to Find Out (1)

We've been independently researching and testing products for over 120 years. If you buy through our links, we may earn a commission. Learn more about our review process.

Hair dryer brushes and heated hair brushes are great, but nothing gives hair that sleek, glossy, mirror shine like a straightening iron. Finding a good flat iron that makes easy work of styling your hair without totally frying it in the process can be difficult — and unlike most beauty purchases, can run you a couple hundred dollars. Is pricier really better?

In the Good Housekeeping Institute Beauty Lab, we've tested more than 90 flat irons. To find the best picks for you, we tallied 2,013 heat data points from measurements taken in the Lab and results from 960 survey responses provided by our panel of at-home consumer testers.

In our tests, CHI's Lava Ceramic Hairstyling Iron and ghd's Platinum+ Professional Performance Styler earned the highest scores for their chart-topping performance and intuitive usage — but we were also wowed by budget-friendly picks from Remington, tried-and-true irons by BaByLiss and new, innovative favorites from T3 and Dyson. Before getting started, don't forget to coat hair with heat protectant and use the best hair products for your hair type to make easy work of straightening your hair.

    • Is a $190 Hair Straightener Really Worth It? I Tested It to Find Out (4)Top performance scores in Beauty Lab tests
    • Is a $190 Hair Straightener Really Worth It? I Tested It to Find Out (5)Top consumer satisfaction and ease of use scores

    Cons
    • Is a $190 Hair Straightener Really Worth It? I Tested It to Find Out (7)No audible alert once iron reaches temperature

    Speed-heating and power-smoothing, this CHI earned a rare perfect score with GH’s expert evaluators and was by far our top-tested flat iron. In tests, it warmed up to 96% of max temp in 60 seconds, although our pros wish there was an audible tone to indicate when it reaches temperature.

    Still, it ranked best in almost all categories, including fully straightening hair and keeping it sleek and frizz-free all day. It also got perfect marks from testers for gliding smoothly through hair and being easy to use, with all commenting on the "noticeable shine" in just one pass. "I really like how fast I was able to style my hair," said one tester, with another saying, "I would buy this product in a heartbeat."

    BEST VALUE

    HAIRITAGE Straight to It Flat Iron

    Is a $190 Hair Straightener Really Worth It? I Tested It to Find Out (8)

    Pros
    • Is a $190 Hair Straightener Really Worth It? I Tested It to Find Out (9)Budget-friendly
    • Is a $190 Hair Straightener Really Worth It? I Tested It to Find Out (10)Great weight and size
    • Is a $190 Hair Straightener Really Worth It? I Tested It to Find Out (11)Extra-long cord
    Cons
    • Is a $190 Hair Straightener Really Worth It? I Tested It to Find Out (12)Takes a while to heat up

    This under $40 stunner wowed us in Lab tests. Testers loved its size, rated it highly for being comfortable to hold and praised its controls too: "Good temperature setting options, lightweight, easy to hold and use." It has a super long cord, which is rare to find in this price bracket — the longer the cord, the easier it can be to style hair.

    It's a great value, but keep in mind that it took longer to heat up than other models we tested (more than two minutes), so be sure to power it up well before you start styling. Once it heats up, though, you'll love styling with it: "I was amazed at how easy it was to achieve a more sleek, put-together look," said one tester.

    BEST WET-TO-STRAIGHT

    Dyson Airstrait Straightener

    Is a $190 Hair Straightener Really Worth It? I Tested It to Find Out (13)

    Pros
    • Is a $190 Hair Straightener Really Worth It? I Tested It to Find Out (14)Less damaging to hair
    • Is a $190 Hair Straightener Really Worth It? I Tested It to Find Out (15)Offers wet and dry styling
    • Is a $190 Hair Straightener Really Worth It? I Tested It to Find Out (16)Super smooth, sleek results
    Cons
    • Is a $190 Hair Straightener Really Worth It? I Tested It to Find Out (17)Expensive
    • Is a $190 Hair Straightener Really Worth It? I Tested It to Find Out (18)Limited versatility

    A recent GH Beauty Award-winner, this innovative plate-free straightener uses high-pressure airflow to straighten hair as it dries, which the brand claims is less damaging to hair. The airflow is projected downwards at a 45° angle to mimic a super-smooth blowout and create the tension needed for a pin-straight finish in one step, even on curly hair (I tried it on my type 3 curls, below, and can confirm). It also has both wet and dry styling capabilities and features a setting that allows you to blow dry your roots without clamping down on strands.

    "This product completely transformed my damp hair into fully dry and straightened hair," said one tester. Since it operates at a much lower temperature than traditional flat irons, testers also appreciated that, "I was not concerned about burning my hair, face or neck." The resulting style, testers agreed, was noticeably shiny, smooth to the touch, sleek and styled. "After styling, my hair stayed straight and frizz-free all day."

    It doesn't come without drawbacks, though: First, it's extremely expensive at nearly $500. It's also a bit limited in its versatility since it only straightens hair and doesn't allow for much volume in the resulting style. And in my experience, it's a bit bulky to use and store. Still, if you religiously straighten your hair and are concerned about excessive heat damage, we think it could be a worthy investment

    Pros
    • Is a $190 Hair Straightener Really Worth It? I Tested It to Find Out (22)Maintains 365º to protect hair from damage
    • Is a $190 Hair Straightener Really Worth It? I Tested It to Find Out (23)Rounded edges are great for curling hair
    • Is a $190 Hair Straightener Really Worth It? I Tested It to Find Out (24)Comfortable to hold
    Cons
    • Is a $190 Hair Straightener Really Worth It? I Tested It to Find Out (25)No adjustable temperature
    • Is a $190 Hair Straightener Really Worth It? I Tested It to Find Out (26)Extremely expensive

    A standout in Lab tests, this top-performing iron maintained a consistent, steady temperature of 365º to protect hair from excessive heat damage and its technology ensures even heat across the entire plate, which means easier styling and more consistent results.

    Testers loved how it made their hair feel: "smooth, shiny and healthy without flyaways or frizz, just a perfectly straight look," although in our Lab tests, it had below average score for maintaining straightness when exposed to humidity for 24 hours. Still, it's a favorite of GH editors and several celebrity stylists we interviewed for this article. Mane Addicts stylist Sabrina Porsche says, "I recommend ghd irons for anyone who has natural hair and wants to use the best iron that won't damage your hair with heat."

    I use this iron on my own hair at home regularly, and I love how it glides through my hair like butter, making quick work of smoothing out kinks and frizz on my curly, thick hair. It makes my hair look glossier and shinier than any other hair tool ever has. Plus, the rounded plates make it easy to bend, wave and even curl hair.

    It got a perfect score among testers for being comfortable to hold, but the lack of adjustable temperature may be a turn-off for some (all of our testers noted they wished they could adjust the temperature), plus it lacks a temperature display. In a Lab test, we found that the flat iron heats up fast, reaching 99% of its claimed temperature in just 30 seconds. As with most innovative tools on the market, you get what you pay for — and this flat iron is extremely pricey at over $270. It's an investment, but one that could be healthier for your hair in the long run.

    Cons
    • Is a $190 Hair Straightener Really Worth It? I Tested It to Find Out (33)Pricey

    Boasting the widest temperature range of the flat irons we tested, this titanium straightener has settings spanning from 200ºF to 450ºF, which makes it a Swiss Army knife of stylers: it suits a wide range of styling needs and hair types.

    Testers loved how comfortable it was to use, praising its soft-touch surface and comfortable grip. "The finger grip on the top is excellent and I liked how fast the flat iron straightened my hair."

    It's on the pricier side, but one tester said they were "extremely satisfied with the way my hair looked afterwards," with another marveling at how "smooth" their hair felt. It also got a perfect score among testers for not burning their face, scalp or neck, even for those who said that's been "an issue I've had with other flat irons," making it a solid choice for those who aren't confident using a heat tool quite yet.

    BEST FOR LONG HAIR

    ELLA BELLA Ceramic Flat Iron

    Is a $190 Hair Straightener Really Worth It? I Tested It to Find Out (34)

    Pros
    • Is a $190 Hair Straightener Really Worth It? I Tested It to Find Out (35)Wider-than-average plates
    • Is a $190 Hair Straightener Really Worth It? I Tested It to Find Out (36)Top scores for not snagging hair
    • Is a $190 Hair Straightener Really Worth It? I Tested It to Find Out (37)Smooth, sleek results
    Cons
    • Is a $190 Hair Straightener Really Worth It? I Tested It to Find Out (38)Doesn't reach claimed temperature

    With wider-than-average plates at 1 3/8 inches, we love this flat iron for making quick work of smoothing out longer hair. Testers called it "the perfect size," saying the width of the plates made it easy "to do a lot of styles." It was also rated highly for not pulling or snagging on hair and got a perfect score among testers for being easy to open and close, although some wished the plates closed more tightly.

    One tester said, "my hair is very fine and dry, but I was really impressed with how smooth and shiny this flat iron made my hair." This pick is well-priced at under $100, but our Lab tests showed that the iron only heats up to 410ºF while on the 450ºF setting, so keep in mind that you may need to tinker with the temperature settings as you style to find the right level for your hair.

    BEST FOR FINE HAIR

    Is a $190 Hair Straightener Really Worth It? I Tested It to Find Out (39)

    Is a $190 Hair Straightener Really Worth It? I Tested It to Find Out (40)

    Pros
    • Is a $190 Hair Straightener Really Worth It? I Tested It to Find Out (41)Determines the best temperature for your hair type
    • Is a $190 Hair Straightener Really Worth It? I Tested It to Find Out (42)Creates long-lasting smooth styles
    • Is a $190 Hair Straightener Really Worth It? I Tested It to Find Out (43)Perfect score for consumer satisfaction
    Cons
    • Is a $190 Hair Straightener Really Worth It? I Tested It to Find Out (44)Buttons can be tricky

    Don't want to scorch your delicate strands? This iron eliminates the guesswork by selecting a temperature based on your hair type, with options for fine, medium and coarse. It also has a "curl mode" which lowers the temperature for creating curls, essential when the iron is moving more slowly through hair. "Far too many times, people use a hotter setting than they actually need," our Lab pros say, but with nine temperature settings, this iron has the perfect fit for everyone, meaning you won't scorch even super fine hair.

    It nabbed perfect scores among testers for consumer satisfaction and for straightening hair completely without burning or visibly damaging hair, with a tester saying, "I love, love, love that my hair stayed straight and did not frizz." Testers with fine hair also appreciated that it lives up to its name: "It heats up quickly, straightens in one go and for the most part lasts all day."

    Porsche says, "I love T3 because if I am doing a silk press, I know I am getting super straight and shiny results." The iron remembers your settings but also offers manual setup, although testers found the buttons tricky to use and wished it had a temperature display.

    MOST INNOVATIVE

    BaBylissPRO Studio Design Series Root Reacher

    Is a $190 Hair Straightener Really Worth It? I Tested It to Find Out (45)

    Pros
    • Is a $190 Hair Straightener Really Worth It? I Tested It to Find Out (46)Uniquely shaped plates to reach roots
    • Is a $190 Hair Straightener Really Worth It? I Tested It to Find Out (47)Broad temperature range
    • Is a $190 Hair Straightener Really Worth It? I Tested It to Find Out (48)Heats up quickly
    Cons
    • Is a $190 Hair Straightener Really Worth It? I Tested It to Find Out (49)Wide plates may not be great for short hair

    Uniquely designed, this flat iron features unusual teardrop-shaped plates that are designed to make it easier to straighten close to the root, perfect for pressing cowlicks and baby hairs on curly or frizzy hair nice and flat. Our pros appreciate the nice, long cord, and testers like that "it heats up quickly," and reaches "a high temp that is required for my coarse, wavy hair type." We also like the broad range of temperatures, from 260ºF to 450ºF.

    Its design is innovative, which can sometimes have a tricky learning curve, but testers rated the manual as most easy to understand. The plates are nice and wide, at 1.5 inches, which can make styling long hair a lot faster (although those with shorter hair may find the extra-wide plates unwieldy).

    Plate size: 1 1/2-inch | Temperature settings: 10 adjustable settings, 260ºF-450ºF | Auto shut-off: 60 minutes | Cord: 8.8 feet | Material: Ceramic

    BEST FOR THICK HAIR

    REVLON Salon Straightener Copper Smooth Flat Iron

    Is a $190 Hair Straightener Really Worth It? I Tested It to Find Out (51)

    Pros
    • Is a $190 Hair Straightener Really Worth It? I Tested It to Find Out (52)Super long plates
    • Is a $190 Hair Straightener Really Worth It? I Tested It to Find Out (53)Wide temperature range to suit many hair types
    • Is a $190 Hair Straightener Really Worth It? I Tested It to Find Out (54)Perfect for long, thick hair
    Cons
    • Is a $190 Hair Straightener Really Worth It? I Tested It to Find Out (55)No audible tone when it reaches temperature

    Revlon’s super long, 1-inch-wide tool gave lasting straightness to even the longest, thickest hair in our tests. It had the widest temp range (180°F to 455°F) in our tests and at 4.9 inches, the longest plate length we tested ("but not too long," said testers) which aided in "making the process quicker," a pro noted, especially on dense strands, although it does have a shorter-than-average cord.

    It took around a minute to reach 94% of its claimed temperature, but our pros were disappointed that there was no audible tone to indicate when it reaches temperature. It earned the top score for maintaining hair straightness in our technical test, though the lowest score for keeping hair straight, shiny and frizz-free all day long, according to consumer testers, so make sure you use an anti-frizz serum.

    BEST FOR FRIZZY HAIR

    Is a $190 Hair Straightener Really Worth It? I Tested It to Find Out (57)

    Pros
    • Is a $190 Hair Straightener Really Worth It? I Tested It to Find Out (58)Best scores for maintaining sleekness that lasts
    • Is a $190 Hair Straightener Really Worth It? I Tested It to Find Out (59)Budget-friendly
    • Is a $190 Hair Straightener Really Worth It? I Tested It to Find Out (60)Lightweight
    Cons
    • Is a $190 Hair Straightener Really Worth It? I Tested It to Find Out (61)Shorter-than-average cord

    Lightweight and bargain-priced, this Remington delivers smooth strands that stay in place. The tool was the lightest-weight of the winners in our most recent test (0.77 pounds!) and tied for best at maintaining sleekness. "One pass for effective straightening that lasted," an evaluator said, with another adding hair "felt soft and looked straight with this iron," perfect for even tough-to-manage frizzy hair.

    In Lab tests, it heated up to 93% of its claimed temperature in 60 seconds, which is speedy but not as fast as the 15 seconds claimed. Keep in mind it does have a narrow temperature range of 300-450°F, so it might not be suitable for thinner or fragile hair types, and the cord is shorter than average which can make styling cumbersome.

    BEST FOR CURLY HAIR

    BaBylissPRO Nano Ultra-Thin Straightening Iron

    Is a $190 Hair Straightener Really Worth It? I Tested It to Find Out (62)

    Pros
    • Is a $190 Hair Straightener Really Worth It? I Tested It to Find Out (63)Beauty Lab go-to
    • Is a $190 Hair Straightener Really Worth It? I Tested It to Find Out (64)Plates extend to iron's edge for smoothing frizzy hair

    Cons
    • Is a $190 Hair Straightener Really Worth It? I Tested It to Find Out (66)No auto shut-off
    • Is a $190 Hair Straightener Really Worth It? I Tested It to Find Out (67)Takes longer to heat up than other irons

    This iron is our Beauty Lab standard: We use it for various evaluations such as anti-frizz studies. It glides through hair without tugging and is easy to use according to consumer testers, though it does take a bit longer to heat up than other irons. Plus, with over 11,000 five-star reviews on Amazon, it's safe to say people are obsessed with this flat iron from BaBylissPRO.

    Because the titanium iron is so thin and the plates go all the way to the edge of the clamp, it's able to nab frizz right at the root of the hair, making this iron perfect for stubborn frizz or super-curly and natural hair. One Amazon reviewer who says she has "very, very curly hair," claims that this flat iron cuts her styling time in half and gets rid of frizz in one pass. Since there's no auto shut-off with this iron, you'll have to remember to unplug it after use for peace of mind.

    BEST CORDLESS

    Is a $190 Hair Straightener Really Worth It? I Tested It to Find Out (68)

    Is a $190 Hair Straightener Really Worth It? I Tested It to Find Out (69)

    Pros
    • Is a $190 Hair Straightener Really Worth It? I Tested It to Find Out (70)Can be used cordless or corded
    • Is a $190 Hair Straightener Really Worth It? I Tested It to Find Out (71)Flexing plates for voluminous yet sleek hair
    • Is a $190 Hair Straightener Really Worth It? I Tested It to Find Out (72)Heats up fast
    • Is a $190 Hair Straightener Really Worth It? I Tested It to Find Out (73)Hair retains volume and body
    Cons
    • Is a $190 Hair Straightener Really Worth It? I Tested It to Find Out (74)Heavy, bulky profile
    • Is a $190 Hair Straightener Really Worth It? I Tested It to Find Out (75)Narrow range of heat settings

    Perfect for travel (or inconveniently placed outlets in the bathroom), this Dyson flat iron can be used cord-free: The brand claims one 70-minute charge grants 30 minutes of cordless styling. Unlike traditional flat irons that have a solid surface, the Dyson's plates are flexible so hair doesn't get squished flat which "left [hair] a bit voluminous like a blowout" and a style that testers said "retained volume," yet "stayed straight and kept its body." It's heavy and bulky, but experts found that “it didn’t seem to matter during use.”

    From the operational standpoint, the Dyson excelled: It heated up to 95% of its claimed temperature in 60 seconds and maintained a steady plate temperature for 15 minutes, while the outside surface temperature stays cool to the touch. However, in Lab tests, hair struggled to maintain straightness after 24-hour humidity exposure, and our experts found it pulled and snagged hair more than other irons during styling.

    How we test flat irons

    Is a $190 Hair Straightener Really Worth It? I Tested It to Find Out (76)

    In the Good Housekeeping Institute Beauty Lab, we test and evaluate all types of hair tools, including straightening brushes, mini flat irons, straightening irons for natural hair and hair-smoothing hair dryer brushes, to find the ones that will give you the most gorgeous hair at the right price and performance. In our penultimate test of flat irons, we rounded up more than 50 products from over 20 manufacturers to find the best flat irons — and in our most recent test, we added 40 more.

    Is a $190 Hair Straightener Really Worth It? I Tested It to Find Out (77)

    Our product analysts start by assessing each iron's weight and size, ease of use and ability to impart shine and smooth hair. We also run tests to evaluate durability, safety and efficiency.

    For example, in the Lab, we take temperature readings of each iron's plate surface at its hottest setting to measure how quickly it heats up and maintains its temperature. We also measure the outer surfaces of each iron to ensure that it doesn't get too hot to the touch. We log the temperature at three spots on every iron every 10 seconds for 10 minutes, resulting in 183 temperature measurements for each iron.

    On top of all that, we also survey our proprietary consumer panel to get in-depth feedback from a wide range of people. In our latest test, we tallied up 2,013 heat data points and 960 consumer survey questions to find the best of the best.

    What to consider when shopping for the best hair straightener

    Is a $190 Hair Straightener Really Worth It? I Tested It to Find Out (78)

    Beyond material, "some of the aspects that make a great flat iron include the heating element ... a good visual digital thermometer, the quality of the plates and the length of the cord," says Toye. "The best flat irons are ones that sit comfortably in your hands, have an even heat distribution and selection of temperatures so that you don't damage your hair," adds Porsche.

    Here's what else to keep in mind:

    ✔️ Heat settings: A flat iron with multiple heat settings allows for more customization and flexibility when styling since you’re able to select a temperature that works for your hair type/needs. Our expert testers preferred having an option of a temperature range for their flat irons, and Hughes agrees: “It is a must for all hair types. Most irons go up to 430-450ºF,” but that doesn't mean you should crank up the heat all the way!"

    We recommend always starting off at a lower temperature and increase the temperature as needed since temperatures above 450ºF can cause decomposition of hair's protein content, causing irreparable damage. Although there is no scientific guidance on the best temperature ranges to use for different textures, our pros averaged all the temperature suggestions from manufacturers for fine, medium and thick, coarse hair:

    • Fine hair types should stick to 240-330°F
    • Medium hair types can style at 330-370°F
    • Thick, coarse hair can handle temps starting at 390°F and go up from there.

    ✔️ Plate width and length: "One-inch plates are ideal," says Hughes, since these narrower plates can make it easier to do detailed styling (like curling, bending or waving) and they’re also better for getting closer to the root of the hair. One exception: If hair is super long and you're just looking to press hair straight, a 1.5-inch or 2-inch width can make faster work of the task.

    ✔️ Cord length: If you’re planning on styling hair in a bathroom or close to an outlet, cord length might not be an issue, but if you don’t have an outlet by your mirror, you may want to opt for a longer (or “professional”) length. Cord length in our study varied from 5.6 to 10.8 feet, with an average of 8.1 feet — the longer the cord, the more convenience and range you’ll have. “Also, if the cord swivels, that is a great feature so you can move easier,” says Hughes.

    ✔️ Auto shut-off: “People are busy and we can all forget to turn off an iron when we are running late, so auto shut-off ensures you some peace of mind,” says Hughes. In our tests, auto shut-off varied from five minutes to two hours, which is handy when you can't quite remember if you turned the tool off — but we still recommend powering off and unplugging the tool after use to ensure it is completely off.

    What type of hair straightener do professionals use?

    Is a $190 Hair Straightener Really Worth It? I Tested It to Find Out (79)

    Some flat irons claim to prevent damage, and others claim to be made with the best material for a healthy shine, but as a shopper, it can be confusing to tell which is best.

    When it comes to material, professionals tend to favor titanium flat irons. "Titanium is preferred among stylists because [it tends] to get hot really quickly," says Eugene Toye, stylist at celebrity-favorite hair salon Rita Hazan. According to Porsche, titanium has even heat distribution, which makes for smooth, silky hair. "Titanium is ideal as a flat iron plate," agrees Kevin Hughes, celebrity stylist and artistic director for Moroccanoil. "It heats up quickly and is a very even heat, which translates to better results and less time go over the same strands of hair."

    Another great pick: ceramic or tourmaline. "These plates are safe for thin/fine hair and don't get extremely hot," says Porsche. "Most ceramic flat irons provide faster results in less time, meaning less heat on your hair." That said, our Beauty Lab pros have found great flat irons come in all sorts of materials, from ceramic to titanium and beyond, so don't get too caught up in material claims and focus on other important aspects like adjustable heat settings, cord length and budget.
