The 11 Best Flat Irons on Amazon, Starting at Just $21

Remington Shine Therapy 1 inch Hair Straightener Iron ($21, originally $30)

Good luck beating the price of this $21 straightener. The ceramic plates on this flat iron are infused with argan oil, keratin, and a "micro conditioner" to enhance shine and smooth frizz. Its 1-inch design doubles as the perfect curling iron size. (Because yes, it's entirely possible to curl your hair with a straightener). It has over 5,000 reviews and a 4.6 rating, making it a solid choice — especially for the price!

Bekind Apex 2-in-1 Hair Straightener ($28, originally $40)

This flat iron will let you straighten and curl all in one tool. It has a fast heating time of 15 seconds and adjustable temperature settings. The temperature memory function enables auto heat-up to the exact temperature that you last used it.

Vanessa Flat Iron Hair Straightener and Curler ($38, originally $40)

For curls, waves, or sleek straight hair, style with ease with this flat iron. If you prefer titanium-plated flat irons over ceramic-plated ones, give this a try. For those deciding between the two, many opt for titanium due to its fast heat-up time, lightweight design, and the way it glides smoothly through hair.

CHI Original Flat Hair Straightening Ceramic Iron ($47, originally $50)

If you love the look of sleek and smooth hair, you can't go wrong with this flat iron. It heats up to around 390 degrees Fahrenheit. It has one-inch floating ceramic plates, perfect for getting every inch of your hair, from hard-to-reach places to your roots. You can even create curls and flips with it. Many Amazon shoppers note that their hairstylist recommended it and are glad they took their word for it.

Hot Tools Professional Micro-Shine Flat Iron ($66, originally $120)

For a high-quality option that will last you for years, consider this flat iron. Customers love its versatility; it can smooth hair, create curls, form beach waves, create pin curls, and flip the ends. The soft-touch finish provides comfortable grip, and it has universal dual voltage, which is great for travel.

BaBylissPRO Nano Titanium 1" Ultra-Thin Straightening Iron ($160)

From the roots to the ends, get every inch of your hair with this flat iron. The high heat levels provide excellent straightening results while Nano Titanium technology protects hair from damage.

T3 Smooth ID 1" Flat Iron with Touch Interface ($249)

This flat iron takes hairstyling to the year 3000 with its interactive HeatID technology. It has the ability to personalize nine heat settings to your hair type with a touch of the screen, ensuring optimal heat for smooth styles in one pass. Customize your settings according to your hair type and texture, color treatment, and more.

GHD Chronos Styler ($329)

This flat iron claims to be a single-stroke styler, with the ability to straighten hair faster with even more shine. If you prefer to add waves or even curls, that's possible with this tool as well. Our editor owned GHD's older version and was skeptical about whether or not this new model would make much of a difference. Read all about her experience with GHD's latest styler in our GHD Chronos Styler review.

Editor quote: "I also have frizzy hair, and I've found that using this to go over my hair, even if I've curled it using a different styler, greatly helps to cut down on excess frizz. It's also easy to use: it glides through my hair like butter, and it leaves my hair with a sleek, glossy finish." — Renee Rodriguez, staff writer and social producer

GHD Duet Style ($399)

This hair tool is a two-in-one dryer-straightener hybrid. It works similarly to the Dyson Airstrait in that you can use it on wet hair to save time styling and conserve precious storage. Unlike the Dyson, it does use heated styling plates, so that's a factor to consider when weighing the pros and cons. Nonetheless, it has its fair share of fans, one of whom is a POPSUGAR social producer. Learn more about her experience using it via her comprehensive review of the GHD Duet Style.

Editor Quote: "The most important thing for me in any styling product is the time-saving aspect. With the GHD Duet Style, not only can I go from sopping wet to styled hair in the time it takes to watch half an episode of "The Office," the results actually lasted. Even though the tool offers the shine shot functionality, which the brand advises using on second-day hair, I really didn't need it. My hair stayed stick-straight for at least two to three days after the initial use." — Chloe Dunn, social content producer

Dyson Airstrait Straightener ($499)

All of Dyson's hair innovations are super high-tech, and the Airstrait Straightener is no exception. It dries and straightens wet hair using a proprietary airflow system — not hot plates, like many other brands. It's ideal for those looking to streamline their beauty routine and prevent hair damage. It comes highly rated by our senior beauty editor, who deemed it worth the investment. Read more in our Dyson Airstrait Straightener review.

Editor Quote: "I found it easy to work in pretty large sections of hair — roughly two-inch pieces — and didn't experience any snags or knots. The Airstrait actually detangled hair in the process of drying it. My final result was silky-smooth hair with lots of shine that felt healthy (as opposed to fried)." — Jessica Harrington, senior beauty editor

Dyson Corrale Styler Straightener ($499)

If you're looking for the ease and flexibility of a cordless option, Dyson's Corrale Straightener is worth considering. It gives up to 30 minutes of straightening time and takes 70 minutes to fully charge. The flexing plates help to better grip hair so that you can have shiny, smooth, and straight hair in less time with minimal damage. After discovering that this flat iron is Hailey Bieber's go-to hair tool, our editor decided to put it to the test. For more details and before and after photos, check out this Dyson Corrale Styler Straightener review.

Editor Quote: "What really set this product apart from other straighteners I've tried was the fact that it straightened all of the kinks and bends out of my air-dried hair without sacrificing volume. I was also able to bring it with me on a quick overnight vacation sans charging dock, which was such a huge plus." — RR
