Professional Results

If you have thick or/and wavy hair, we'd recommend you to turn your eyes towards the Brazilian Tech™ Keratin 1" Straightening Iron. This styler stands out for its many innovative technologies and a great combo of high-quality materials. The plates here are made of titanium steel and coated with liquid Keratin which allows it to give the hair radiance and prevent heat damage. Thanks to the Sol-Gel technology, the plates literally glide over the hair and do not pull it, so you can enjoy the process and experience no discomfort. It's worth emphasizing that the Sol-Gel method is used only in the production of pro-grade tools, which adds appeal to the Brazilian Tech™ Keratin 1" Straightening Iron by bringing it on par with more expensive curlers. It also ensures ultimate heat and unprecedented performance results.

Also of note is that this styler offers a vast selection of heat settings allowing you to select one from 40 available, depending on your hair type. The max heat setting the straightener can reach is 450 degrees F, which is a salon result. This and adjustable temperature settings allow using it on hair of any structure. The tool can effectively eliminate frizz, curls, kinks, and cowlicks, turning your hair into a wholesome, beautiful thatch.

Summing up, this iron is suitable for home styling as well as for professional styling at salons. It can be easily used even for performing such straightening and smoothing procedures as Anticurl + Kerashine conditioning or thermal shiny str8. So, if you are searching for a pro-grade tool and aren't ready for compromises, the One’n Only™ Brazilian Tech™ flat iron is the one you need.

Remington S8598S

Ultimately Smart

The last thing girls want is to have their hair ruined after a straightening procedure. Which is why we all seek extra protection when choosing such a product as a flat iron. If that's exactly what you need, you won't go wrong with the Remington S8598S. It comes equipped with the proprietary SmartPRO sensor technology which allows it to detect the moisture levels of your hair and automatically adjust the heat so you can enjoy a gentle and, more importantly, safe styling experience at home. The use of this technology allowed reducing hair damage and breakage up to 3 times, compared to standard straighteners.

As for the plates, they are 1 inch wide and infused with a combo of Keratin and Almond oil to provide a smooth glide and extra conditioning. Despite "oily" coating, the iron doesn't leave oil residue; you can safely use it in the morning and be confident that your hair will look great.

The Remington S8598S heats up relatively fast. It takes about 15 seconds to reach the low setting and a bit more to heat up to 450 degrees F, the highest temperature that is best used only on extremely wild hair. For anyone with fine and thin hair, though, we'd recommend not to go for such extreme heat settings and stick with the other four options that can be adjusted with controls on the handle.

One of the best things about this straightener is that you don't need to wait until it cools. The manufacturer wisely included a silicone sleeve, in which you can pack it while it's still hot. All of this makes it a great styling tool, especially so for those people who are often on the go. It includes all the necessary safety features, it's small in size, and its performance is close to pro tools.

Keratin Complex Stealth V Digital

Ergonomic Design

Despite a seemingly simple construction, some straighteners can be less convenient to use than the others. We hear you asking why. Well, you might be surprised to hear it but inconvenient arrangement of buttons is what can make using even the most sophisticated model awkward. With that in mind, we'd like to introduce the Professional Ceramic Tourmaline Flat Iron to you, a straightener that features a different design and that can be used with no issues.

Unlike many irons featuring control buttons on the outside of the handle, the power on/of and temp buttons on this one are placed inside so you can grip it comfortably and worry not that you might accidentally hit them. The only thing you'll find on the exterior part is a LED digital display which will show you a pre-set heat setting. This makes the use of this flat iron stress-free and very convenient. Yet, what we like best about it is that it has a memory function. This means the iron automatically saves the last used settings and you don't need to adjust them every time you straighten your hair. Also great is that it has an auto shut-off function that powers the iron down after 40 minutes of non-use.

As for performance, the plates here are made out of tourmaline infused ceramic. This enables the straightener to not only smooth the hair but also give it a Keratin Ion boost so it looks healthy and shiny as well. The plates are 1.25 inches, which is a bit wider than average making it suitable for short and long hair alike. Plus, the plates are slightly rounded, which allows you to comfortably curl your hair, flip it and create amazing beachy waves as well.

For anyone needing quick and effective results, we couldn't recommend the Professional Ceramic Tourmaline Flat Iron highly enough.

Fine Expectations GS-007

Tames Extremely Wild Hair

When it comes to taming extremely coarse and curly hair, the very first thing to check in a straightener is the heat it can reach. In terms of the maximum temperature, the Fine Expectations flat iron matches the performance of big names. It instantly heats up to incredible 450 degrees F to make even extremely coarse hair much softer, shinier, and healthier! The thing that adds to its great performance is the tourmaline ceramic technology. The iron emits a huge amount of Keratin ions that reduce frizziness and make hair silky smooth in half the time compared to conventional straighteners.

The straightener features 1.25" floating plates that glide smoothly over your hair. They have an ergonomic edge design, allowing you to straighten or curl and flip your hair. As for the controls, they are conveniently located on the inside of the handles in such a way so that you won’t accidentally hit the buttons and change the temperature while styling. For extra safety, the unit will turn off after 40 minutes of non-use. So, if you need an ultra-safe and ultra-hot straightener to create sexy and shiny Victoria Secret style waves no matter what your hair structure is, this one will do the trick.

What Is a Keratin Flat Iron?

The advantage of Keratin straighteners is that they can be used on any hair type, they improve hair texture and make it shine.

Like the name suggests, these flat irons are infused with Keratin which allows them to preserve the hair’s natural protein and seal the moisture.

Plus, Keratin flat irons have pretty much the same design. Some of them may feature rounded edges so that you can curl your hair as well. For this review, we've picked five top models with different key features and different price tags so you can find what suits you best.
