When you feel like it’s time for straight, shiny locks, we’ve got your back. Our flat irons are so well-designed and powerful they can straighten even the curliest of hair. Our selection of hair straighteners also come in a variety of sizes, colors and shapes, and some even include thermal bags or travel containers so the flat iron is protected. Many of our irons also include a warranty to guarantee that the electronic components are functional for years to come. Depending on how long or short your hair is, or the type of styles you seek, you will need to select a style that best suits your styling needs. For instance, a 1.5-inch iron works best on medium to long hair, while 1-inch irons are typically made for shorter hair.
Most mid-grade and high-end hair straighteners come with plates that are 1” or 1.5”. If you are looking at one that is 2”, 2.5”, or even bigger, steer clear immediately. Not only does larger plates make it easier for you to accidentally over-iron (and seriously damage) your hair, but they also make it more difficult to get all of the way down to your roots. For anyone with type 3 or type 4 hair, trying to use a large-sized flat iron would be far more trouble than it’s worth.
Many hair straighteners feature a visual interface to alert you when the device is getting a bit too hot for comfort or when it has surpassed the ideal temperature for your hair. With the T3 Micro Single Pass Flat Iron, you can expect the same visual cues with the bonus of sound alerts as well! That’s right; this flat iron will actually tell you when it reaches its ideal temperature or when it is about to shut off automatically after one hour. Now that’s some hot tech!
Heat protectants contain ingredients that coat hair and slow down heat induction. Janine Jarman says, “Blow dry your hair properly; use a heat protectant product; and with the right iron, you should not have to make a bunch of passes to get the results you want.” We used TRESemmé Expert Selection Heat Protection Spray, Keratin Smooth. Most of our testers liked how it worked on their hair and felt a noticeable difference when using it. Our tester with kinky hair didn’t use the product because she knew it wouldn’t work on her hair. Instead, she recommends using an oil (like an Argan oil) or a hair grease to add moisture to the hair, which makes it easier to straighten.
【STEAM TECHNOLOGY】Creative Idea: Vapor, smoothes your hair during the styling process, adds moisture and gloss to your hair. NO MORE FUZZY! Please note that, the steam will only comes out when you clamp on the flat iron. if there are no steam comes out, please check if you have TURN ON the STEAM BUTTON and refer to the user manual of the "STEAM RELEASE SETTING" for reference if needed. Plese note that ONLY WATER could be added to the water tank,NO OIL or other liquid added.
In addition to a fast heat-up time and multiple temperature settings, the 9-foot cord and 360 swivel make for easier styling and prevents and tangling. You can also travel with this styling iron thanks to the dual voltage settings. Anti-slip edges and floating plates allow your hair to glide effortlessly between the plates, with no pulling or snagging which can be especially damaging for fine hair.
This feature is particularly helpful if you have textured hair with waves or curls, which can become damaged so easily by heated styling tools. That said, it is not clear which heat setting is ideal for users with thick or somewhat straight hair. This may make this slightly more difficult if you are using a flat iron for curling purposes or if you need to straighten an especially thick head of hair each day! However, we are confident that a little tinkering is all it takes to find the perfect heat setting for these different hair types and styles, so you can rest assured that this hair straightener can still meet all your hair styling needs!

No two heads of hair are the same, so the straightener that does wonders on your best friend's fine tresses may be useless on your curly mane. Luckily, there are many different types of hair straighteners. Some provide higher heat settings and wide plates to tackle thick curly hair, and others have ceramic plates and options for low heat settings that are better suited to easily damaged fine hair.

When you apply heat to your hair, which is not a living thing, you’re essentially cooking it. And, just like food, it’s easy to overdo it. Short of actually searing your hair, you still run the risk of drying out each strand, which can lead to breakage and split ends over time. Every head of hair is different, and each type of hair has an optimal flat-iron temperature. Some locks need extremely high temperatures to relax — coarse hair or those with kinky hair need 380 degrees F or above. Others need hardly any heat at all — fine or damaged hair should be good below 300 degrees.


The glider plus is designed to protect your hair with integrated heat balance micro processors that continuously monitor the exact temperature across the surface of the plates and automatically adjust the temperature for evenly distributed heat. That means fewer passes are needed for silky results, while protecting your precious hair from over heat exposure.

We’ve all heard the saying that the grass is always greener on the other side, and our hair types tend to follow the same old adage. If you were born with a head full of beautiful curls, you probably spent your childhood longing for straight hair; if you were born with bone straight hair, then you’ve probably spent more hours than you’d care to admit with a throbbing curler-induced headache. No matter how hard we may try to love the hair we’re born with; the truth is that most of us wish there were something else perched on top of our heads from time to time.
I started this site after I made the decision to get a new hair straightener. I am not a novice with irons by any means, and I’ve had just about every kind imaginable except for some of the newest options. When I realized how far the industry had come in the last couple of years, I decided it was time to try something new. A good flat iron can last for years, as long as you look after it and make sure you buy one that’s robust enough to take what you put it through. By doing your homework up front, you can make sure you not only get the right straightener for your locks, but you don’t end up spending an inordinate amount of money on something that doesn’t work for you. Believe me, I’ve been there!
“This is a badass flat iron. Here’s the skinny: The moment you turn it on, it has a ‘Fragile, Damaged, Healthy’ setting, and it also auto-locks the buttons to keep what temperature you want while doing your hair. It comes with a professional bag for traveling with it. This flat iron is ‘pinky in the air while drinking your tea’ fancy. It is the Ferrari of flat irons, for a girl on a budget wanting a new flat iron. And for my fellow sistas: It works amazingly on African-American hair.”
Nearly 21,000 people gave this flat iron a five-star review on Amazon. If they factored price into that rating, then I agree. For less than $60 it’s pretty spectacular, but it doesn’t beat the fancier ones in terms of performance. The temperature automatically drops after 15 minutes of use. And while it’s easy to adjust that, it is also slightly inconvenient.
