Here at the Strategist, we like to think of ourselves as crazy (in the good way) about the stuff we buy (like pillows), but as much as we’d like to, we can’t try everything. Which is why we have People’s Choice, in which we find the best-reviewed (that’s four-to-five-star reviews and lots of ‘em) products and single out the most convincing. While we’ve written about the best curling irons, hair dryers, and even a certain curling iron used on the Victoria’s Secret Angels, here, we’re going deep on the best flat irons and hair straighteners on Amazon. (Note that reviews have been edited for length and clarity.)
It becomes extremely hot – up to 392 degrees Fahrenheit, and it holds that heat until you shut it off. Because of this, you can straighten any type of hair with Chi, including very thick and coarse tresses. So if you have such hair, this iron could be your best option. It is not only designed to straighten but also to curl hair. Thanks to its ergonomic design, you won’t strain the hands and wrists during use.
The two strips of silicone atop Bio Ionic’s flat iron plates seem silly, but they serve an important purpose. By buffering the outer edge of the plates, they reduce your chances of hair snags. They also force you to glide the flat iron more slowly through your hair (they are called speed strips, after all). While the slower technique maximizes shininess and smoothness, the speed strips can become a bit of an obstacle if your hair is thick.
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.

While temperature control is typically a good thing to have in a hair straightener, it can also result in hair damage if you're keeping the temperature too high. The GHD Gold eliminates the chance of any user error, operating at an even 365 degrees Fahrenheit. This is the optimal temperature for most hair types, getting you smooth results without damaging your hair. The gold coated ceramic plates heat up quickly and maintain an even temperature, eliminating the chance for any hair damaging hot spots as well.

As one of the hottest hair straighteners we have reviewed (temperature-wise…although it is pretty to look at, we have to admit…), the Solano Sleek Heat 450 Professional Flat Iron can reach temperatures of up to 450° F in as little as 60 seconds! This Solano hair straightener also features thin 1 inch plates, making it an ideal choice for anyone with short or medium length hair and the quick heat time ensures that even the most stubborn of curls can be tackled with a little extra heat. If you are looking or something a little larger though, it is also available with 1.54-inch plates too.


If you are unsure what exactly your hair type is (or if it has changed over the years, which happens more often than you’d think!), check out this incredible overview by the hair professionals at Redken! Don’t stress if you have combination hair (i.e., fine and curly or thin and straight) either; we recommend choosing a hair straightener based on your biggest hair complaint and focusing on that problem first. So, if your curls are driving your nuts, you will want to select a hair straightener with higher temperatures, thin hair needs moisture, etc. You’ll find that your entire hair type can usually benefit from the extra TLC!

It comes with the most advanced heating element in this industry. Using a digital display, you can adjust temperature from 280F to 450F. This means that you can use it to style fine or very fragile hair as well as very thick and coarse. This is the model that is often recommended for women that have hair that is hard to straighten and difficult to keep straight. So if lower heats do not work for you, use the highest setting, and get pin straight results, like glass.

“I bought the HSI titanium tourmaline ionic flat iron and I was so impressed with it. It glides so smoothly down the hair without any tugs! The digital display screen lets me adjust the temperature without any problems, it heats up fast, and I love that it comes with a pretty purple pouch, glove, and argan-oil serum. I also own the digital HSI ceramic ionic flat iron from 2013, and it’s still going strong, but I do like the titanium iron better, and I see myself using for it for years to come. It leaves my hair shiny and soft!”


This BaBylissPRO porcelain ceramic straightening iron is made with porcelain ceramic, which distributes far-infrared heat evenly across the strands. Not only is it gentler and more healthy for your hair, but it can handle wide sections of hair at once because of its long barrel. The shape is rounded and sleek, so it’s ideal for curling, and it won’t catch or knot while you’re curling.
For some people, automatic shutoff is a critical feature since forgetting to unplug your flat iron could lead to a fire. However, others aren’t fans of auto shutoff since that means their flat irons could turn off while they’re still styling their hair. If this is the case for you, we recommend investing in a timed switch. That way, you can program the switch to turn off at a specific time and your flat iron will shut off as well.
