    Anjou 1 Inch Curling Iron

    Most Versatile
    Anjou

    1 Inch Curling Iron

    Pros

    A simple and thoughtful design
    Digital display
    Safety features

    Cons

    Power delay

    Why we chose it

    Simple and thoughtful design

    Thoughtful extras greet you when you open the Anjou box, like a heat-resistant glove — which inexperienced users especially appreciated — and clips for separating hair into manageable portions. The iron itself radiates femininity through a pearly rose and black finish but stops itself from going overboard with minimalistic buttons that blend neatly into the handle’s design. Even the cord adopts an “I’ve got you covered” vibe, with a thick black-matte coating that prevents it from twisting into awkward knots and an attached velcro strap for storage.

    Digital display

    The biggest standout was the Anjou’s digital display — a frustratingly rare feature — that keeps no secrets when it comes to heat and lets you track temperature from the second you turn it on. This elevated the Anjou amidst a sea of vague dials and confusing systems that had us reaching for instruction manuals to determine exact temperatures.

    Safety features

    The Anjou left even the most paranoid testers feeling comfortable. It has the standard cool tip and kickstand to protect you and your counter from its heat, plus that heat-resistant glove and a 30-minute auto shut-off — a feature that’ll soothe any “did I leave my iron on?” anxiety after you leave the house.

    Points to consider

    Power delay

    Early on, we uncovered one flaw: the power button that takes an abnormally long press to turn on. You may even think the device is broken if you’re expecting an instant-on. Most testers figured this out after a bit of experimenting, though, and the extra-long press became second nature in no time. It’s easily forgivable at just $24.

    Hot Tools 24k Gold Curling Iron

    Best for Fine Hair
    Hot Tools

    24k Gold Curling Iron

    Pros

    Reputation
    Great results

    Cons

    A few features missing
    Creases in coarse hair

    Why we chose it

    Reputation

    Nearly every tester who got their hands on the Hot Tools said something like, “I think my hair stylist has this” or “Oh, my mom had this when I was growing up.” It’s no secret that Hot Tools’ gold-plated barrels are a hair styling mainstay; when you use one, there’s an inherent feeling of familiarity that other brands can’t quite match. The company’s years of experience shine in details like its easy-to-hold cool tip, soft matte handle, and durable cord (nearly identical to the Anjou cord we fell in love with). It’s a solid option to consider, especially if you are most comfortable buying from a time-tested, recognizable brand.

    Great results

    Most testers were pleased with the consistently shiny and smooth tendrils the iron left in its wake, and they felt like the grippiness of the gold gave them complete control over their curls. This held especially true for fine-haired testers, whose hair was at risk of slipping out of the clamp of ceramic picks like the Anjou. A few testers also said they preferred the curls from the Hot Tools iron over those from our top pick, Anjou, though, truthfully, the difference was too subtle for us to pinpoint.

    Points to consider

    A few features missing

    Setting an exact temperature is tricky with the Hot Tools; instead of the Anjou’s precise digital display, the Hot Tools uses a temperature dial with only a few set increments. The minor annoyance gets leveled up by a lack of indication that the iron has reached the desired temperature. It’s also the only one of our top picks that’s missing the nice-to-have auto shut-off safety feature. That wasn’t a deal breaker, but it did give the Anjou an edge.

    Creases in coarse hair

    Some testers — particularly those with fine hair — found that the Hot Tools’ clamp and grippy gold surface held hair at the perfect strength. However, others with coarser hair found it entirely too tight, leaving them with a few creases. Another pass could typically solve this issue, but one of our criteria for a top-of-the-line iron was that it should produce shiny curls in one go.

    Remington

    CI9538 T Studio Pearl Ceramic Curling Wand

    Pros

    Great beachy waves
    Intuitive

    Cons

    A slippery shape

    Why we chose it

    Great beachy waves

    Either of our top clamp iron picks can function as a wand by leaving the barrel closed, but some people prefer the streamlined simplicity of a tapered wand that will consistently produce natural-looking waves. Enter the Remington Pearl.

    One tester reiterated a few times just how much she loved the perfect, cascading waves this hair curler put in her mane. When it came to delivering shiny, natural looking waves, the Pearl was consistent and unbeatable.

    Intuitive

    The bubblegum-pink and eggplant-purple scheme makes the Pearl an exceptionally girly wand, which testers found charming. Pretty colors aside, the wand itself isn’t anything fancy, but that’s what hair wands are all about: no frills and no unnecessary parts (read: clamps) if all you want is waves.

    Much of the Pearl’s intuitive simplicity lives in its heat settings and buttons. The ever-transparent digital display was easy to adjust and didn’t make things more complicated than they had to be. When compared to the Conair Infiniti Pro wand’s five-setting system, this was an easy win.

    Points to consider

    A slippery shape

    The one complaint that came up for testers was that the shape of the Pearl (and every tapered ceramic wand) immediately directs hair to the thinnest part of the barrel. The tool is a bit slippery and it may take a few tries to twirl your hair around it. Compared to the similarly designed Conair Infiniti Pro, though, testers reported this one as less slippery and easier to handle, and testers found the results ultimately worth the effort.

    Beachwaver Co S1

    Best Automated Curler
    Beachwaver Co.

    S1

    Pros

    Easy to use
    Automated everything
    Curls of every kind

    Cons

    A spendy splurge

    Why we chose it

    Easy to use

    This much-buzzed-about, as-seen-on-TV Beachwaver tipped the scales from gimmicky to genius the moment we unclamped the first curl. We expected a knot-ridden ordeal but got a device that was hard to pry out of the hands of even the most low-maintenance testers. After comparing it to the more expensive Beachwaver Pro and CHI ARC Automatic Rotating Curler, both of which were strikingly similar in philosophy and design, this one came out on top as a true MVC (Most Valuable Curler). If you’re a newbie to curling who wants to bypass the learning curve or an everyday curler looking to save time, this over-$100 splurge is worth considering.

    Automated everything

    The S1’s home button (missing from the Beachwaver Pro) automatically brings the clamp back to a usable position after each curl and was crucial in helping our testers feel like they were in control. And while the Pro has a covert way of letting you change the barrel’s rotation speed (you have to read the instructions to find out how), the S1’s simple “fast/slow” slider makes it even easier to adjust. The large, easy-to-find control buttons on the S1 were also much-preferred over those of the CHI and the Beachwaver Pro, both of which had testers accidentally hitting buttons and turning the barrel the wrong way. That may not sound like a huge deal, but one tester cited it as the culprit for a panic-induced scalp burn.

    Curls of every kind

    An unexpected perk we found in automatic rotating barrel irons in general is their sheer versatility. We guessed that they were a one-trick pony with their fancy tech and robo-stylist vibe, but we were pleasantly surprised to learn that they can produce their consistent results in the form of “defined curls,” “loose beachy waves,” and “glam waves,” depending on how you hold the iron (check out Beachwaver’s YouTube tutorial for proof).

    Beachwaver for Curling Iron

    Points to consider

    A spendy splurge

    Our top pick, the Anjou, offers the same versatility at a quarter of the Beachwaver’s $103 price tag. This is the time-saving tool worth shelling out for if you’re looking to fully automate your curling experience, but if you’re keeping your styling simple, it’s overkill.

    How We Chose the Best Curling Irons

    Safety

    In order to keep your curled hair shiny and strong, two things about your iron matter: heat and the metal that’s conducting it. To strike a balance of style and safety, a curling iron should put you in control of its temperature and give you the ability to gradually find the heat setting that’s right for you and your locks.

    The ideal type of a metal for a curling iron isn’t quite so clear-cut. Some stylists we spoke with prefer titanium, while others mentioned gold-plating as a passable option. But there was one thing they could all agree on: Ceramic rules. Why? Some stylists told us that ceramic heats more evenly than any other metal, while others reasoned that its slippery surface means less tugging and tearing on hair strands that are already vulnerable due to heat.

    But while ceramic is clearly the cream of the crop, no expert drew a hard line saying it’s the only option. We focused our search on irons made of any material our experts told us is safe for hair (ceramic, titanium, and gold-plated) but kept in mind the extra benefits of using ceramic.

    Reputation

    For such a straightforward styling tool, there are a lot of curling irons out there. Finding the best meant cutting through the noise and narrowing the field to only the truly buzz-worthy. We pored over “best of” lists on beauty websites like ELLE and Allure, plus Amazon’s bestseller list, to find the irons that have the most people talking and are made of expert-approved materials. Then, to be sure we weren’t missing any super-popular brands, we called on expert stylists for their recommendations, which added BaByliss and CHI to the ranks.

    Accuracy

    We set all 15 irons to 350 degrees F and used an infrared thermometer to test their temperature truthfulness.

    Fourteen of the irons passed (we allowed them to bounce within 25 degrees above or below their stated temperatures), but one failed: the elegant, luxe, and much-acclaimed T3 Whirl Trio Interchangeable Styling Wand. No matter how many times we tested it or how many settings we tried, the iron’s temperature consistently rose to a full 75 degrees hotter than it claimed. At its highest setting (stated as 410 degrees F), the T3 heated up beyond the decomposition point of hair (465 degrees F). Yikes. While we can’t say that every T3 is so far off, we were forced to leave our model behind.

    As gorgeous as the T3 looked, its heat accuracy left much to be desired.

    Usability

    To find the best curlers, we looked for:

    • Buttons and setting features that are intuitive to use when you need them and out of the way when you don’t
    • Convenient safety features
    • The ability to produce shiny, frizz-less waves or curls in one pass
    • A clamp that’s not too tight (hello, creases) and not too loose (ugh, slippage)

    We had testers with different hair types, hair lengths, and curling experience levels produce a few curls to see if our finalists could check every box. By the end of it all, a few winners separated themselves from the rest.

    Guide to Curling Irons

    How to use your iron and curl your hair

    Keep temperatures on the safe side

    In terms of temperature, lower is better. According to Dr. Trefor Evans, Director of Research at TRI Princeton, curling enthusiasts run into trouble because cranking up the heat often means better curls, but it also means more damage (AKA frizz, breakage, and puffiness galore). You’ll find tons of resources online that’ll guide you to your ideal temperature range based on hair type, but we found those to be pretty inconsistent. Rather than adding another confusing chart to the mix, this advice from Dr. Evans is refreshingly obvious and works for any hair type:

    “Start at a low temperature, then work up to the minimum possible heat setting it takes to achieve a curl.”


    Extra hold comes from product

    If your curls aren’t holding very long, try adding hairspray or curling product. Expert stylist Kylie Harris gave us this hack: Spray your hair with sea salt spray and let it dry before beginning your routine. The grit helps your hair retain its new shape.

    Stay frizz-free by protecting your hair

    No matter how much we force them together, heat and hair will never be friends. But we have a few tips from the pros for minimizing heat’s frizzifying effects (or at least masking them).

    • Never curl wet hair. That’s crazy damaging, and experts are quick to confirm that fact. But here’s a real head-scratcher: Some irons are advertised as “wet/dry.” Don’t fall for it! Despite those advertisements, you’ll usually find fine print that says something like “don’t use on wet hair.”
    • Always use a thermal protectant. And let it dry before you apply any heat. Brands that were recommended by our pros include Joico, Mizani, Oribe, and Leonor Greyl.
    • Use a good conditioner. Dr. Evans gave us this analogy: “The surface of hair is like tiles on the roof of a house. The structure gradually gets beaten up over time. Tugging makes those scales stand up.” While that damage can’t be undone, Dr. Evans advised that conditioner can at least smooth over those tiles and hide the evidence.
